Abstract

Purpose –The purpose of this paper is to explore the networking effects of venture capital (VC)?rms on portfolio companies.VCs can bring speci?c skills and abilities to their ongoing relationships with their portfolio companies and thus add value by in?uencing key portfolio company operations.High levels of engagement also translate into giving advice and support,helping with the team culture,creating strategic alliances,or exercising corporate governance.A particular mechanism through which these support services are delivered is syndication investment.

Design/methodology/approach –Using network theory tools the paper investigates the effects of syndication on VC ?rm performance.

Findings –The paper ?nds that networked VC ?rms are better placed to bene?t from their investments.

Originality/value –The paper sheds light on the importance of network relationships in the venture capital industry.

Introduction

Networks may be seen as an alternative to banks as intermediaries in credit markets.They may also coordinate disperse resources in factor and product https://www.360docs.net/doc/5d1446862.html,works’role in the allocation of scarce resources has been recognized both in the past and today (Cornelli and Goldreich,2001;Ljungqvist et al.,2005).As an organizational form a network is distinct from both a ?rm and a market,as they are not limited by speci?c contracts to some ultimate owner of property rights,nor are they engaged in a bargaining process,having to bid for https://www.360docs.net/doc/5d1446862.html,works are rather cooperative mechanisms that arrive at allocative decisions by consensus and through the pooling of relevant information.

In the venture capital (VC)industry,networks abound.A central feature of venture capital is the way it allows investment ?rms to syndicate their investments –when two or more ?rms jointly undertake a new project (Lerner,1994).Syndication inevitably creates a multitude of relationships spanning the syndicate member’s coordination and various service providers,including research anddevelopment organizations,patent lawyers,headhunters,investment bankers etc.(Gorman and Sahlman,1989;Sahlman,1990).The diverse sets of relationships with different agents (e.g.investors,co-investors,suppliers,customers)imply large variations in the quality and support offered to portfolio companies.It is likely that these differences in investment and engagement approach will also affect VC syndicate performance.

VC ?rms operate in uncertain environments.The uncertainties are often linked to the risk involved in product development and commercialization.For instance,risks faced by start-up companies have their roots in both the external environment and in lack of capabilities within the organization.There may be sudden market changes and shifts in investor and consumer expectations,compelling the company to completely change the course of its https://www.360docs.net/doc/5d1446862.html,panies may also face shortage of personnel or key physical and organizational resources to carry out a new development opportunity successfully.VC literature has argued that by syndicating investments companies are able to effectively deal with all such risks and uncertainties.

Prior literature on networks has primarily been concerned with identifying their existence in various ?nancial markets.An important issue is the likely impact of this particular form of organizational structure on VC ?rm performance.To this end,VC network measures of how well networked a VC is will need to be developed.Recently,there has been a surge of interest in networking theory,which freely borrows its main tools of analysis from Graph theory (Hochberg et al.,2006).In the present context,we use the graph theory based measurement tools to capture the following different aspects of a VC ?rm’s in?uence:(i)the number of VCs with which it has a relationship as a proxy for information about deal ?ow,expertise,contacts,and pools of capital it has access to;(ii)its access to the best-connected VCs;and (iii)its ability to act as an intermediary,bringing together VCs with complementary skills or investment opportunities that lack a direct relationship.As the prevailing practice of syndication investment underlines VC ?rms greatly bene?t from having a multitudes of relationships.Our results show that the bene?ts from these relationships are magni?ed when VC ?rms join hands with other well-connected VC ?rms.

The paper is organized as follows.The next section provides a survey of the prior literature on VC ?rm engagement practices.This section also develops VC speci?c network theory measures.We then discuss our data and provide variable de?nitions,which is followed by our report of results.We establish empirical implications for the system of VC networked relations,including the impact of various measures of networks on VC ?rm performance.In the ?nal section,we conclude and discuss the research’s implications.

Literature survey

The evolution of interdependencies between different organizational tasks is a manifestation of how linkages between different actors play a critical role in enterprise development.To better understand the increasingly complex relationships among organizations,which often arise,as we pointed out above,as a result of their uncertain market environments (Kenis and Knoke,2002;Provan and Sebastian,1998),researchers have often resorted to analysing resources and capabilities as catalysts for interorganizational relations.Such an approach is often couched as the resource-based view of the ?rm (Barney,1991;Wernerfelt,1984).Although this approach recognizes the role of unique ?rm history and speci?c nature of capabilities,it pays scant attention to network ‘complementarities’that motivate ?rms’participation in inter?rm networks.It is important to note that inter?rm networks can be useful in this framework as they channel valuable information about the resource advantage (e.g.key information,useful contacts,capital)that can be obtained from ?rm network resources.

Prior literature on syndication has generally focused on ex-anti motives of VC?rms, namely how syndication may improve the selection process through improved screening,due diligence and decision-making.Following traditional?nance theory, syndication is considered as a means by which VC?rms secure a well-diversi?ed portfolio,enabling the VC?rm to reduce the unsystematic risk of the portfolio.There are also expectations of reciprocity and better future?nancial deals when VC?rms are able to syndicate with other reputable?rms.

