金融体制、融资约束与投资——来自OECD的实证分析R.SemenovDepartment of Economics,University of Nijmegen,Nijmegen(荷兰内梅亨大学,经济学院)这篇论文考查了OECD的11个国家中现金流量对企业投资的影响.我们发现不同国家之间投资对企业内部可获取资金的敏感性具有显著差异,并且银企之间具有明显的紧密关系的国家的敏感性比银企之间具有公平关系的国家的低.同时,我们发现融资约束与整体金融发展指标不存在关系.我们的结论与资本市场信息和激励问题对企业投资具有重要作用这种观点一致,并且紧密的银企关系会减少这些问题从而增加企业获取外部融资的渠道。

一、引言各个国家的企业在显著不同的金融体制下运行。

金融发展水平的差别(例如,相对GDP的信用额度和相对GDP的相应股票市场的资本化程度),在所有者和管理者关系、企业和债权人的模式中,企业控制的市场活动水平可以很好地被记录.在完美资本市场,对于具有正的净现值投资机会的企业将一直获得资金。

然而,经济理论表明市场摩擦,诸如信息不对称和激励问题会使获得外部资本更加昂贵,并且具有盈利投资机会的企业不一定能够获取所需资本.这表明融资要素,例如内部产生资金数量、新债务和权益的可得性,共同决定了企业的投资决策.现今已经有大量考查外部资金可得性对投资决策的影响的实证资料(可参考,例如Fazzari(1998)、 Hoshi(1991)、 Chapman(1996)、Samuel(1998)).大多数研究结果表明金融变量例如现金流量有助于解释企业的投资水平。

这项研究结果解释表明企业投资受限于外部资金的可得性。

很多模型强调运行正常的金融中介和金融市场有助于改善信息不对称和交易成本,减缓不对称问题,从而促使储蓄资金投着长期和高回报的项目,并且提高资源的有效配置(参看Levine(1997)的评论文章)。

