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)。
命名[编辑]这种滤波方法以它的发明者鲁道夫.E.卡尔曼(Rudolph E. Kalman)命名,但是根据文献可知实际上Peter Swerling在更早之前就提出了一种类似的算法。
斯坦利。
施密特(Stanley Schmidt)首次实现了卡尔曼滤波器。
卡尔曼在NASA埃姆斯研究中心访问时,发现他的方法对于解决阿波罗计划的轨道预测很有用,后来阿波罗飞船的导航电脑便使用了这种滤波器。
关于这种滤波器的论文由Swerling(1958)、Kalman (1960)与Kalman and Bucy(1961)发表。
目前,卡尔曼滤波已经有很多不同的实现。
卡尔曼最初提出的形式现在一般称为简单卡尔曼滤波器。
除此以外,还有施密特扩展滤波器、信息滤波器以及很多Bierman, Thornton开发的平方根滤波器的变种。
也许最常见的卡尔曼滤波器是锁相环,它在收音机、计算机和几乎任何视频或通讯设备中广泛存在。
以下的讨论需要线性代数以及概率论的一般知识。
卡尔曼滤波建立在线性代数和隐马尔可夫模型(hidden Markov model)上。
其基本动态系统可以用一个马尔可夫链表示,该马尔可夫链建立在一个被高斯噪声(即正态分布的噪声)干扰的线性算子上的。

1引言在商业界,有越来越多关于政治关联的影响的经济研究。
它们发现政治关联能够帮助企业确保有利的规章条件以及成功获得资源,比如能够最终提高企业价值或是提升绩效的银行贷款,这种政治关联的影响在不同的经济条件下呈现不同的效果。
在高腐败和法律制度薄弱的国家,政治关联对企业价值具有决定性因素1的作用.中国由高度集权的计划经济向市场经济转变,政府对市场具有较强的控制作用,而且有大量的上市企业具有政治关联。
中小型企业发展的很迅速,他们已经在全球经济环境中变得越来越重要。
从90年代起, 政治因素对中国的任何规模的企业来说都变得越来越重要,尤其是中小型企业的价值。
和其他的部门相比较,中小型企业只有较小的现金流,不稳定的现金流且高负债率.一方面,中小型企业改变更加灵活;另一方面,中小型企业在由于企业规模以及对银行来说没有可以抵押的资产,在筹资方面较为困难。
企业如何应对微观经济环境和政策去保证正常的企业活动,并且政治关联如何影响企业价值?这篇论文调查政治关联和企业价值之间的联系,并且试图去研究企业是否可以从政治关联中获利提升企业价值。
2.2定义这些中小型企业之所以叫中小型企业,是和管理规模有关。
对这些小企业来说,雇员很少,营业额较低,资金一般由较少的人提供,因此,通常由这些业主直接管理企业。

当一国的经济增长的可持续性岌岌可危的时候,金融业的改革一直被认为是提高资金使用效率和消费型经济增长重新走向平衡的必要(Lardy,1998年,Prasad,2007年)。
事实上,不久前,中国的国有银行被视为“技术上破产”,它们的生存需要依靠充裕的国家流动资金。
但是,在银行改革开展以来,最近,强劲的盈利能力已恢复到国有商业银行的水平。
但自从中国的国有银行在不久之前已经走上了改革的道路,它可能过早宣布银行业的改革尚未取得完全的胜利。
此外,其坚实的财务表现虽然强劲,但不可持续增长。
随着经济增长在2008年全球经济衰退得带动下已经开始软化,银行预计将在一个比以前更加困难的经济形势下探索。
本文的目的不是要评价银行业改革对银行业绩的影响,这在一个完整的信贷周期后更好解决。
相反,我们的目标是通过审查改革的进展和银行改革战略,并分析其近期改革后的强劲的财务表现,但是这不能完全从迄今所进行的改革努力分离。
本文有三个部分。
在第二节中,我们回顾了中国的大型国有银行改革的战略,以及其执行情况,这是中国银行业改革的主要目标。
第三节中分析了2007年的财务表现集中在那些在市场上拥有浮动股份的四大国有商业银行:中国工商银行(工商银行),中国建设银行(建行),对中国银行(中银)和交通银行(交通银行)。
引人注目的是中国农业银行,它仍然处于重组上市过程中得适当时候的后期。

By phase-shifting technique, we have obtained information of the object wave spreading to a certain distance from the original object. Therefore, in order to get the information of the object wave at its initial spreading position, what we need to do is a reverse work.Fig.1 Geometric coordinate of digital holographyexact registering distance.The focusing functions normally applied can be divided into four types: gray and gradient function, frequency-domain function, informatics function and statistics function. Gray evaluation function is easy to calculate and also robust. It can satisfy the demand of common focusing precision. We apply the intensity sum of reconstruction image as the evaluation function:min ),(11==∑∑==M k Nl l k SThe calculation is described in Fig.2. The position occurring the turning point correspondes to the best registration distanced, also equals to the reconstructing distance d '.It should be indicated that if we only need to reconstruct the phase map of the object wave, the registration distance substituted into the calculation equation is permitted having a departure from its true value.4 Spatial resolution of digital holography4.1 Affecting factors of the spatial resolution of digital holographyIt should be considered in three respects: (1) sizes of the object and the registering material, and the direction of the reference beam, (2) resolution of the registering material, and (3) diffraction limitation.For pointx2on the object shown in Fig.3, the limits of spatial frequency are λξθλθθ⎥⎦⎤⎢⎣⎡⎪⎪⎭⎫ ⎝⎛-'-=-=-0211maxmax tan sin sin sin sin z x f R R Fig.2 Determining reconstructing distanceλξθλθθ⎥⎦⎤⎢⎣⎡⎪⎪⎭⎫ ⎝⎛-'-=-=-0211minmin tan sin sin sin sin z x f R R Frequency range isλξξ⎥⎦⎤⎢⎣⎡⎪⎪⎭⎫ ⎝⎛-'-⎥⎦⎤⎢⎣⎡⎪⎪⎭⎫ ⎝⎛-=∆--02110211tan sin tan sin z x z x f so the range is unrelated to the reference beam.Considering the resolution of registering material in order to satisfy the sampling theory, phase difference between adjacent points on the recording plate should be less than π, namely resolution of the registration material.c f f f =∆η21)(min max 4.2 Expanding the spatial resolution of reconstruction imageExpanding the spatial resolution can be realized at least in three ways: (1) Reducing the registration distance z 0 can improve the reconstruction resolution, but it goes with reduction of the reconstruction area at the same ratio.Therefore, this method has its limitation. (2) Increasing the resolution and the