For a number of reasons,determining the ex-post motives of syndication,especially how investors can share their complementary skills or speci?c knowledge,and as a result,add value to a portfolio company is also important(Bygrave,1988).The management of the ex-post investment may signi?cantly affect its performance. Brander et al.(2002)compared Canadian-syndicated VC deals with stand-alone projects and found that the need to access speci?c resources from the ex-post management of investment,rather than for the selection of investment resulted in the syndication of projects which also enjoyed higher rate of returns than stand-alone projects.The study of such investments provides an opportunity to examine the key factors driving the VC?rm performance.

Network methodology

Network analysis is conducted at various levels of social interaction.One can either analyse clusters(networks)of organizations and their patterns of interaction,involving a study of the complete network or focus solely upon one or more speci?c operations in a network(Powell,1990;Burt,1992;Powell et al.,1996).Within the?eld of business studies,one common practice is to take the?rm as a unit of analysis and examine the links or ties it is able to build with actors outside the?rm.This helps to understand how the?rm develops and operates a network(Birley,1985;Aldrich and Zimmer,1986; Dubini and Aldrich,1991;Larson,1992).Notwithstanding the fact that counting the number of ties a?rm has established provides important insights into its network size, the various dimensions of a network and/or the way they in?uence the development of a new business is also a key question in network analysis(Chu,1996).For example, questions such as how socio-economic contexts in which actors operate are linked to strategic networks have not yet been fully explored.

The social network model of organization formation(Granovetter,1973,1985; Aldrich and Zimmer,1986;Dubini and Aldrich,1991;Burt,1992;Larson,1992)views new organizations as created by entrepreneurs“embedded”(Granovetter,1985)in a series of network relationships.Speci?cally,the pattern and process through which network relationships are developed and maintained are the main areas of research interest.Dubini and Aldrich(1991)de?ne a network as“patterned relationships between individuals,groups,and organizations”.This suggests that a network consists of structure and content(Burt,1992),where structure is the pattern by which individuals and organisations are linked,including interaction frequency and the ways in which they are connected(e.g.by contracts,equity,kinship,etc.),while content describes the resources exchanged within networks.

Network size

Extant literature examines the structure of organizational networks in terms of size and strength(Dubini and Aldrich,1991).There are many ways in which network size

is analysed.A common approach is to study the number of ties or links between an organization and outside contacts.In this respect,one can usefully distinguish between a “personal”network,i.e.“those persons with whom an entrepreneur has direct relations and an ‘extended’network”,i.e.relationships between an organization and the external world (Dubini and Aldrich,1991).A related distinction is between the actor’s direct “personal”links and “total”links which cover direct and indirect links –Shulman (1976)“anchorage”points within the focal organization.Shulman emphasizes the importance of both direct and indirect links as they are used as a means of accessing resource nodes.For example,Steier and Greenwood (1995)show how venture capitalists act as brokers,linking entrepreneurial ventures with such players as retail outlets,marketing consultants and other ?nancial sponsors.In this line of research,the main unit of analysis is the number of links between an organization and its context.Irrespective of whether the links are direct or indirect,what matters is the number of links (Larson,1992).

Another strand of research emphasizes the number of links to different clusters of information and resources accessed by those resources,rather than the number of ties per se (Burt,1992).‘Size is a mixed blessing”.More contacts can mean more exposure to valuable information,more likely early exposure,and more referrals.But increasing network size without considering diversity can cripple the network (Burt,1992).Burt stresses the role of diversity as a key attribute of size,implying that several single ties to multiple sources -ties to clusters of people not in communication with other clusters -than multiple ties to the same source,are more important.

The number of relationships an actor in a network manages is captured by degree centrality measure.For research purposes,a network is represented by a square “adjacency”matrix,the cells of which re?ect the ties among the actors in the network.For example,two VCs coinvesting in the same portfolio company can be considered as having a tie.With the number of ties increasing,the VCs would have more opportunities for exchange and so become in?uential,or central,in a network.We examine this by looking at whether at least one syndication relationship exists between VCs i and j .Adjacency matrices can be “directed”or “undirected”.In the case of directed matrices,we can differentiate between the originator and the receiver of a tie.Thus,we can have information about syndicates led by VC i versus those led by VC j .It allows one to distinguish between VCs who receive many ties and those who originate many ties.In the ?rst case,VCs are invited to be syndicate members by many lead VCs,whilst,in the other case,lead VCs syndicate with many other VC members.This produces two directed measures of degree centrality.VC i ’s indegree counts if at least one syndication relationship exists in which VC j is the lead investor and VC i is a syndicate member.When one counts the number of other VCs a VC ?rm has invited into its own syndicates (i.e.reciprocity),one has an outdegree measure.