因而我们预期用于更加发达的金融体制的国家的企业将更容易获得外部融资.几位学者已经指出建立企业和金融中介机构可进一步缓解金融市场摩擦。

外文文献翻译译稿1卡尔曼滤波的一个典型实例是从一组有限的,包含噪声的,通过对物体位置的观察序列(可能有偏差)预测出物体的位置的坐标及速度。

在很多工程应用(如雷达、计算机视觉)中都可以找到它的身影。

同时,卡尔曼滤波也是控制理论以及控制系统工程中的一个重要课题。

例如,对于雷达来说,人们感兴趣的是其能够跟踪目标。

但目标的位置、速度、加速度的测量值往往在任何时候都有噪声。

卡尔曼滤波利用目标的动态信息,设法去掉噪声的影响,得到一个关于目标位置的好的估计。

这个估计可以是对当前目标位置的估计(滤波),也可以是对于将来位置的估计(预测),也可以是对过去位置的估计(插值或平滑)。

外文资料Nanotechnology and Micro-machine原文(一):NanomaterialNanomaterials and nanotechnology have become a magic word in modern society.Nanomaterials represent today’s cutting edge in the development of novel advanced materials which promise tailor-made functionality and unheard applications in all key technologies. So nanomaterials are considered as a great potential in the 21th century because of their special properties in many fields such as optics, electronics, magnetics, mechanics, and chemistry. These unique properties are attractive for various high performance applications. Examples include wear resistant surfaces, low temperature sinterable high-strength ceramics, and magnetic nanocomposites. Nanostructures materials present great promises and opportunities for a new generation of materials with improved and marvelous properties.It is appropriate to begin with a brief introduction to the history of the subject. Nanomaterials are found in both biological systems and man-made structures. Nature has been using nanomaterials for millions of years,as Disckson has noted: “Life itself could be regarded as a nanophase system”.Examples in which nanostructured elements play a vital role are magnetotactic bacteria, ferritin, and molluscan teeth. Several species of aquatic bacteria use the earth’s magnetic field to orient thenselves. They are able to do this because they contain chains of nanosized, single-domain magnetite particles. Because they have established their orientation, they are able to swim down to nutriments and away from what is lethal to them ,oxygen. Another example of nanomaterials in nature is that herbivorous mollusks use teeth attached to a tonguelike organ, the radula, to scrape their food. These teeth have a complexstructure containing nanocrystalline needles. We can utilize biological templates formaking nanomaterials. Apoferritin has been used as a confined reaction environmentfor the synthesis of nanosized magnetite particles. Some scholars consider biologicalnanomaterials as model systems for developing technologically useful nanomaterials.Scientific work on this subject can be traced back over 100 years.In 1861 theBritish chemist Thomas Graham coined the term colloid to describe a solutioncontaining 1 to 100 nm diameter particles in suspension. Around the turn of thecentury, such famous scientists as Rayleigh, Maxwell, and Einstein studied colloids.In 1930 the Langmuir-Blodgett method for developing monolayer films wasdeveloped. By 1960 Uyeda had used electron microscopy and diffraction to studyindividual particles. At about the same time, arc, plasma, and chemical flame furnaceswere employed to prouduce submicron particles. Magnetic alloy particles for use inmagnetic tapes were produced in 1970.By 1980, studies were made on clusterscontaining fewer than 100 atoms .In 1985, a team led by Smalley and Kroto foundC clusters were unusually stable. In 1991, Lijima spectroscopic evidence that 60reported studies of graphitic carbon tube filaments.Research on nanomaterials has been stimulated by their technologicalapplications. The first technological uses of these materials were as catalysts andpigments. The large surface area to volume ratio increases the chemicalactivity.Because of this increased activity, there are significant cost advantages infabricating catalysts from nanomaterials. The peoperties of some single-phasematerials can be improved by preparing them as nanostructures. For example, thesintering temperature can be decreased and the plasticity increased on single-phase,structural ceramics by reducing the grain size to several nanometers. Multiphasenanostructured materials have displayed novel behavior resulting from the small sizeof he individual phases.Technologically useful properties of nanomaterials are not limited to theirstructural, chemical, or mechanical behavior. Multilayers represent examples ofmaterials in which one can modify of tune a property for a specific application bysensitively controlling the individual layer thickness. It was discovered that the resistance of Fe-Cr multilayered thin films exhibited large changes in an applied magnetic field of several tens of kOe.This effect was given the name giant magnetoresistance (GMR). More recently, suitably annealed magnetic multilayers have been developed that exhibit significant magnetoresistance effects even in fields as low as 5 to10 Oe (Oersted). This effect may prove to be of great technological importance for use in magnetic recording read heads.In microelectronics, the need for faster switching times and ever larger integration has motivated considerable effort to reduce the size of electronic components. Increasing the component density increases the difficulty of satisfying cooling requirements and reduces the allowable amount of energy released on switching between states. It would be ideal if the switching occurred with the motion of a single electron. One kind of single-electron device is based on the change in the Coulombic energy when an electron is added or removed from a particle. For a nanoparticle this enery change can be large enough that adding a single electron will effectively blocks the flow of other electrons. The use of Coulombic repulsion in this way is called Coulomb blockade.In addition to technology, nanomaterials are also interesting systems for basic scientific investigations .For example, small particles display deviations from bulk solid behavior such as reductios in the melting temperature and changes (usually reductions) in the lattice parameter. The changes n the lattice parameter observed for metal and semiconductor particles result from the effect of the surface free energy. Both the surface stress and surface free energy are caused by the reduced coordination of the surface atoms. By studying the size dependence of the properties of particles, it is possible to find the critical length scales at which particles behave essentially as bulk matter. Generally, the physical properties of a nanoparticle approach bulk values for particles containing more than a few hundred atoms.New techniques have been developed recently that have permitted researchers to produce larger quantities of other nanomaterials and to better characterize these materials.Each fabrication technique has its own set of advantages anddisadvantages.Generally it is best to produce nanoparticles with a narrow size distribution. In this regard, free jet expansion techniques permit the study of very small clusters, all containing the same number of atoms. It has the disadvantage of only producing a limited quantity of material.Another approach involves the production of pellets of nanostructured materials by first nucleating and growing nanoparticles in a supersaturated vapor and then using a cold finger to collect the nanoparticle. The nanoparticles are then consolidated under vacuum. Chemical techniques are very versatile in that they can be applied to nearly all materials (ceramics, semiconductors, and metals) and can usually produce a large amount of material. A difficulty with chemical processing is the need to find the proper chemical reactions and processing conditions for each material. Mechanical attrition, which can also produce a large amount of material, often makes less pure material. One problem common to all of these techniques is that nanoparticles often form micron-sized agglomerates. If this occurs, the properties of the material may be determined by the size of the agglomerate and not the size of the individual nanoparticles. For example, the size of the agglomerates may determine the void size in the consolidated nanostructured material.The ability to characterize nanomaterials has been increased greatly by the invention of the scanning tunneling microscope (STM) and other proximal probes such as the atomic force microscope (AFM), the magnetic force microscope, and the optical near-field microscope.SMT has been used to carefully place atoms on surfaces to write bits using a small number of atmos. It has also been employed to construct a circular arrangement of metal atoms on an insulating surface. Since electrons are confined to the circular path of metal atoms, it serves ad a quantum ‘corral’of atoms. This quantum corral was employed to measure the local electronic density of states of these circular metallic arrangements. By doing this, researchers were able to verify the quantum mechanical description of electrons confined in this way.Other new instruments and improvements of existing instruments are increasingly becoming important tools for characterizing surfaces of films, biological materials, and nanomaterials.The development of nanoindentors and the improvedability to interpret results from nanoindentation measurements have increased our ability to study the mechanical properties of nanostructured materials. Improved high-resolution electron microscopes and modeling of the electron microscope images have improved our knowledges of the structure of the the particles and the interphase region between particles in consolidated nanomaterials.Nanotechnology1. IntroductionWhat id nanotechnology? it is a term