imaging size of CCD with expensive price. (3) Applying image-synthesizing technique [11]CCD captures a few of images between which there is small displacement (usually a fraction of the pixel size) vertical to the CCD plane, shown in Fig.4(Schematic of vertical moving is the same).This method has two disadvantages. First, it is unsuitable for dynamic testing and can only be applied in the static image reconstruction. Second, because the pixel size is small (usually 5μm to 10μm) and the displacement should a fraction of this size (for example 2μm), it needs a moving table with high resolution and precision. Also it needs high stability in whole testing.In general, improvement of the spatial resolution of digital reconstruction isFig.3 Relationship between object and CCDstill a big problem for the application of digital holography.Fig.4 Image capturing by moving CCD along horizontal direction5 Testing resultsFig.5 is the photo of the testing system. The paper does testing on two coins. The pixel size of the CCD is 4.65μm and there are 1 392×1 040 pixels. The firstis one Yuan coin of RMB (525 mm) used for image reconstruction by phase-shifting digital holography. The second is one Jiao coin of RMB (520 mm) for the testing of deformation measurement also by phase-shifting digital holography.Fig.5 Photo of the testing system5.1 Result of image reconstructionThe dimension of the one Yuancoin is 25 mm. The registrationdistance measured by ruler isabout 385mm. We capture ourphase-shifting holograms andreconstruct the image byphase-shifting digital holography.Fig.6 is the reconstructed image.Fig.7 is the curve of the auto-focusfunction, from which we determine the real registration distance 370 mm. We can also change the controlling precision, for example 5mm, 0.1 mm,etc., to get more course or precision reconstruction position.Fig.6 Reconstructed image Fig.7 Auto-focus function5.2 Deformation measurementIn digital holography, the method of measuring deformation measurement differs from the traditional holography. It gets object wave before and after deformation and then subtract their phases to obtain the deformation. The study tested effect of heating deformation on the coin of one Jiao. The results are shown in Fig.8, Where (a) is the interferential signal of the object waves before and after deformation, and (b) is the wrapped phase difference.Fig.8 Heating deformation results5.3 Improving the spatial resolutionFor the tested coin, we applied four sub-low-resolution holograms to reconstruct the high-resolution by the image-synthesizing technique. Fig.9 (a) is the reconstructed image by one low-resolution hologram, and (b) is the high-resolution image reconstructed from four low-resolution holograms.Fig.9 Comparing between the low and high resolution reconstructed image6 SummaryDigital holography can obtain phase and amplitude of the object wave at the same time. Compared to other techniques is a big advantage. Phase-shifting digital holography can realize image reconstruction and deformation with less noise. But it is unsuitable for dynamic testing. Applying the intensity sum of the reconstruction image as the auto-focusing function to evaluate the registering distance is easy, and computation is fast. Its precision is also sufficient. The image-synthesizing technique can improve spatial resolution of digital holography, but its static characteristic reduces its practicability. The limited dimension and too big pixel size are still the main obstacles for widely application of digital holography.外文文献译文:标题:图像重建中的相移数字全息摘要:相移数字全息术被用来研究研究艺术品的内部缺陷。

