经济周期、融资约束与流动性管理--基于交通运输业的实证分析

经济周期波动对交通运输企业的流动性管理有显著影响。经济周期通过产品市场渠道、资本市场渠道影响企业的外部融资成本,从而导致企业在经济衰退期面临更加严峻的融资约束,并传导到流动性管理行为。与其他行业相比,我国交通运输企业的流动性管理整体上受经济周期的冲击更为显著。因此,交通运输企业必须实施有效的周期性流动管理,政府部门也应该实施周期性的差异化产业政策。     

Uncertainty and Growth of the Firm

Using data from a survey of 1,097 small and medium-sized non-listed Dutch firms we investigate the relation between growth of the firm and uncertainty. We focus on the impact of sales uncertainty on various types of investment. We find that sales uncertainty, measured by the conditional variance, has a mixed impact on various investment decisions. We include an analysis of the relevance of financial structure and firm size on the growth-uncertainty relation.     

企业成长阶段及其划分标准:一个评论性回顾

企业成长阶段理论已有近半个世纪的发展历程,但关于成长阶段划分标准及阶段数目直到今天都还处于无休无止的争论之中。探讨相关文献中有关成长阶段理论的起源、各种划分标准及相应阶段数目做了一个评论性回顾,指出了各种标准的优点和缺点,以及今后应该解决的问题。     

Factor Substitution, Average Firm Size and Economic Growth

This paper extends the Lucas (1978, The Bell Journal of Economics 9(2), 508–523) analysis of firm size by taking into account a normalised aggregate CES production function. In a general equilibrium framework it is proved that there is an inverse relation between the elasticity of substitution and average firm size. If interpreted together with the fact that richer countries are characterised by a higher elasticity of substitution, this result can explain why the recent literature finds a positive association between the importance of SMEs in an economy and its stage of development, but seems to fail in finding causality between the two. Both have a common origin: a high value of the elasticity of substitution. This paper also provides a first empirical test of the theory proposed using cross-country data from both developed and developing countries.     

货币流动性和市场流动性:波动与风险

目前,货币流动性和市场流动性的关系成为股票市场参与者关注的焦点。本文分析了货币流动性与市场流动性的联系,实证研究了货币流动性和市场流动性的波动关系,以及货币流动性对市场流动性风险的影响,发现货币流动性M2、M1和市场非流动性动态负相关,M0与市场非流动性动态不相关;货币流动性M2和M1的正向冲击能一定程度降低市场流动性波动风险,而M0会增加市场流动性波动风险,市场流动性风险自身是影响市场后期流动性风险的最大因素。     

现金持有、融资约束与企业价值——基于门槛回归模型的实证检验

文章基于门槛回归模型,对融资约束是否会影响现金及超额现金与企业价值的关系进行实证检验。结果表明,现金及超额现金与企业价值的关系均存在显著的门槛效应。在弱融资约束企业,现金及超额现金的账面价值高于其市场价值,而在强融资约束企业,现金及超额现金的账面价值低于其市场价值,这支持了代理理论和融资约束理论,说明弱融资约束企业滥用现金的代理问题较为严重,现金持有对企业价值具有负向影响,强融资约束企业持有现金,能够抓住更多投资机会,现金持有对企业价值具有正向影响。     

关于金融市场化减少消费流动性约束的实证分析

本文根据扩展的生命周期-永久收入假说以及Euler方程建立模型,对中国大陆31个省市自治区1979-2004年的整体情况和东、中、西部的区域情况进行GLS面板数据分析,结果表明,金融市场化通过各种渠道降低了消费者面临的流动性约束,释放了消费需求。从国际比较上看,金融市场化还能进一步释放消费需求。从地区比较上看,金融市场化减少消费流动性约束的作用在经济相对发达的东部和中部地区更为显著。     

对外贸易影响我国资本形成的效应与地区差异——基于系统广义矩估计的动态面板数据分析

文章依据我国30个省、自治区和直辖市(西藏除外)1985～2006年的数据,采用动态面板数据模型以及Blundell和Bond(1998)提出的系统广叉矩估计法,把对外贸易对我国总体以及东、中、西部地区资本形成的效应进行了实证分析.其结果显示当期和滞后1期的进出口贸易对我国总体及东、中、西部地区的当期资本形成有正或负效应,且这种正负效应在东、中、西部地区之间存在明显的地区差异.还分析了产生这一结果的原因并提出措施发挥对外贸易对我国资本形成的正效应,尽量缩小正效应在不同地区的差异.     

流动性约束对农户创业选择行为的影响——基于晋、甘、浙三省894户农民家庭的调查

流动性约束对中国农户创业行为有着切实的阻碍作用。通过分别利用"家庭土地出租收入"和"礼金收入"作为工具变量来克服流动性约束变量的内生性问题,基于晋、甘、浙三省农户的研究表明:流动性约束对中国农民是否选择创业以及选择何种创业类型具有显著的、一致的阻碍作用;此外,只有源于正规金融部门的流动性约束才对农户是否选择创业和创业类型产生抑制性作用,而非正规金融部门的流动性约束则不会对农户创业行为产生抑制作用。因此,旨在增加农民收入的创业扶持政策应该更加注重畅通农户通过正规金融渠道缓解流动性约束,而不应过分强调非正规金融渠道的作用。     

企业规模问题的三维综合分析

在对交易费用理论、规模经济理论及范围经济理论等有关理论进行回顾和总结的基础上,从生产链、产量以及产品种类等三个维度对企业的纵向规模、横向规模、多元化规模及其各自的影响因素进行了比较深入的分析和探讨,可以系统地理解整体规模的含意及其不同维度规模之间的关系;可以更好地解释现实中不同企业在规模结构和经济效率的差异,使企业规模的研究,不能一直停留在对有关概念的无谓争论阶段。     

区域对外开放度与通货膨胀动态不一致性——基于动态面板GMM的实证研究

通过研究开放经济条件下通货膨胀的影响因素及其与对外开放度之间的动态不一致性,应用中国大陆29个省市及东部、中部、西部各地区所属省份的省际面板数据对通货膨胀率与对外开放度之间的非线性关系进行实证分析.结果表明,对外开放度特别是对外贸易量的增长能够有效地控制一国或者地区的通货膨胀率,且中国东部、中部和西部不同地区间显示出一定的差异性,对比发现对外开放政策对东部和中部地区宏观经济稳定性的调控效果最为显著.     