that entered into the general vocabulary only in the late 1970’s,mainly to describe the metrology associated with the development of X-ray,optical and other very precise components.We defined nanotechnology as the technology where dimensions and tolerances in the range 0.1~100nm(from the size of the atom to the wavelength of light) play a critical role.This definition is too all-embracing to be of practical value because it could include,for example,topics as diverse as X-ray crystallography ,atomic physics and indeed the whole of chemistry.So the field covered by nanotechnology is later narrowed down to manipulation and machining within the defined dimensional range(from 0.1nm to 100nm) by technological means,as opposed to those used by the craftsman,and thus excludes,for example,traditional forms of glass polishing.The technology relating to fine powders also comes under the general heading of nanotechnology,but we exclude observational techniques such as microscopy and various forms of surface analysis.Nanotechnology is an ‘enabling’ technology, in that it provides the basis for other technological developments,and it is also a ‘horizontal’or ‘cross-sectional’technology in that one technological may,with slight variations,be applicable in widely differing fields. A good example of this is thin-film technology,which is fundamental to electronics and optics.A wide range of materials are employed in devices such as computer and home entertainment peripherals, including magnetic disc reading heads,video cassette recorder spindles, optical disc stampers and ink jet nozzles.Optical and semiconductor components include laser gyroscope mirrors,diffraction gratings,X-ray optics,quantum-well devices.2. Materials technologyThe wide scope of nanotechnology is demonstrated in the materials field,where materials provide a means to an end and are not an end in themseleves. For example, in electronics,inhomogeneities in materials,on a very fine scale, set a limit to the nanometre-sized features that play an important part in semiconductor technology, and in a very different field, the finer the grain size of an adhesive, the thinner will be the adhesive layer, and the higher will be the bond strength.(1) Advantages of ultra-fine powders. In general, the mechanical, thermal, electrical and magnetic properties of ceramics, sintered metals and composites are often enhanced by reducing the grain or fiber size in the starting materials. Other properties such as strength, the ductile-brittle transition, transparency, dielectric coefficient and permeability can be enhanced either by the direct influence of an ultra-fine microstructure or by the advantages gained by mixing and bonding ultra-fine powders.Oter important advantages of fine powders are that when they are used in the manufacture of ceramics and sintered metals, their green (i.e, unfired) density can be greatly increased. As a consequence, both the defects in the final produce and the shrinkage on firing are reduced, thus minimizing the need for subsequent processing.(2)Applications of ultra-fine powders.Important applications include:Thin films and coatings----the smaller the particle size, the thinner the coating can beElectronic ceramics ----reduction in grain size results in reduced dielectric thicknessStrength-bearing ceramics----strength increases with decreasing grain sizeCutting tools----smaller grain size results in a finer cutting edge, which can enhance the surface finishImpact resistance----finer microstructure increases the toughness of high-temperature steelsCements----finer grain size yields better homogeneity and densityGas sensors----finer grain size gives increased sensitivityAdhesives----finer grain size gives thinner adhesive layer and higher bond strength3. Precision machining and materials processingA considerable overlap is emerging in the manufacturing methods employed in very different areas such as mechanical engineering, optics and electronics. Precision machining encompasses not only the traditional techniques such as turning, grinding, lapping and polishing refined to the nanometre level of precision, but also the application of ‘particle’ beams, ions, electrons and X-rays. Ion beams are capable of machining virtually any material and the most frequent applications of electrons and X-rays are found in the machining or modification of resist materials for lithographic purposes. The interaction of the beams with the resist material induces structural changes such as polymerization that alter the solubility of the irradiated areas.(1) Techniques1) Diamond turning. The large optics diamond-turning machine at the Lawrence Livermore National Laboratory represents a pinnacle of achievement in the field of ultra-precision machine tool engineering. This is a vertical-spindle machine with a face plate 1.6 m in diameter and a maximum tool height of 0.5m. Despite these large dimensions, machining accuracy for form is 27.5nm RMS and a surface roughness of 3nm is achievable, but is dependent both on the specimen material and cutting tool.(2) GrindingFixed Abrasive Grinding The term“fixed abrasive” denotes that a grinding wheel is employed in which the abrasive particles, such as diamond, cubic boron nitride or silicon carbide, are attached to the wheel by embedding them in a resin or a metal. The forces generated in grinding are higher than in diamond turning and usually machine tools are tailored for one or the other process. Some Japanese work is in the vanguard of precision grinding, and surface finishes of 2nm (peak-to-valley) have been obtained on single-crystal quartz samples using extremely stiff grinding machinesLoose Abrasive Grinding The most familiar loose abrasive grinding processes are lapping and polishing where the workpiece, which is often a hard material such asglass, is rubbed against a softer material, the lap or polisher, with abrasive slurry between the two surfaces. In many cases, the polishing process occurs as a result of the combined effects of mechanical and chemical interaction between the workpiece, slurry and polished.Loose abrasive grinding techniques can under appropriate conditions produce unrivalled accuracy both in form and surface finish when the workpiece is flat or spherical. Surface figures to a few nm and surface finishes bettering than 0.5nm may be achieved. The abrasive is in slurry and is directed locally towards the workpiece by the action of a non-contacting polyurethane ball spinning at high speed, and which replac es the cutting tool in the machine. This technique has been named “elastic emission machining” and has been used to good effect in the manufacture of an X-ray mirror having a figure accuracy of 10nm and a surface roughness of 0.5nm RMS.3)Thin-film production. The production of thin solid films, particularly for coating optical components, provides a good example of traditional nanotechnology. There is a long history of coating by chemical methods, electro-deposition, diode sputtering and vacuum evaporation, while triode and magnetron sputtering and ion-beam deposition are more recent in their wide application.Because of their importance in the production of semiconductor devices, epitaxial growth techniques are worth a special mention. Epitaxy is the growth of a thin crystalline layer on a single-crystal substrate, where the atoms in the growing layer mimic the disposition of the atoms in the substrate.The two main classes of epitaxy that have ben reviewed by Stringfellow (1982) are liquid-phase and vapour-phase epitaxy. The latter class includes molecular-beam epitaxy (MBE), which in essence, is highly controlled evaporation in ultra high vacuum. MBE may be used to grow high quality layered structures of semiconductors with mono-layer precision, and it is possible to exercise independent control over both the semiconductor band gap, by controlling the composition, and also the doping level. Pattern growth is possible through masks and on areas defined by electron-beam writing.4. ApplicationsThere is an all-pervading trend to higher precision and miniaturization, and to illustrate this a few applications will be briefly referred to in the fields of mechanical engineering,optics and electronics. It should be noted however, that the distinction between mechanical engineering and optics is becoming blurred, now that machine tools such as precision grinding machines and diamond-turning lathes are being used to produce optical components, often by personnel with a backgroud in mechanical engineering rather than optics. By a similar token mechanical engineering is also beginning to encroach on electronics particularly in the preparation of semiconductor substrates.