Analysis on the Chinese Enterprise Financing Abstract:The main sources of financing for small and medium sized enterprises (SMEs) are equity, trade credit paid on time, long and short term bank credits, delayed payment on trade credit a nd other debt. The marginal costs of each financing instrument are driven by asymmetric informatio n and transactions costs associated with nonpayment. According to the Pecking Order Theory, firms will choose the cheapest source in terms of cost. In the case of the static trade-off theory, firms cho ose finance so that the marginal costs across financing sources are all equal, thus an additional Euro of financing is obtained from all the sources whereas under the Pecking Order Theory the source is determined by how far down the Pecking Order the firm is presently located. In this paper, we argue that both of these theories miss the point that the marginal costs are dependent of the use of the fun ds, and the asset side of the balance sheet primarily determines the financing source for an additiona l Euro. An empirical analysis on a unique dataset of Portuguese SMEs confirms that the compositio n of the asset side of the balance sheet has an impact of the type of financing used and the Pecking Order Theory and the traditional Static Trade-off theory are rejected.For SME the main sources of financing are equity (internally generated cash), trade credit, ban k credit and other debt. The choice of financing is driven by the costs of the sources which is primar ily determined by costs of solving the asymmetric information problem and the expected costs assoc iated with non-payment of debt. Asymmetric information costs arise from collecting and analysing i nformation to support the decision of extending credit, and the non-payment costs are from collectin g the collateral and selling it to recover the debt. Since SMEs’ management and shareholders are oft en the same person, equity and internally generated funds have no asymmetric information costs and equity is therefore the cheapest source.1 Asset side theory of SME financingIn the previous section we have suggested that SME’s in Portugal are financed using internal g enerated cash, cheap trade credits, long and short-term bank loans and expensive trade credits and o ther loans. In this section the motives behind the different types of financing are discussed.1.1 Cheap Trade creditsThe first external financing source we will discuss is trade-credits. Trade credits are interestingsince they represent financial services provided by non-financial firms in competition with financia l intermediaries. The early research within this area focused on the role of trade credits in relation to the credit channel or the so called “Meltzer” effect and in relation to the efficiency of monetary poli cy. The basic idea is that firms with direct access to financial markets, in general large well known f irms, issue trade credits to small financially constrained firms . The more recent research breaks the role of trade credits into a strategic motive and financial motive for issuing and using these credits.Strategic motivesThe first theory centers on asymmetric information regarding the firm’s products. Trade credits are offered to the buyers so that the buyer can verify the quantity and quality before submitting pay ments. By offering trade finance the supplier signals to the buyers that they offer products of good q uality. Since small firms, in general, have no reputation then these firms are forced to use trade credi ts to signal the quality of their products. The use of trade credits is therefore driven by asymmetric i nformation of the products and is therefore more likely to be used by small firms, if the buyer has lit tle information about the supplier, or the products are complicated and it is difficult to asses their qu ality.The second strategic motive is pricing. Offering trade finance on favorable terms is the same as a price reduction for the goods. Thus firms can use trade credits to promote sales without officially reducing prices or use them as a tool for price discrimination between different buyers. Trade credit s are most advantageous to risky borrowers since their costs of alternative financing are higher than for borrowers with good credit ratings. Thus trade credits can be used as tool for direct price discrim ination but also as an indirect tool (if all buyers are offered the same terms) in favor of borrowers wi th a low credit standing.Trade credits are also used to develop long term relationships between the supplier and the bu yers. This often manifests itself by the supplier extending the credit period in case the buyer has tem porary financial difficulties. Compared to financial institutions suppliers have