Network strength

Granovetter (1973,1985)argues that network “strength”where ties with close friends and associates who are likely to know one another,is critical for understanding the network relations.Whilst recognizing the value in weak ties as they represent diverse conduits of information,this framework focuses on “strong”ties as,for example,relations within personal networks,that allow trust and/or moral obligation to play its role as an underlying support mechanism,thus reducing the risk of opportunism and

cheating(Johanson and Mattson,1987;Powell,1990).Therefore,in addition to counting the number of actor relationships(i.e.degree),it would also be useful to measure their “strength”or“quality”or closeness in our setting.“Eigenvector centrality”is generally used to measure“closeness”(Bonacich,1987),which is an actor’s total ties to other actors weighted by their respective centralities.Thus,we can measure the extent to which a VC is connected to other well-connected VCs.

Network content

In addition to structure,understanding network content is also important in the way it affects individual actors and organizations.In this respect,Tichy(1981)develops a typology of four types of resources accessed through networks:information,goods and services,expressions of affect or emotional support,and political in?uence. Information resources can be envisaged in terms of management expertise,and professional advice provided by accountants,lawyers and consultants.In the present context,goods and services are?nancial resources,as well as assets such as plants and equipment.Steier and Greenwood(1995)discuss effective support in relation to its signi?cance for start-up companies.They also provide an example of how networks can be used for political purposes or for the mobilisation of in?uence.Thus,it will be useful to know those actors on whom many others must rely to make connections within the network.When a VC acts as an intermediary by bringing together VCs with complementary skills that lack a direct relationship between them,this can be captured by“betweenness”measure.It is measured by the proportion of all paths linking actors j and m that pass through actor i.

Indirectly,these network measures also capture the involvement of VC?rms in portfolio companies.Elango et al.(1995)identify three levels of involvement:inactive, active advice-giver,and hands-on.Involvement by the inactive group is mainly con?ned to attendance at board meeting.One example of“hands-on”involvement approach is the?rms’emphasis on networking among its portfolio companies.The concept refers to networks of companies bound together by mutual obligations and contacts.Entrepreneurs gain access to VC’s portfolio of companies and associations with market leaders.These relationships are the foundations for strategic alliances, partnership opportunities and the sharing of insights to help build new ventures faster, broader and with less risk(Norton and Tenenbaum,1993).Networking also allows the development of a network of companies that helps create synergies and pooled resources for growth and development(Franke et al.,2006).The professional respect and regard in which VC is generally held and the in?uence that it enjoys with other investors are major sources of networking success.

Empirical speci?cations

VCs often engage in joint projects that allow them to participate in more projects, especially when they are constrained by available resources.There is empirical evidence that suggests that syndicated projects offer higher returns than projects ?nanced by a single VC(stand-alone projects)(Brander et al.,2002).The way syndicated VCs offer improved managerial support in the form of higher reputation, and a larger variety of contacts for their portfolio?rms than a single VC,accounts for the higher return.The syndication investment strategy is primarily aimed at high-risk environments,where it reduces the asymmetries of information and select the projects

of the highest quality (Wilson,1968).By combining equities in an investment,either in the same investment round or,more broadly de?ned,at different points in time,syndicated projects mitigate investment risks.

Syndication may also be advantageous when inexperienced VCs join in.Experienced VCs are likely to contribute to the project’s success with their knowledge and expertise,and thus increase the expected project value.In the process,they are also likely to help inexperienced VCs to gain valuable know-how for future deals when they invest in a project together with skilled partners.To fully investigate the effects of syndication investment,we examine directed and undirected centrality measures as discussed above (see also Hochberg et al.,2006).Entry to and exit from the network may change each VC’s centrality,thus changing the structure of the network and the relationships it supports.To keep track of these changes,we construct our adjacency matrices over trailing three-year windows.

Descriptive statistics are presented in Table I.The parent of the average sample fund has normalized outdegree of 8.13percent,indegree of 7.12percent,and degree of 12.14percent.This suggests a number of interesting features of syndication investment,in the UK and Continental Europe:the average VC,when acting as lead,involves a little over 8percent of all VCs active in the market at the time,as coinvestors;has been invited to become a syndicate member by around 7percent of all VCs;and has coinvestment relationships with a little over 12percent of the other VCs (ignoring its and their roles in the syndicate).These relatively low degree centrality scores suggest that VC relationships are relatively exclusive and stable as they often

Benchmark analysis

Earlier studies on venture capital and VC fund performance have often found the signi?cant impact of log fund size and a set of vintage year dummies on performance (Kaplan and Schoar,2005;Hochberg et al.,2006).Table II presents a similar type analysis.