(1) Mechanical engineeringOne of the earliest applications of diamond turning was the machining of aluminum substrates for computer memory discs, and accuracies are continuously being enhanced in order to improve storage capacity: surface finishes of 3nm are now being achieved. In the related technologies of optical data storage and retrieval, the toler ances of the critical dimensions of the disc and reading head are about 0.25 μm. The tolerances of the component parts of the machine tools used in their manufacture, i.e.the slideways and bearings, fall well within the nanotechnology range.Some precision components falling in the manufacturing tolerance band of 5~50nm include gauge blocks, diamond indenter tips, microtome blades, Winchester disc reading heads and ultra precision XY tables (Taniguchi 1986). Examples of precision cylindrical components in two very different fields, and which are made to tolerances of about 100 nm, are bearing for mechanical gyroscopes and spindles for video cassette recorders.The theoretical concept that brittle materials may be machined in a ductile mode has been known for some time. If this concept can be applied in practice it would be of significant practical importance because it would enable materials such as ceramics, glasses and silicon to be machined with minimal sub-surface damage, and could eliminate or substantially reduce the need for lapping and polishing.Typically, the conditions for ductile-mode machining require that the depth of cutis about 100 nm and that the normal force should fall in the range of 0.1~0.01N. These machining conditons can be realized only with extremely precise and stiff machine tools, such as the one described by Yoshioka et al (1985), and with which quartz has been ground to a surface roughness of 2 nm peak-to-valley. The significance of this experimental result is that it points the way to the direct grinding of optical components to an optical finish. The principle can be extended to other materials of significant commercial importance, such as ceramic turbine blades, which at present must be subjected to tedious surface finishing procedures to remove the structure-weakening cracks produced by the conventional grinding process.(2) OpticsIn some areas in optics manufacture there is a clear distinction between the technological approach and the traditional craftsman’s approach, particul arly where precision machine tools are employed. On the other hand, in lapping and polishing, there is a large grey area where the two approaches overlap. The large demand for infrared optics from the 1970s onwards could not be met by the traditional suppliers, and provided a stimulus for the development and application of diamond-turning machines to optic manufacture. The technology has now progressed and the surface figure and finishes that can be obtained span a substantial proportion of the nanotechnology range. Important applications of diamond-turned optics are in the manufacture of unconventionally shaped optics, for example axicons and more generelly, aspherics and particularly off-axis components. Such as paraboloids.The mass production(several million per annum) of the miniature aspheric lenses used in compact disc players and the associated lens moulds provides a good example of the merging of optics and precision engineering. The form accuracy must be better than 0.2μm and the surface roughness m ust be below 20 nm to meet the criterion for diffraction limited performance.(3) ElectronicsIn semiconductors, nanotechnology has long been a feature in the development of layers parallel to the substrate and in the substrate surface itself, and the need for precision is steadily increasing with the advent of layered semiconductor structures.About one quarter of the entire semiconductor physics community is now engaged in studying aspects of these structures. Normal to the layer surface, the structure is produced by lithography, and for research purposes ar least, nanometre-sized features are now being developed using X-ray and electron and ion-beam techniques.5. A look into the futureWith a little imagination, it is not difficult to conjure up visions of future developments in high technology, in whatever direction one cares to look. The following two examples illustrate how advances may take place both by novel applications and refinements of old technologies and by development of new ones.(1) Molecular electronicsLithography and thin-film technology are the key technologies that have made possible the continuing and relentless reduction in the size of integrated circuits, to increase both packing density and operational speed. Miniaturization has been achieved by engineering downwards from the macro to the micro scale. By simple extrapolation it will take approximately two decades for electronic switches to be reduced to molecular dimensions. The impact of molecular biology and genetic engineering has thus provided a stimulus to attempt to engineer upwards, starting with the concept that single molecules, each acting as an electronic device in their own right, might be assembled using biotechnology, to form molecular electronic devices or even biochip computers.Advances in molecular electronics by downward engineering from the macro to the micro scale are taking place over a wide front. One fruitful approach is by way of the Langmure-Biodgett (LB) film using a method first described by Blodgett (1935).A multi-layer LB structure consists of a sequence of organic monolayers made by repeatedly dipping a substrate into a trough containing the monolayer floating on a liquid (usually water), one layer being added at a time. The classical film forming materials were the fatty acids such as stearic acid and their salts. The late 1950s saw the first widespread and commercially important application of LB films in the field of X-ray spectroscopy (e.g, Henke 1964, 1965). The important properties of the films that were exploited in this application were the uniform thickness of each film, i.e.one molecule thick, and the range of thickness, say from 5to 15nm, which were available by changing the composition of the film material. Stacks of fifty or more films were formed on plane of curved substrates to form two-dimensional diffraction gratings for measuring the characteristic X-ray wavelengths of the elements of low atomic number for analytical purposes in instruments such as the electron probe of X-ray micro-analyzer.(2) Scanning tunneling engineeringIt was stated that observational techniques such as microscopy do mot, at least for the purposes of this article, fall within the domain of nanotechnology. However,it is now becoming apparent that scanning tunneling microscopy(STM) may provide the basis of a new technology, which we shall call scanning tunneling engineering.In the STM, a sharp stylus is positioned within a nanometre of the surface of the sample under investigation. A small voltage applied between the sample and the stylus will cause a current to foow through the thin intervening insulating medium (e.g.air, vacum, oxide layer). This is the tunneling electron current which is exponentially dependent on the sample-tip gap. If the sample is scanned in a planr parallel to ies surface and if the tunneling current is kept cnstant by adjusting the height of the stylus to maintain a constant gap, then the displacement of the stylus provides an accurate representation of the surface topographyu of the sample. It is relevant to the applications that will be discussed that individual atoms are easily resolved by the STM, that the stylus tip may be as small as a single atom and that the tip can be positioned with sub-atomic dimensional accuracy with the aid of a piezoelectric transducer.The STM tip has demonstrated its ability to draw fine lines, which exhibit nanometre-sized struture, and hence may provide a new tool for nanometre lithography.The mode of action was not properly understood,but it was suspected that under the influence of the tip a conducting carbon line had been drawn as the result of polymerizing a hydrocarbon film, the process being assisted by the catalytic activity of the tungsten tip. By extrapolating their results the authors believed that it would be possible to deposit fine conducting lines on an insulating film. The tip would operatein a gaseous environment that contained the metal atoms in such a form that they could either be pre-adsorbed on the film or then be liberated from their ligands or they would form free radicals at the location of the tip and be transferred to the film by appropriate adjustment of the tip voltage.Feynman proposed that machine tools be used to make smaller machine tools which in turn would make still smaller ones, and so on all the way down to the atomic level. These machine tools would then operate via computer control in the nanometre domain, using high resolution electron microscopy for observation and control. STM technology has short-cricuired this rather cumbrous concept,but the potential applications and benefits remain.原文(二)Micro-machine1. IntroductionFrom the beginning, mankind seems instinctively to have desired large machines and small machines. That is, “large” and “small” in comp arison with human-scale. Machines larger than human are powerful allies in the battle against the fury of nature; smaller machines are loyal partners that do whatever they are told.If we compare the facility and technology of manufacturing larger machines, common sense tells us that the smaller machines are easier to make. Nevertheless, throughout the history of technology, larger machines have always stood ort. The size of the restored models of the water-mill invented by Vitruvius in the Roman Era, the windmill of the middle Ages, and the steam engine invented by Watt is overwhelming. On the other hand, smaller machined in history of technology are mostly tools. If smaller machines are easier to make, a variety of such machined should exist, but until modern times, no significant small machines existed except for guns and clocks.This fact may imply that smaller machines were actually more difficult to make. Of course, this does not mean simply that it was difficult to make a small machine; it means that it was difficult to invent a small machine that would be significant to human beings.。