better knowledge of t he industry and are therefore better able to judge whether the firm has temporary problems or the pr oblems are of a more permanent nature.The last motive in not strictly a strategic motive but is based on transactions costs. Trade credit s are an efficient way of performing the transactions since it is possible to separate between delivery and payment. In basic terms the truck driver delivering the goods does not have to run around to find the person responsible for paying the bills. The buyer also saves transactions costs by reducing the amount of cash required on“hand” .Financing motivesThe basis for this view is that firms compete with financial institutions in offering credit to oth er firms. The traditional view of financial institutions is that they extend credit to firms where asym metric information is a major problem. Financial institutions have advantages in collecting and anal yzing information from, in particular, smaller and medium sized firms that suffer from problems of asymmetric information. The key to this advantage over financial markets lies in the close relations hip between the bank and the firm and in the payment function. The financial institution is able to m onitor the cash inflow and outflows of the firm by monitoring the accounts of the firm.But with trade credits non-financial firms are competing with financial institutions in solving t hese problems and extending credit. How can non-financial institutions compete in this market? Pet ersen and Rajan [1997] briefly discusses several ways that suppliers may have advantages over fina ncial institutions. The supplier has a close working association with the borrower and more frequent ly visits the premises than a financial institution does. The size and timing of the lenders orders with the supplier provides information about the conditions of the borrowers business. Notice that this in formation is available to the supplier before it is available to the financial institution since the financ ial institution has to wait for the cash flow associated with the orders. The use of early payment disc ounts provides the supplier with an indication of problems with creditworthiness in the firm. Again t he supplier obtains the information before the financial institution does. Thus the supplier may be a ble to obtain information about the creditworthiness faster and cheaper than the financial institution.The supplier may also have advantages in collecting payments. If the supplier has at least a loc al monopoly for the goods then the ability to withhold future deliveries is a powerful incentive for t he firm to pay. This is a particular powerful threat if the borrower only accounts for a small fraction of the suppliers business. In case of defaults the supplier can seize the goods and in general has a be tter use for them than a financial intermediary sizing the same goods. Through its sales network the supplier can sell the reclaimed goods faster and at a higher price than what is available to a financial intermediary. These advantages, of course, depend on the durability of the goods and how much the borrower has transformed them.If asymmetric information is one of the driving forces the explanation of trade credits then firms can use the fact that their suppliers have issued them credits in order to obtain additional credit f rom the banks. The banks are aware that the supplier has better information thus the bank can use tr ade credits as signal of the credit worthiness of the firm.That trade credits are in general secured by the goods delivered also puts a limit on the amount of trade credits the firm can obtain, thus the firm cannot use trade credits to finance the entire operat ions of the firm.In summary the prediction is that the level of asymmetric information isrelatively low between the providers of trade credit and the borrowers due to the issuer’s general knowledge of the firm and the industry. In the empirical work below the variables explaining the use of trade credit are credit r isk factors and Cost of Goods Sold. Since these trade credits are secured by the materials delivered t o the firm, firms cannot “borrow” for