In the ?rst column,we report results for when only size is included.In this case,we do not ?nd any signi?cant relationship.We then use a dummy that equals one for ?rst-time funds in column 2.Assuming that seed,or early-stage funds invest in riskier companies and thus have relatively fewer successful exits,we also include in this column a control for such investment vehicles.Similarly,we control for corporate VCs.As expected,?rst-time funds perform signi?cantly poorly.The results for the seed and early stage funds are similar,but the coef?cients on corporate VCs are positive.Our subsequent analysis (column 3)includes a proxy for the investment opportunities available to funds when deploying their committed capital (using B/M ratio).In this case,we observe the impact of a more favourable investment climate at the time a fund invested its capital as signi?cantly higher exit rates are recorded thereafter.

The right of venture ?rms to nominate directors of portfolio companies is an important component of their control rights.The role of VC ?rm nominees may,however,extend beyond control.Goodstein et al.(1994)identify three functional duties of company boards:

(1)Networking activities,which are to do with forming links between the company

and its external environment,and securing critical resources.

(2)Monitoring activities which include dealing with internal governance issues,

monitoring company performance and providing mechanisms to align the interests of management with shareholders.

(3)Strategy-making activities contributing to the company’s strategic

decision-making processes.

Wijbenga et al.(2003)follow this framework in reviewing the role of private equity investors in the boards of portfolio companies.

First,in relation to networking activities,they suggest that there is evidence that the boards of portfolio companies(on which general partners usually sit)provide an interface with other investor group members,provide industry contacts and contacts with professionals.Private equity?rms also assist in obtaining alternative equity capital.Second,in relation to monitoring activities,there is evidence that the boards of portfolio companies monitor?nancial performance,monitor operational performance, and evaluate the portfolio company’s strategy and product market opportunities in order to develop the new venture’s strategy to changing circumstances.Finally,in relation to strategy-making activities,there is evidence that the boards of portfolio companies serve as a sounding board,assist in formulating business strategy,assist in dealing with short-term crises or problems,and recruit and/or replace managers.

To investigate these matters,in column4our variables of interest are the venture and investment experience of the fund’s parent?rm and?rm’s partners.We?nd a signi?cantly improved performance for funds with more experienced parents and individual partners.We?nd similar results for portfolio company board membership, thus emphasizing the literature’s conclusions,as discussed above.

VC networks and performance

In the previous section,we investigated a benchmark VC?rm performance model, while controlling for fund characteristics,competition for deal?ow,investment opportunities,corporate board and venture and parent?rm experience.Now,we investigate the extent to which VC’s networking improve the performance of its fund. The results are largely consistent with the predictions of our framework.In Table III, we add our?ve network measures to the speci?cations shown in Table II,thus presenting estimates for four separate regression models.We?nd that networked VC ?rms are associated with signi?cantly better fund performance in each of the speci?cation.

The results show that there are three signi?cant network effects;indegree stands out as the most important factor in relation to its effect on network relations.This is closely followed by two other measures–eigenvector and degree.Overall,these results suggest that large bene?ts accrue to VC?rms when they have many ties (degree).These ties have more store when VCs are invited into many syndicates (indegree),and when they involve other well-connected VCs(eigenvector).Another measure,outdegree,has a similarly relatively large effect,which implies that a VC ?rm’s investment in future reciprocity pays off handsomely(see also Lerner,1994). When we examine the signi?cance of a VC?rm’s ability to act as an agent between other VCs(betweenness)we do not?nd a signi?cant relationship.This reveals the fact

that indirect relationships (those requiring intermediation)are much less important in the way venture capital industry is organized.

From these results,one can also argue that networked ?rms are best placed to adopt a hands-on approach to managing their portfolio companies.As discussed,VC ?rms taking a hands-on approach both monitor portfolio ?rms through,for example,reviewing management accounts and board minutes,and through involvement in decisions such as the purchase of major capital items,acquisitions and disposals,changes in strategic direction,appointment of directors and auditors,and changes in capital structure.The alternative hands-off,or passive approach,mainly involves monitoring portfolio ?rms,for example through management accounts.VC ?rms taking a hands-off approach are,

however,likely to become actively involved with the portfolio company under certain circumstances such as failure to meet agreed targets or default of payments.

In our analysis,we?nd that the better-networked VCs generate rents by developing superior relational approaches.For example,when a VC in a network reports to the other members about the accomplishment of pre-set performance targets,both partners generate rents through exchange of knowledge valuable to one another. Frequent interactions between the parties may enhance access to each other’s knowledge base and increase the capability of processing complex knowledge. However,this analysis does not take into account the possibility that this networking approach is valued only when it affects performance.To account for the endogenous relation between VC networks and performance,we also estimate the performance effects of VC network characteristics with two stage least squares(2SLS).Table IV

provides 2SLS results,which show that VC networks indeed raise ?rm performance.In fact,the results are stronger than the OLS regressions,especially the association between degree and VC performance.