Awareness among the hoteliers and the guests has fuelled the inventions focused on operations. The increased sagacity of customer satisfaction led to the use of high standards of service in industry. The new service parameters made the hoteliers to implement quality management as an effective aid. It has significantly affected hotels' ability to control and adapt to changing environments. The use of new techniques began with the simple motive of sophistication and precise activities in the given field of operation which may result in high standards of service in global economy and has allowed the rise of a leisure class.Conceptual Framework This study of Service quality management in hospitality industry is an attempt to understand the presence of quality improvement process in hospitality industry and effectiveness in making it sustainable business enterprise. It is a survey of the presently adopted quality management tools which are making the hotels operations safer, focused and reliable and meet the customer expectations.As the hospitality industry becomes more competitive there is an obvious need to retain clientele as well as increasing profitability and hence management professionals strive to improve guest satisfaction and revenues. The management professionals whom are striving for these results however often have limited understanding of research surrounding the paradigms of guest satisfaction and loyalty and financial performance. This research paper shall enlighten some of the variables and important facts of service quality resulting into guest satisfaction.Review of LiteratureCustomers of hospitality often blame themselves when dissatisfied for their bad choice. Employees must be aware that dissatisfied customers may not complain and therefore the employees should seek out sources of dissatisfaction and resolve them. (Zeithaml V., 1981, p.186 -190)It is said that service quality is what differentiates hospitality sector, however there is not an agreed definition of what service quality is. There is however a few different suggestions of how to define service quality. Dividing it into technical, functional and image components; (Greenrooms C., 1982) another is that service quality is determined by its fitness for use by internal and external customers. It is accepted that service quality is depends upon guest's needs and expectations. A definition of service quality state that quality is simply conformance to specifications, which would mean that positive quality is when a product or service specific quality meet or exceed preset standards or promises. This however seems like an easy viewwithin the hospitality industry. The alternative definitions read as follows: 1) quality is excellence; 2) quality is value for money; 3) quality is meeting or exceeding expectations. This appears better aligned with ideas which exist within hospitality management than the first mentioned simplistic approach. Service quality and value is rather difficult to calculate, companies must therefore rely on guest's quality perceptions and expectations to get consistent results which is best achieved by asking guest's questions related to expectations and their perceptions of the service quality, which can effectively be achieved through carefully designed surveys.A major problem with service quality is variability and limited capability and robustness of the service production process. (Gummesson E., 1991) Hotels consumers have well-conceived ideas about service quality and quality attributes are considered important for most types of services, the absence of certain attributes may lead consumers to perceive service quality as poor. The presence of these attributes may not substantially improve the perceived quality of the service. Most customers would be willing to trade some convenience for a price break, and that the behavior, skill level and performance of service employees are key determinants of perceived quality of services. This is a major challenge in improving or maintaining a high level of service quality. (Tigineh M. et al 1992)Studies focusing on service quality management suggest that service firms spend too little effort on planning for service quality. The resultant costs of poor service quality planning lead to lower profitability as part of the service failures.(Stuart F., et al 1996)When discussing satisfaction, it is important to understand that guest's evaluation of service comprise of two basic distinct dimensions: service delivery and service outcome (Mattila, 1999). Research indicates that how the service was delivered (perceived functional quality) is more important than the outcome of the service process (technical quality). This research clearly indicates that effort by staff have a strong effect on guest's satisfaction judgments.Companies delivering services must broaden their examination of productivity to help settle conflicts – the leverage synergies – between improving service quality and boosting service productivity. ( Parasuraman A. 2002)A key activity is to conduct regularly scheduled review of progress by quality council or working group and management must establish a system to identify areas for future improvement and to track performance with respect to internal and external customers. They must also track the changing preferences of customer. Continuous improvement means not only being satisfied with doing a good job or process. It is accomplished by incorporating process measurement and team problem solving an all work activities. Organization must continuously strive for excellence by reducing complexity, variation and out of control process. Plan-D-Study-Act (PDSA) developed by Shewhart and later on modified by Deming is an effective improvement technique. First Plan carefully, then carry out plan, study the results and check whether the plan worked exactly as intended and act on results by identifying what worked as planned and what didn't work.Continuous process improvement is the objective and these phases of PDSA are the framework to achieve those objectives. (Besterfield D. et al 2003) The 'servicescape' -is a general term to describe the physical surroundings of a service environment (Reimer 2005, p. 786) such as a hotel or cruise ship. Guests are sometimes unconsciously trying to obtain as much information as possible through experiences to decrease information asymmetries This causes guests to look for quality signals or cues which would provide them with information about the service, which leads us to 'cue utilization theory'. Cue utilization theory states that products or services consist of several arrays of cues that serve as surrogate indicators of product or service quality. There are both intrinsic and extrinsic cues to help guests determine quality. Consequentially, due to the limited tangibility of services, guests are often left to accept the price of the experience and the physical appearance or environment of the hotel or cruise ship itself as quality indicators. Though there are many trade and academic papers discussing guest satisfaction has been published, one can note that limited attention has been paid to the value perception and expectations guests have towards product delivery and influence price guests pay for an experience has on satisfaction and future spending. Furthermore it is also known that the role of pricing in relation to guest determinants of perceived quality of services. This is a major challenge in improving or maintaining a high level of service quality. (Tigineh M. et al 1992) Studies focusing on service quality management suggest that service firms spend too little effort on planning for service quality.The resultant costs of poor service quality planning lead to lower profitability as part of the service failures. (Stuart F., et al 1996)When discussing satisfaction, it is important to understand that guest's evaluation of service comprise of two basic distinct dimensions: service delivery and service outcome (Mattila, 1999). Research indicates that how the service was delivered (perceived functional quality) is more important than the outcome of the service process (technical quality). This research clearly indicates that effort by staff have a strong effect on guest's satisfaction judgments. Companies delivering services must broaden their examination of productivity to help settle conflicts –the leverage synergies –between improving service quality and boosting service productivity. ( Parasuraman A. 2002)Telephonic conversation with peers and friends in hospitality industry worked a wonder giving lots of inputs in drafting this paper. Secondary data sources- For this study, data sources such as hospitality journals, Books on service quality management, organization behavior, URL on internet of various hospitality majors. Referring hospitality publications were helpful in knowing the current inventions in industry.Research Tools: Descriptive research design is used to know the attributes of service quality management in hospitality industry. Exploratory research design is undertaken to dig out the service quality management practices and its effectiveness. Data analysis is done and presented in tables. The hypothesis is tested against the collected data.Hypotheses: The hypotheses framed for the subject areHypothesis 1: Implementing service quality management as a tool for improvement in Customer Satisfaction.Hypothesis 2: Practicing Continuous Improvement program has benefited hotel. Limitation & Scope of the Study: Though there was a specific questionnaire used for collecting information, the objective of the paper was well discussed with the every contributor and whatever the information was provided by these sources is arranged for further analysis. The analysis of the available data is done on the relevance to the topic. The effectiveness of the technology in conservation of resources was always a point of consideration. The data is sifted for making it as precise as possible.Analysis and DiscussionsThere is a significant relationship between service quality management and customer satisfaction. In hospitality industry, the customer satisfaction variables such as Availability, Access, Information, Time, delivery of service, availability of personal competence, Comfortable and safer atmosphere and pollution free environment are of prime concern to every hotelier. The industry continuously tries to improve upon their services to meet the levels of customer satisfaction.The intangible nature of the service as a product means that it could be very difficult to place quantifiable terms on the features that contribute to the quality and measurement of the quality of the product is a problem for Service quality management.The customer is frequently directly involved in the delivery of the service and as such introduces an unknown and unpredictable influence on the process. The customer variability in the process makes it difficult to determine the exact requirements of the customer and what they regard as an acceptable standard of service.This problem is magnified as it is often judgmental, based on personal preferences or even mood, rather than on technical performance that can be measured. Every hotel has a target market to cater which has very specific requirement in terms of expected and perceived quality of service.The customers come with different perception of quality every time they come to hotel and this makes it quite difficult to define quality and set the level of it. It requires hotel to continuously compare their perception against customer perception in terms of satisfaction measurement with performance measurement. The study has shown that the effective tools which management of various hotels uses for continuous improvement process and how it is dissipated amongst all the stake holders.译文酒店业服务质量管理研究博卡;萨米尔摘要本文旨在研究酒店业中质量改进过程的作用以及如何有效地推动企业的可持续发展。