more than the delivery value of the goods and services.1.2 Bank loansBanks have less information than providers of trade credit and the costs of gathering informati on are also higher for banks than for providers of trade credit. Providers of trade credits also have a n advantage over banks in selling the collateral they have themselves delivered, but due to their size and number of transactions banks have an advantage in selling general collateral such as buildings, machinery etc. Banks therefore prefer to issue loans using tangible assets as collateral, also due to a symmetric information, they are less likely to issue loans to more opaque firms such as small and hi gh growth firms. Banks are therefore willing to lend long term provided that tangible assets are avai lable for collateral. In the empirical work below tangible assets and credit risk variables are expecte d to explain the use of long-term bank loans and the amount of long-term bank loans are limited by the value of tangible assets.The basis for issuing Short Term Bank Loans is the comparative advantages banks have in eval uating and collecting on accounts receivables, i.e. Debtors. It is also possible to use Cash and Cash equivalents as collateral but banks do not have any comparative advantages over other providers of credit in terms of evaluating and collecting these since they consist of cash and marketable securitie s. In terms of inventories, again banks do not have any comparative advantages in evaluating these. Thus, we expect the amounts of debtors to be the key variable in explaining the behaviour of Short Term Bank Loans.1.3 Expensive trade credit and other loansAfter other sources of finance have been exhausted firms can delay payment on their trade cred its. However, this is expensive since it involves giving up the discount and maybe incurs penalty pa yments. Also the use of this type of credit can have reputational costs and it may be difficult to obtai n trade credit in the future. The nature of the costs, of course, depends on the number of suppliers, if there is only one supplier then these costs can be rather high whereas if the firm can obtain the sam e goods and services from other suppliers then these costs are not particularly high.Other debt is composed of credit card debt, car loans etc. that are dearer than bank loans. Again , the variables determining this type of debt are financial health and performance. Below, however, we do not have any good information regarding these types of loans and what they consists of thus we pay little attention to them in the empirical work.ConclusionsCurrently there exist two theories of capital structure The Pecking Order Theory where firms fi rst exhaust all funding of the cheapest source first, then the second cheapest source and so on. The d ifferences in funding costs are due to adverse selection costs from asymmetric information. The sec ond theory is the Tradeoff .Theory where firms increase the amount of debt as long as the benefits are greater than the costs from doing so. The benefits of debt are tax-shields and “positive agency c osts” and the costs of debt are the expected bankruptcy costs and the “negative agency costs”. In bot h of these theories, the composition of the asset side of the balance sheet is not important and in this paper, that proposition is strongly rejected. So the main conclusion is that the composition of the as set side of the balance sheet influences the composition of the liability side of the balance sheet in te rms of the different types of debt used to finance the firm, or that the use of the funds is important in deciding the type of financing available.We further argue that it is asymmetric information and collateral that determines the relationshi p between the asset side and liability side of the balance sheet. The theory works reasonable well for Cheap Trade Credits and Long Term Bank Loans but the tests for Short Term Bank Loans are disap pointing.Source: Jan Bartholdy, Cesario Mateus, “Financing of SMEs”.London businessreview. 2007(9).pp.43-45中国企业融资分析摘要:中小企业融资的主要来源有:股权融资、按时兑现的贸易信贷融资、中长期银行信贷融资、延迟兑现的贸易信贷融资以及其他债务融资,每种融资方式的边际成本取决于与其滞纳金相关的信息不对称成本和交易成本。