Conclusion

Networks perform several important roles in venture capital (Dubini and Aldrich,1991):allowing access to resources without incurring the costs of vertical integration;acting as conduits for information;and providing legitimacy to new market entrants (Burt,1992;Larson,1992).Given the important role of syndicates in the ?nancing of new ventures,understanding the process by which syndicate networks are developed and managed remains a signi?cant aspect of the entrepreneurial process.In this study,we examine the performance consequences of a particular form of organizational choice:when market transactions are characterized by strong relationships and https://www.360docs.net/doc/5d1446862.html,ing VCs syndicate portfolio company investments in a comprehensive sample of UK and Continental Europe based VCs over the period 1995-2005,we examine the relation between fund performance and various measures of networking among VCs.We control for various determinants of VC investment performance,and ?nd that networked VCs realize signi?cantly better performance.These results suggest that VC ?rms need to pay close attention to their relational strategies,as networking is likely to add value to ?rm operations.

调查方法与条件

第二节调查方法与条件 一、调查方法 市场调查有许多方法,企业市场调查人员可根据具体情况选择不同的方法。市场调查方法可分为两大类,第一类按选择调查对象来划分,有全面普查、重点调查、随机抽样、非随机抽样等;第二类是按调查对象所采用的具体方法来划分,有访问法、观察法、实验法。下面简要分析每一种调查方法特征。 1、调查对象划分 A、全面普查全面普查是指对调查对象总体所包含的全部个体都进行调查。可以说对市场进行全面普查,可能获得非常全面的数据,能正确反映客观实际,效果明显。如果把一个城市的人口、年龄、家庭结构、职业、收入分布情况系统调查了解后,对房地产开发将是十分有利的。由于全面普查工作量大很大,要耗费大量人力、物力、财力,调查周期较长,一般只在较小范围内采用。当然,有些资料可以借用国家权威机关普查结果,例如可以借用全国人口普查所得到的有关数据资料等。 B、重点调查重点调查是以总体中有代表性的单位或消费者作为调查对象,进而推断出一般结论。采用这种调查方式,由于被调查的对象数目不多,企业可以较少的人力、物力、财力,在很短时期内完成。如调查高档住宅需求情况,可选择一些购买大户作为调查对象,往往这些大户对住宅需求量,对住宅功能要求占整个高档商品住宅需求量的绝大多数,从而推断出整个市场对高档住宅的需求量。当然由于所选对象并非全部,调查结果难免有一定误差,市场调查人员应引起高度重视,特别是当外部环境产生较大变化时,所选择重点对象可能不具有代表性了。例如,1993年国家加强了宏观调控,一些房地产公司贷款受到限制,资金不足,开工不正常,水泥等材料需求量急剧减少。在这种情况下,公司应及时调整,重新选取调查对象,并对调查结果认真分析,只有这样的市场调查结果才能为企业制定策略提供有用的根据。 C、随机抽样。随机抽样调查是在总体中随机任意抽取个体作为样本进行调查,根据样本推断出一定概率下总体的情况。随机抽样在市场调查中占有重要地位,在实际工作中应用很广泛。随机抽样最主要特征是从母体中任意抽取样本,每一样本有相等的机会,即事件发生的概率是相等的,这样可以根据调查的样本的机会,即事件发生的概率是相等的,这样可以根据调查的样本空间的结果来推断母体的情况。它又可以分为三种:一是简单随机抽样,即整体中所有个体都有相等的机会被选作样本;二是分层随机抽样,即对总体中所有个体都有相等的机会被选作样本;二是分层随机抽样,即对总体按某种特征(如年龄、性别、职业等)分组织(分层),然后从各组中随机抽取一定数量的样本;三是分群随机抽样,即将总体按一定特征分成若干群体,随机抽样是将部分作为样本。分群抽样与分层抽样是有区别的:分群抽样是将样本总体划分为若干不同群体,这些群体间的性质相同,然后将每个群体进行随机抽样,这样每个群体内部存在性质不同的样本;而分层抽样是将样本总体划分为几大类,

湘艺版五年级音乐《长白山下的歌谣》 教学设计 《长白山下的歌谣》教学设计 教材版本:湘艺版音乐教材 教学对象:五年级上期 一、教学案例: (一)题:《长白山下的歌谣》音乐综合 (二)教材版本:湘版新标实验教材 (三)年级:五年级 (四)教具准备:钢琴、AI、打击乐器、朝鲜族服饰、长鼓、金达莱花。 (五)教学目标: ①、认知目标:认真听赏朝鲜民歌《道拉基》,学习三拍子节奏特点。 ②、能力目标:通过小组合作学习(设计身势节奏、用长鼓为歌曲伴奏、即兴歌舞等形式)培养学生的创新能力、合作能力,体验朝鲜族民歌的韵律。 ③、情感目标:通过感受性学习歌曲《金达莱花开朵朵红》,了解朝鲜族人民勤劳淳朴、团结互助、热情好客、能歌善舞的优良传统与民族风情。 (六)设计思路: 五十六个民族五十六枝花,生活在吉林省长白山脚下的