第1页 共19页中文3572字毕业论文(设计)外文翻译标题:危机管理-预防,诊断和干预一、外文原文标题:标题:Crisis management: prevention, diagnosis and Crisis management: prevention, diagnosis andintervention 原文:原文:The Thepremise of this paper is that crises can be managed much more effectively if the company prepares for them. Therefore, the paper shall review some recent crises, theway they were dealt with, and what can be learned from them. Later, we shall deal with the anatomy of a crisis by looking at some symptoms, and lastly discuss the stages of a crisis andrecommend methods for prevention and intervention. Crisis acknowledgmentAlthough many business leaders will acknowledge thatcrises are a given for virtually every business firm, many of these firms do not take productive steps to address crisis situations. As one survey of Chief Executive officers of Fortune 500 companies discovered, 85 percent said that a crisisin business is inevitable, but only 50 percent of these had taken any productive action in preparing a crisis plan(Augustine, 1995). Companies generally go to great lengths to plan their financial growth and success. But when it comes to crisis management, they often fail to think and prepare for those eventualities that may lead to a company’s total failure.Safety violations, plants in need of repairs, union contracts, management succession, and choosing a brand name, etc. can become crises for which many companies fail to be prepared untilit is too late.The tendency, in general, is to look at the company as a perpetual entity that requires plans for growth. Ignoring the probabilities of disaster is not going to eliminate or delay their occurrences. Strategic planning without inclusion ofcrisis management is like sustaining life without guaranteeinglife. One reason so many companies fail to take steps to proactively plan for crisis events, is that they fail to acknowledge the possibility of a disaster occurring. Like an ostrich with its head in the sand, they simply choose to ignorethe situation, with the hope that by not talking about it, it will not come to pass. Hal Walker, a management consultant, points out “that decisions will be more rational and better received, and the crisis will be of shorter duration, forcompanies who prepare a proactive crisis plan” (Maynard, 1993) .It is said that “there are two kinds of crises: those that thatyou manage, and those that manage you” (Augustine, 1995). Proactive planning helps managers to control and resolve a crisis. Ignoring the possibility of a crisis, on the other hand,could lead to the crisis taking a life of its own. In 1979, theThree-Mile Island nuclear power plant experienced a crisis whenwarning signals indicated nuclear reactors were at risk of a meltdown. The system was equipped with a hundred or more different alarms and they all went off. But for those who shouldhave taken the necessary steps to resolve the situation, therewere no planned instructions as to what should be done first. Hence, the crisis was not acknowledged in the beginning and itbecame a chronic event.In June 1997, Nike faced a crisis for which they had no existi existing frame of reference. A new design on the company’s ng frame of reference. A new design on the company’s Summer Hoop line of basketball shoes - with the word air writtenin flaming letters - had sparked a protest by Muslims, who complained the logo resembled the Arabic word for Allah, or God.The council of American-Islamic Relations threatened aa globalNike boycott. Nike apologized, recalled 38,000 pairs of shoes,and discontinued the line (Brindley, 1997). To create the brand,Nike had spent a considerable amount of time and money, but hadnever put together a general framework or policy to deal with such controversies. To their dismay, and financial loss, Nike officials had no choice but to react to the crisis. This incident has definitely signaled to the company that spending a little more time would have prevented the crisis. Nonetheless,it has taught the company a lesson in strategic crisis management planning.In a business organization, symptoms or signals can alert the strategic planners or executives of an eminent crisis. Slipping market share, losing strategic synergy anddiminishing productivity per man hour, as well as trends, issues and developments in the socio-economic, political and competitive environments, can signal crises, the effects of which can be very detrimental. After all, business failures and bankruptcies are not intended. They do not usually happen overnight. They occur more because of the lack of attention to symptoms than any other factor.Stages of a crisisMost crises do not occur suddenly. The signals can usuallybe picked up and the symptoms checked as they emerge. A company determined to address these issues realizes that the real challenge is not just to recognize crises, but to recognize themin a timely fashion (Darling et al., 1996). A crisis can consistof four different and distinct stages (Fink, 1986). The phasesare: prodromal crisis stage, acute crisis stage, chronic crisisstage and crisis resolution stage.Modern organizations are often called “organic” due tothe fact that they are not immune from the elements of their surrounding environments. Very much like a living organism, organizations can be affected by environmental factors both positively and negatively. But today’s successfulorganizations are characterized by the ability to adapt by recognizing important environmental factors, analyzing them, evaluating the impacts and reacting to them. The art of strategic planning (as it relates to crisis management)involves all of the above activities. The right strategy, in general, provides for preventive measures, and treatment or resolution efforts both proactively and reactively. It wouldbe quite appropriate to examine the first three stages of acrisis before taking up the treatment, resolution or intervention stage.Prodromal crisis stageIn the field of medicine, a prodrome is a symptom of the onset of a disease. It gives a warning signal. In business organizations, the warning lights are always blinking. No matter how successful the organization, a number of issues andtrends may concern the business if proper and timely attentionis paid to them. For example, in 1995, Baring Bank, a UK financial institution which had been in existence since 1763,ample opportunitysuddenly and unexpectedly failed. There wasfor the bank to catch the signals that something bad was on thehorizon, but the company’s efforts to detect that were thwarted by an internal structure that allowed a single employee both to conduct and to oversee his own investment