农村金融流动性风险分析及预防

随着近年来金融危机的出现和潜在危机的浮出,流动性风险成为了值得各国、各金融机构关注的风险隐患。通过对部分涉农金融机构的负债情况和机构分布情况进行数据归纳,体现出我国现行农村金融机构信贷质量差,资金的时效性强等多方面的问题。预防农村金融流动性风险,应建立特有的农村金融机构人才培养机制,认真考察不同地区的流动性资金的走向情况,做出合理的流动性风险管理规划,并加强各地区的联系和沟通,组建风险预警体系和完善相应的保险机制。     

高新技术企业融资约束与R&D投资和企业成长性的相关性研究

本文在构建高新技术企业融资约束指数的基础上,理论分析并实证检验了高新技术上市公司融资约束与R&D投资和成长性的相关性。结果表明:融资约束程度越高的企业,R&D投资越低;融资约束程度高的高新技术企业R&D投资显著依赖内源融资,而融资约束程度低的高新技术企业R&D投资对内源融资并不具备依赖性;融资约束程度高的高新技术企业R&D投资对企业成长性的推动作用明显低于融资约束程度低的高新技术企业。     

Interdependencies in the Dynamics of Firm Entry and Exit

This paper investigates the interdependence between firm entry and exit from an industrial dynamics perspective. The paper discusses how entry and exit rates in industrial sectors are affected by previous exit and entry rates. Economic theory presents two different approaches to how entry and exit of firms are interrelated, the multiplier effect and the competition effect. This paper intends to investigate which force is the predominant one, for entry and exit patterns, respectively. The empirical analysis is based on data for 25 Swedish manufacturing industries at the 2-digit SIC level, during the period 1991–2000. In the estimation work the study applies a dynamic panel data approach as suggested by Anderson and Hsiao [Journal of the American Statistical Association, 76:598–606, 1981] and Arellano and Bond [Review of Economic Studies, 58(2):277–297, 1991]. With respect to entry, the empirical results support the multiplier effect such that entry stimulates future entry, but also a competition effect such that past exit induces additional entry. With regard to exit, on the other hand, the competition effect rules, implying that previous entry causes subsequent exit and previous exit reduces subsequent exit.      

股票流动性、公司治理与企业经营绩效——基于退出威胁与锁定效应的理论与实证研究

文章采用博弈论的分析框架探讨了股票流动性的两大效应,即"退出威胁"与"锁定效应".研究表明,当股票流动性较低时,机构投资者的退出策略不可行,被迫参与上市公司的监督行为,即表现为"锁定效应",且股票流动性越低,这一效应越明显.然而,随着股票流动性的进一步增强,机构投资者的退出策略开始变得可信,从而可以通过一定的触发策略迫使管理者选择尽职,因而表现为"退出威胁",且股票流动性越高,这一效应越明显.因此,总的说来,股票流动性与经营绩效之间会呈现一个先减后增的U型关系.文章采用高频交易数据构造相对有效价差与相对报价价差衡量股票流动性对上述假说进行了检验,其实证结论支持了文中的假说.     

Firm Size and Innovation in European Manufacturing

The paper investigates the differences between small, medium-sized and large firms regarding their performance in the introduction of new products and processes. After a review of the relevant literature, two models are proposed and tested in search for different business strategies and innovation inputs connected to product and process innovations. The empirical analysis uses innovation survey (CIS 2) data at the industry level for 22 manufacturing sectors, broken down in three firm size classes, for eight European countries. Special attention is devoted to tackling the issues of possible endogeneity of the regressors and of unobserved sectoral heterogeneity. The results – strengthening the findings of previous studies – show that product and process innovations, though having some complementarities, are associated to different innovative inputs and strategies pursued by firms. Systematic differences also emerge between the behaviour of large firms and SMEs.      

Marketing Capabilities and Firm Performance: A Hierarchical Model

The resource based theory of the firm (RBV) is briefly reviewed together with its recent application in the marketing literature. Significant contributions by Webster (1992) and Day (1994) are identified and an integration of the two presented as a hierarchical model of marketing capabilities. Three research propositions concerning the relationships between marketing capabilities and performance are developed and tested empirically in the transition economies of central and eastern Europe. In line with expectations from the theory of the RBV, higher order marketing capabilities are seen to be more important than operational capabilities in explaining superior competitive performance. The overall model is shown to be a helpful conceptualization of marketing capabilities and a number of issues for further research are identified.     

Customs-related Transaction Costs,Firm Size and International Trade Intensity

customs are generally perceived as a time-consuming impediment to international trade. However, few studies have empirically examined the determinants and the impact of this type of government-imposed transaction costs. This paper analyses the role of firm size as a determinant of customs-related transaction costs, as well as the effect of firm size on the relationship between these costs and the international trade intensity of firms. The results of this study indicate that customs-related transaction costs repress international trade activities of firms, even at low levels of these costs. The paper identifies transaction-related economies of scale, simplified customs procedures and advanced information and communication technology as main determinants of customs-related transaction costs. It is shown that when these factors are taken into account, firm size has no effect on customs-related transaction costs. Policy implications are considered for firm strategy and public policy.