朝鲜族,其歌舞有着独特的节奏韵律。湘版新标实验教材五年级上册第八单元题为:《长白山下的歌谣》,它引起了我的研究兴趣。本单元的教育主题为:用民族音乐激发学生的爱国情感,实现多元文化的交流。即:通过音乐去感受民族文化,进而去了解民族文化;反之,通过文化,我们才可以去体验民族音乐,整体地去认识民族音乐。本时选用听赏《桔梗谣》和演唱歌曲《金达莱花开朵朵红》这两部分内容,教学设计的基本思路是:使学生通过多种形式听、唱“长白山下的歌谣”,深刻体验民族音乐“原生态”的美,以及其歌舞文化、思想内涵;在师生平等互动的学习氛围里,通过实践创作、对歌曲的再表现等形式,激发学生热爱民族音乐、热爱我们伟大祖国的情感。 堂教学中我以“新程”为指导思想,对教学设计进行了一些新的尝试。以下结合自己教学实践中的堂教学个案,和大家共同评析与探讨。 (七)教学过程 ᠄ 导入新过程:即“看风景”。 、AI播放《大长今》影片,背景音乐:《大长今》的主题曲《希望》。 (学生起立,跟随老师自由律动。) 师:刚才同学们听到的旋律出自?

调查基本方式、方法和步骤

调查基本方式、方法和步骤 贷款调查是防范贷款风险最重要的环节之一,搞好贷款尤其是大额贷款调查,是审贷分离制度的基本要求,确保贷款“三性”原则实现的前提和基础。 大额贷款调查是指对借款人进行贷前调查核实。大额贷款调查主要有:查验客户证照等资料→调查核实客户借款用途、客户信用及品行状况→调查核实客户第一还款来源→调查核实第二还款来源→调查核实客户关联交易和关联人情况→调查核实客户与农村信用社往来情况→出具调查报告。 调查基本方式、方法和步骤 一、拟定调查提纲,搜集与借款申请人----企业相关的行业资料等。 二、通过外围,侧面了解相关信息 (一)侧面了解企业关键人员。 (二)侧面了解企业的产品情况。 三、现场调查核实。 (一)询问相关人员,了解企业状况 1、询问主要负责人。 2、询问财务负责人。 3、询问车间等基层工作人员。 (二)实地查看 1、实地查看了解企业的生产规模和经营状况。 2、实地查看、盘点企业的原材料、产成品等情况。 (三)对企业财务帐表等进行全面调查核实

四、通过逻辑性分析,得出初步结论 调查核实的主要内容 ※一、调查核实客户提供的证照、批文等是否真实、齐全、有效。主要调查核实以下证照。 (一)基本证照: 1、营业执照是否年检合格; 2、组织机构代码证是否年检合格; 3、税务登记证(国税、地税)是否年检合格; 4、法定代表人的身份证明是否真实有效; 5、贷款卡是否年检合格; 6、公司章程或依法成立公司的合伙协议是否合法有效; 7、注册资本是否经有权部门验资,且出具了验资报告; 8、开户许可证是否真实有效; 9、属于个体工商户的,个体工商户营业执照是否年检合格。 (二)不同行业的客户应核实其他证照(批文): (三)属于固定资产贷款除上述证照(批文)外,还应重点核实以下文件: ※二、调查核实借款用途。 ※三、通过非财务因素调查分析、核实客户信用及品行状况(一)调查借款人的组织形式及变化情况 (二)调查客户公司治理结构情况 (三)调查客户管理层的素质和稳定性

店址调查及其评估方法

店址调查及其评估方法 (1)商圈的调查 商圈,也称商业圈,是指店铺吸引消费者的地理区域。商圈的大小,与消费者所购买商品的特性、消费习惯、交通因素等有很大关系。一般以店铺设定的地点为圆心,周围一定距离为半径所划定的范围作为商圈设定考虑的因素,但实际上,还应综合店铺的业态形式、商品的特性、交通网的设立等一系列因素。而且商圈的形式不一定都是同心圆,店铺类型、规模、周围有无竞争者,顾客往返时间和交通障碍等都会影响商圈调查的结果。 商圈包含三个层次:中心商业田、次级商业田和边缘商业圈。中心商业圈占这一店铺顾客总数的55%一70%。这是最靠近店铺的区域,顾客在人口中所占的密度最高,每个顾客的平均购货额也最大,很少同其他商圈发生重叠。次级商业圈包含这一店铺顾客总数的15%一25%。这是位于中心商业圈外围的商圈,顾客较为分散,一般日常用品对这一商圈的顾客缺少吸引力。边缘商业圈包含了剩余部分的顾客,他们最分散,如便利店对他们就不具有吸引力,只有一些特殊晶、选购品才会吸引他们的到来(见图1-1)。 ①有效商圈范围的调查 对于新设店铺商圈的划定,往往通过调查评价,包括对市场趋势的分析和对消费者的调查。 市场趋势分析要收集有关资料,如人口分布的预测、新住宅的兴建、公共交通运输、城市规划等方面的资料。对消费者的调查,如往返于商店的距离和花费的时间多少是顾客乐于接受的,一家商店的坐落插所要具备哪些特征才能吸引顾客,最可能来新店的人们的住址等。分析市场趋势和调查消费者这两方面可以同时采用,也可只用其中一项,同样都可为勾划商圈轮廓提供依据。 要划定一家新设店铺的商圈界限,可使用美国学者威廉·雷利 提出的雷利法则,也可称为“零售引力法则(定律)”。他认为,商圈规模由于人口的多少和距离店铺的远近而有所不同,店铺吸引力是由最临近商圈的人口和里程距离两方面发挥作用。