trades, and the breakdown of management oversight and internalcontrol systems (Mitroff et al., 1996). Likewise, looking in retrospect, McDonald’s fast food chain was given the prodromalsymptoms before the elderly lady sued them for the spilling ofa very hot cup of coffee on her lap - an event that resulted in a substantial financial loss and tarnished image of thecompany. Numerous consumers had complained about thetemperature of the coffee. The warning light was on, but the company did not pay attention. It would have been much simplerto pick up the signal, or to check the symptom, than facing the consequences.In another case, Jack in the Box, a fast food chain, had several customers suffer intestinal distress after eating at their restaurants. The prodromal symptom was there, but the company took evasive action. Their initial approach was to lookaround for someone to blame. The lack of attention, the evasiveness and the carelessness angered all the constituent groups, including their customers. The unfortunate deaths thatptoms,occurred as a result of the company’s ignoring thesymand the financial losses that followed, caused the company to realize that it would have been easier to manage the crisis directly in the prodromal stage rather than trying to shift theblame.Acute crisis stageA prodromal stage may be oblique and hard to detect. The examples given above, are obvious prodromal, but no action wasWebster’s New Collegiate Dictionary, an acute stage occursacutewhen a symptom “demands urgent attention.” Whether the acutesymptom emerges suddenly or is a transformation of a prodromalstage, an immediate action is required. Diverting funds and other resources to this emerging situation may cause disequilibrium and disturbance in the whole system. It is onlythose organizations that have already prepared a framework forthese crises that can sustain their normal operations. For example, the US public roads and bridges have for a long time reflected a prodromal stage of crisis awareness by showing cracks and occasionally a collapse. It is perhaps in light of the obsessive decision to balance the Federal budget that reacting to the problem has been delayed and ignored. This situation has entered an acute stage and at the time of this writing, it was reported that a bridge in Maryland had just collapsed.The reason why prodromes are so important to catch is thatit is much easier to manage a crisis in this stage. In the caseof most crises, it is much easier and more reliable to take careof the problem before it becomes acute, before it erupts and causes possible complications (Darling et al., 1996). In andamage. However, the losses are incurred. Intel, the largest producer of computer chips in the USA, had to pay an expensiveprice for initially refusing to recall computer chips that proved unreliable o n on certain calculations. The f irmfirm attempted to play the issue down and later learned its lesson. At an acutestage, when accusations were made that the Pentium Chips were not as fast as they claimed, Intel quickly admitted the problem,apologized for it, and set about fixing it (Mitroff et al., 1996). Chronic crisis stageDuring this stage, the symptoms are quite evident and always present. I t isIt is a period of “make or break.” Being the third stage, chronic problems may prompt the company’s management to once and for all do something about the situation. It may be the beginning of recovery for some firms, and a deathknell for others. For example, the Chrysler Corporation was only marginallysuccessful throughout the 1970s. It was not, however, until the company was nearly bankrupt that amanagement shake-out occurred. The drawback at the chronic stage is that, like in a human patient, the company may get used to “quick fixes” and “band “band--aid”approaches. After all, the ailment, the problem and the crisis have become an integral partoverwhelmed by prodromal and acute problems that no time or attention is paid to the chronic problems, or the managers perceive the situation to be tolerable, thus putting the crisison a back burner.Crisis resolutionCrises could be detected at various stages of their development. Since the existing symptoms may be related todifferent problems or crises, there is a great possibility thatthey may be misinterpreted. Therefore, the people in charge maybelieve they have resolved the problem. However, in practicethe symptom is often neglected. In such situations, the symptomwill offer another chance for resolution when it becomes acute,thereby demanding urgent care. Studies indicate that today anincreasing number of companies are issue-oriented and searchfor symptoms. Nevertheless, the lack of experience in resolvinga situation and/or inappropriate handling of a crisis can leadto a chronic stage. Of course, there is this last opportunityto resolve the crisis at the chronic stage. No attempt to resolve the crisis, or improper resolution, can lead to grim consequences that will ultimately plague the organization or even destroy it.It must be noted that an unsolved crisis may not destroy the company. But, its weakening effects can ripple through the organization and create a host of other complications.Preventive effortsThe heart of the resolution of a crisis is in the preventiveefforts the company has initiated. This step, similar to a humanbody, is actually the least expensive, but quite often the mostoverlooked. Preventive measures deal with sensing potential problems (Gonzales-Herrero and Pratt, 1995). Major internalfunctions of a company such as finance, production, procurement, operations, marketing and human resources are sensitive to thesocio-economic, political-legal, competitive, technological, demographic, global and ethical factors of the external environment. What is imminently more sensible and much more manageable, is to identify the processes necessary forassessing and dealing with future crises as they arise (Jacksonand Schantz, 1993). At the core of this process are appropriate information systems, planning procedures, anddecision-making techniques. A soundly-based information system will scan the environment, gather appropriate data, interpret this data into opportunities and challenges, and provide a concretefoundation for strategies that could function as much to avoid crises as to intervene and resolve them.Preventive efforts, as stated before, require preparations before any crisis symptoms set in. Generally strategic forecasting, contingency planning, issues analysis, and scenario analysis help to provide a framework that could be used in avoiding and encountering crises.出处:出处:Toby TobyJ.

The New Public Management SituationOwen E. HughesMonash University Management (Australia)No doubt, many countries in the world, and both developed countries and developing countries, in the late 1980s and early 1990s began a continuous public sector management reform movement. The reform movement is still in many aspects government continue to the organization and management of the influence. People in these reforms view repudiating them. Critics especially in Britain and the United States, critics say the new mode of various problems exist, but also does not have the international prevailing reform of public management, could not be called paradigm. Criticism from almost every aspect of the change. Most of the academic criticism belong to the mouth. Different schools of thought in detail discussion, The academic journal articles and abstraction, from reality. At the same time, in the practice of public management and implementation of the reform and the change. As I in other articles in the thought, in most countries, the traditional public administrative mode for public management mode has been replaced. The reform of public department responded to the realities of several interrelated problems, including: the function of public sector provide public services of low efficiency, Economic theory of change, Private sector related changes impact of globalization, especially as a kind of economic power, Technology changes made decentralization and better control globally becomes possible. The administrative management can be divided into three stages: the development of distinct phases, and public administration before traditional pattern and public management reform stage. Each stage has its own management mode. From a stage of transition to the next stage is not easy, from the traditional public administration to public administration has not yet completed the transition. But it was only a matter of time. Because the new mode of theoretical basis is very strong. The new public management movement ", "although this name, but it is not only a debate in the booming, and in most developed countries have taken the best management mode of expression. The traditional administrative mode than it's age is a great reform, but that time has passed.A traditional patternObviously, in the late 19th century bureaucracy system theory, not sound already exists some form of administrative management. Public administration has a long history, and it is the concept of a government and the rise of civilization as history. As the case Glad2den Osama bin laden (point), a model of administrative since the government appears has existed. First is endowed with founder or leader, then is the social or administrative person to organizers of eternity. Administration management or business is all in social activities, although not among factors, but the glow of social sustainable development is of vital importance. Recognized administrative system in ancient Egypt is already exists, its jurisdiction from the Nile flooding caused by the year to build the pyramids irrigation affairs. China is adopted in the han dynasty, Confucian norms that government should be elected, not according to the background, but according to the character and ability, the government's main goal is to seek the welfare of the people. In Europe, various empire - Greek, Roman, and the holy Roman, Spain's administrative empire, they first by the central through various rules and procedures. Weber's thought, "modern" medieval countries develop simultaneously with "bureaucratic management structure development". Although these countries in different ways, but they have common features, it can be called before modern. Namely, the administrative system of early essence is the personification of, or the establishment in Max Weber's "nepotism" basis, i.e. to loyal to the king or minister certain human foundation, not is personified, With allegiance to the organization or individual basis rather than for the foundation. Although there are such a viewpoint that administration itself not only praise from traditional mode, the characteristic of early but often leads to seek personal interests corruption or abuse of power. In the early administrative system, we now feel very strange approach has the functions of government administration is generally behavior. All those who walk official tend to rely on friends or relatives for work or buy officer, which means the money to buy the first officer or tax officials, and then out to the customer to money, which is the first to buy officer recovery investment cost, and can make a fortune. America in the 19th century FenFei system of "political parties" means in the ruling changed at the same time, the government of all administrative position is changed. Modern bureaucracy is before "personal,traditional, diffusion and similar and special", and according to the argument, modern Weber bureaucracy is "impersonal, rational, concrete, achievement orientation and common". Personalized government is often inefficient: nepotism means incompetent not capable person was arranged to positions of leadership, FenFei political corruption, in addition to making often still exist serious low efficiency. The enormous success of traditional administrative pattern that early practice looks strange. Specialization and not politicized administrative in our opinion is so difficult to imagine that trace, there exist other system. Western administrative system even simple selection of officials to pass the exam, until 1854, Britain and north G..M. Trevelyan report after Northcote - began to establish in China, although the system has long passage.The traditional public administrative patternIn the late 19th century, additionally one kind of pattern on the world popular, this is the so-called traditional administrative pattern. Its main theoretical basis from several countries, namely, the American scholars and Germany Woodrow Wilson of Max Weber's, people put their associated with bureaucracy model, Frederick Tyler systematically elaborated the scientific management theory, the theory of the private sector from America, for public administration method was provided. And the other theorists, Taylor without focusing on public sector, but his theory was influential in this field. The three traditional public administration mode is theorist of main effect. In other countries, plus G..M. Trevelyan and North America, the state administration of administrative system, especially the Wilson has produced important influence. In the 19th century, the north G..M. Trevelyan and put forward through the examination and character, and appointed officials put forward bias and administrative neutral point of view. The traditional administrative pattern has the following features:1. The bureaucracy. The government shall, according to the principle of bureaucratic rank and organization. The German sociologist Max Weber bureaucracy system of a classic, and analysis. Although the bureaucracy in business organizations and other tissues, but it is in the public sector got better and longer.2. The best way of working and procedures are in full manual detail codes, for administrativepersonnel to follow. Strictly abide by these principles will run for the organization provides the best way.3. Bureaucratic service. Once the government policy areas in, it will be through the bureaucracy to provide public products and service providers.4. In political and administrative two relations, political and administrative managers generally think of administrative affairs can be separated. Administration is the implement instruction, and any matter policy or strategic affairs shall be decided by the political leaders, which can ensure that the democratic system.5. Public interests are assumed to individual civil servants, the only motive for public service is selfless paying.6. Professional bureaucracy. Public administration is viewed as a kind of special activities, thus requirements, obscure, civil servants neutral equal employment and lifelong service to any political leaders.7. The administrative task is to carry out the meaning of the written instructions and not others assume the personal responsibility.Through the comparison of the early administrative pattern, we can better understand the main advantages and Webber system differences. Webber system and it is the most important mode of various before the difference: the rule-based impersonal system replaced the personification of administrative management system. An organization and its rules than any of the people are important organization. Bureaucracy is its operation and how to respond to customer must is personified. As Weber has demonstrated that the modern office management ", will be incorporated into various regulations deeply touched it. The modern public administration by law theory, to command certain affairs authority has been awarded the legitimate public authority. This does not grant an institution specific cases through some instructions. It only matters is abstractly control some issues. In contrast, through personal privileges and give concession regulation of all affairs. The latter is completely dominated by the hereditary system, at least these affairs is not the traditional infringement is this situation." It is very important. Early administration based on personal relationships, be loyal to relatives, protect, leaders or political, rather than on the system. Sometimes, the early administration ispolitically sensitive, because of the administrative organs of the staff is appointed, they also politicians arms or mainstream class. However, it is often autocratic, autocratic administration may be unfair, especially for those who can't or unwilling to input personal and political game. One of the basic principles for with weber impersonal system to completely eliminate autocratic - at least in ideal condition is so. File exists, the reference principle of parallel and legal basis in the same environment means will always make the same decision. Below this kind of circumstance is not only more efficient, and the citizen and bureaucratic hierarchy know myself.Other differences were associated with this. In various regulations and impersonal basis, will naturally formed strict hierarchy. Personal rating system and its provisions in the left unchanged. Although Webber emphasizes the entire system, but he also noticed the bureaucracy of the organization and individual term.The traditional administrative mode won great success, it is widely adopted by governments around the world. Theoretically or in practice, it shows the advantage. And before the corruption flourished, it is more efficient than system, and the thought of individual professionalization civil servants and amateur service has a great progress. However, this model is also exposed the problems that shows that the model can even said outdated, also can say is outdated.The theory of public administration has been difficult to describe the pillar. Political control theory has problems. Administrative means follow instructions, so people demand a well-ordered transceiver method. Instruction between implementers and has a clear division. But this is not the reality, and with the public service domain expands the scale and more impossible. The traditional mode of another theoretical pillar - bureaucracy theory is no longer considered particularly effective form of organization. Formal bureaucracy could have its advantages, but people think it often training to routineer and innovators, Encourage executives rather than risk aversion risk-taking, encourage them to waste instead of effective use of scarce resources. Webb was the bureaucracy is regarded as an ideal type ", "but now this ideal type is inert, cultivate the progressive, leads to low efficiency, these mediocrity and is believed to be the public sector of the special disease. It is also criticized. Actually, theword "bureaucracy in today's more likely as low efficiency of synonyms.The new public management modeIn the 1980s, the public sector is a traditional administrative pattern of new management methods of defects. This method can alleviate some of the problems of traditional pattern, also means that the public sector operation aspects has changed significantly. The new management method has many names: management of "individualism", "the new public administration", based on the market of public administration ", after the bureaucracy model "or" entrepreneurial government ". To the late 1990s, people tend to use "and the concept of new public administration".Although the new public management, but for many of the names of public management of department of actual changes happened, people still have a consensus. First, no matter what, it is called mode with traditional represents a significant change of public administration, different more attention and managers of the individual responsibility. Second, it is clear to get rid of the classical bureaucracy, thereby organization, personnel, term and conditions more flexible. Third, it stipulates the organization and personnel, and it can target according to the performance indicators measuring task completion. Also, to plan the assessment system for more than ever before, and also can be more strictly determine whether the government plans to achieve its objectives. Fourth, the senior executives are more likely to color with political government work, rather than independent or neutral. Fifth, the more likely the inspection by the market, buyers of public service provider and distinguish "helmsman, with the rower to distinguish". Government intervention is not always refers to the government by means of bureaucracy.