调查方案设计

调查方案设计Newly compiled on November 23, 2020

二、调查方案设计 (一)调查目的 为了探究《王者荣耀》在激烈的手游市场中脱颖而出并用一年多的时间就占领了手游市场半壁江山的原因,了解其在大学生群体中的受众情况,在此基础上寻找移动手游的发展方向,为同类游戏的发展提供借鉴。本次调查目的具体如下: 1.了解《王者荣耀》在大学生群体中的受众情况; 2.了解《王者荣耀》的大学生玩家的基本特征; 3.了解大学生玩家对《王者荣耀》的表面印象以及玩《王者荣耀》的主要目的; 4.了解《王者荣耀》的大学生玩家接触《王者荣耀》的途径以及时间段,以得知《王者荣耀》的宣传营销方式对大学生是否有效; 5.通过对《王者荣耀》的大学生玩家的游戏习惯的调查,了解大学生玩家的游戏消费观念、游戏玩伴特点以及游戏时间分配等情况; 6.了解《王者荣耀》对大学生玩家社交情况的影响; 7.了解《王者荣耀》的大学生玩家的主观感受,包括对于游戏界面、角色设计等其他游戏特性的看重程度和满意度以及对《王者荣耀》的总体满意程度; 8.结合以上调查结果,针对提高《王者荣耀》在大学生中的留存率提供建议。(二)调查思路 本次调查从在校大学生是否接触以及如何接触王者荣耀开始,了解王者荣耀在大学生中的流行程度和兴趣浅淡,探寻玩家活跃度随着历史版本变动而变化的规律。接着是对于大学生游戏习惯的调查,如游戏时长、游戏伙伴、游戏水平等因素造成的影响,之后是

关于游戏目的和消费情况的调查。以上是对于一些客观因素的调查,紧随其后的是主观因素——即大学生群体对于王者荣耀乃至手游的满意度评价问题,为了运营商改善游戏的客户体验和提高游戏在大学生群体中的留存率具有指导意义。调查的同时也会收集被调查者的基础信息,用于描述性统计以及部分问题的交叉分析。 (三)调查对象 虽然《王者荣耀》有庞大的玩家基数,但是大学生作为年轻人中的特殊消费群体,人生观、价值观渐趋成熟,有着接受新鲜事物能力强、视野开阔等特点,对《王者荣耀》的火爆有着不容小觑的作用。因此,以大学生群体作为调查对象,对大学生玩家对《王者荣耀》的行为及态度进行调查分析,有助于把握《王者荣耀》在大学生消费群体中的品牌效应、宣传力度等方面的现状,对《王者荣耀》在大学生群体中留存率的提高以及为《王者荣耀》乃至其他同类手游的未来发展提供建议有着重要的意义。 (四)调查期限与时间安排 调查的准备工作于2017年10月下旬开始,11月上旬开始实施,12月中旬完成调查。调查的过程中针对部分出现的问题,整理集结后于11月下旬进行了一次问卷的修改。调查结束后进行数据的整理和分析,于12月下旬完成调查报告。 (五)调查内容 1.受访者的基本信息情况 2.受访者的接触到游戏的方式及时间 3.受访者玩游戏的主要目的 4.受访者作为玩家的实力

调查研究常用九大方法

调查研究常用九大方法 发布时间:2015年04月08日作者:孙亚男 选择合适的调研方法直接关系到调研工作开展。笔者结合调研工作实际,将常用的九大调研方法进行介绍分析,供大家调研时参考。 1.实地观察法。调查者在实地通过观察获得直接的、生动的感性认识和真实可靠的第一手资料。但因该法所观察到的往往是事物的表面现象或外部联系,带有一定的偶然性,且受调查者主观因素影响较大,因此,不能进行大样本观察,需结合其他调查方法共同使用。通常适用于对那些不能够、不需要或不愿意进行语言交流的情况进行调查。 2.访谈调查法。该法是比实地观察法更深一层次的调查方法,它能获得更多、更有价值的信息,适用于调查的问题比较深入,调查的对象差别较大,调查的样本较小,或者调查的场所不易接近等情况。包括个别访谈法、集体访谈法、电话访谈法等。但由于访谈标准不一,其结果难以进行定量研究,且访谈过程耗时长、成本较高、隐秘性差、受周围环境影响大,故难以大规模进行。 3.会议调查法。这种方法是访谈调查法的扩展和延伸,因其简便易行故在调查研究工作中比较常用。通过邀请若干调查对象以座谈会形式来搜集资料、分析和研究社会问题。最突出的优点是工作效率高,可以较快地了解到比较详细、可靠的社会信息,节省人力和时间。但由于这种做法不能完全排除被调查者之间的社会心理因素影响,调查结论往往难以全面反映真实的客观情况。且受时间条件的限制,很难做深入细致地交谈,调查的结论和质量在很大程度上受调查者自身因素影响等。 4.问卷调查法。即间接的书面访问,该法最大优点是能突破时空的限制,在广阔的范围内,对众多的调查对象同时进行调查,适用于对现时问题、较大样本、较短时期、相对简单的调查,被调查对象应有一定文字理解能力和表达能力。如对某地区农村党员教育培训情况调查、中小学教师队伍科研现状的调查等。由于问卷调查法只能获得书面的社会信息,而不能了解到生动、具体的社会情况,因此该法不能代替实地考察,特别是对那些新事物、新情况,新问题的研究,因配合其他调查方法共同完成。 5.专家调查法。这是一种预测方法,即以专家作为索取信息的对象,依靠其知识和经验,通过调查研究,对问题作出判断和评估。最大优点是简便直观,特别适用于缺少信息资料和历史数据,而又较多地受到社会的、政治的、人为的因素影响的信息分析与预测课题。广泛应用于对某一方案做出评价,或对若干个备选方案评价出相对名次,选出最优者;对达到某一目标的条件、途径、手段及它们的相对重要程度做出估计等。 6.抽样调查法。指按照一定方式,从调查总体中抽取部分样本进行调查,并用所得结果说明总体情况。它最大的优点是节约人力、物力和财力,能在较短的时间内取得相对准确的调查结果,具有较强的时效性。组织全面调查范围广、耗时长、难度大,常采用抽样调查的方法进行检查和验证。比如开展全省党风廉政建设社会民意调查、流动党员现状社会调查等。局限性在于抽样数目不足时会影响调查结果的准确性。 7.典型调查法。指在特定范围内选出具有代表性的特定对象进行调查研究,借以认识同类事物的发展变化规律及本质的一种方法。在调查样本太大时,可以采用此种方法。但必须注意对象的选择,要准确地选择对总体情况比较了解、有代表性的对象。如某地级市开展对区县市农村党员致富情况的调查,应选取经济发展较快、农村党员致富能力较强的县市作为典型调查对象。

效果评估调查报告

效果评估调查报告 为了解目前我辖区居民健康知识知晓率和健康行为形成率的现状,促进辖区居民健康知识知晓率的提高和健康行为的形成,检验我院日常健康教育工作的成果,按照《旗健教所关于做好2013年基本公共卫生服务健康教育效果评估的通知》的要求,对辖区居民健康知识知晓率和健康行为形成率进行了抽样调查,现将此次抽样调查工作评估总结如下: 一、调查目的 通过全面系统的调查,了解辖区居民健康知识知晓率和健康行为形成率的现状,为下一阶段制定健康教育工作计划和开展健康行为干预提供依据。 二、调查对象 **村、**村、**社区、**5个村(居委会)各20人,共100名18-60岁常住居民。 三、调查方法 本次调查采取调查问卷的方式进行,调查问卷由阿荣旗健康教育所统一设计和提供。调查问卷分基本健康知识和理念、健康行为和技能两部分,内容主要包括健康生活方式、疾病防治、意外伤害与急救、控制行为危险因素等内容。 本次调查由健康教育专业人员协同乡村医生到社区居民院落开展随机调查,现场填写问卷,核对后回收,并根据

结果进行评估。 四、质量监控 调查前对调查员人员进行培训,严格控制调查问卷质量,严禁弄虚作假。每个调查小组由2-3人组成,对有缺项、漏项或模糊不清者重新进行问卷。 五、调查结果 本年度调查共测试100人,健康知识部分共10题,健康行为部分共10题,测试结果为:居民健康知晓率 %,居民健康行为形成率 %,调查人群分布情况下: (一)年龄分布情况: (二)文化程度分布情况: (三)居民健康知识知晓情况: 各分数段人数统计表

总知晓率统计表 注:应答题=答卷人数×每卷题数 知晓率=答对题数/(提问题数×抽样人数)×100% (四)居民健康行为情况: 总行为行成率统计表 六、分析与建议 1、从今年调查的结果来看,无论是健康知识知晓率,还是健康行为形成率均比上年有大幅度提高,说明我院的健康教育工作取得了一定的效果。今后,我们还要更加努力,针对存在的问题,提出整改意见,制定整改措施,不断提高我院健教人员的健康教育工作理论水平和工作技能。 2、在健康知识方面,本次测试涉及到多方面的内容。测试中我们发现大部分居民对食盐日摄入量,高血压的诊断标准,确认糖尿病的常见症状,艾滋病由性传播,戒烟、限酒、适量运动有利于健康等基本都能回答正确。对高血压和
