领导风格与员工工作态度——互惠和信任的中介作用的实证研究

互惠和信任是社会交换的普适准则。本文基于社会交换理论，以中国境内各类企业972位管理人员为样本，试图研究领导风格与员工工作态度之间的关系，尤其是组织与员工间的互惠和员工的组织信任在其中的中介作用。在初步研究的基础上，本文对变革型领导、事务型领导、广义互惠、平衡互惠、员工的组织信任、组织承诺和离职意愿各概念进行了系统的探索性分析和验证性分析，接着检验了这七个核心概念的区分效度。研究结论表明：（1）变革型领导不仅直接对员工的组织信任和组织承诺产生作用，而且通过组织对员工的广义和平衡互惠使员工产生对组织的信任，从而提高员工的组织承诺和降低员工的离职意愿；（2）事务型领导仅仅通过互惠对员工的组织信任和组织承诺产生作用；（3）广义互惠直接影响员工的组织承诺，平衡互惠通过组织信任影响员工的组织承诺。研究结论告诉我国企业领导者，首先，尽可能锻炼自己，努力成为变革型领导者。其次，要努力塑造互惠和信任的企业文化，并且特别着重于建设广义互惠的企业文化和制度环境。     

技术资本价值增值效应：基本内涵、关键因素与政策取向

作为企业知识创造与应用的重要途径，技术资本具有显著的动态竞争优势、规模经济、范围经济和速度经济等效应，实现了技术研发、生产与市场的结合，促进了技术的有效转化及资本价值的增值。技术资本属性、技术体制等是影响技术资本价值增值效应的关键要素。旨在促进技术资本化的政策，应以促进这些要素积极效应的释放为重点。

中国改革时期省际生产率增长变化的实证分析(1979-2001年)

中国经济的发展是否正在背离比较优势的原则?今后中国是否要加快经济增长模式的转变?该文试图通过对省际全要素生产率(TFP)及其组成部分的测算,从技术效率和技术进步这两个不同的方面来考察中国改革开放以来的TFP增长性质和近几年来的变化趋势,以便为相关政策讨论提供一些实证依据.我们的研究结果表明,中国经济增长在1978-1995年期间经历了一个TFP高增长期(为4.6%);而在1996-2001年期间出现低增长期(为0.6%),其变化的具体特征为:技术进步速度减慢、技术效率有所下降.     

Strategic Reaction of Vertically Integrated Firms to Downstream Entry: Deterrence or Accommodation

The purpose of this paper is to analyze strategic behavior of vertically integrated firms when there is downstream entry, taking into account the balance between competition in the market and competition for the market. This analysis can serve to explain diverse distributional structures, including the coexistence of vertically integrated firms and independent retailers. And it shows that the relative efficiency of downstream entrants and the level of competition among incumbents are two major factors in determining equilibrium configuration.     

Using data envelopment analysis approach to estimate the health production efficiencies in China

By using Data Envelopment Analysis approach, we treat the health production system in a certain province as a Decision Making Unit (DMU), identify its inputs and outputs, evaluate its technical efficiency in 1982, 1990 and 2000 respectively, and further analyze the relationship between efficiency scores and social-environmental variables. This paper has found several interesting findings. Firstly, provinces on frontier in different year are different, but provinces far from the frontier keep unchanged. The average efficiency of health production has made a significant progress from 1982 to 2000. Secondly, all provinces in China can be divided into six categories in terms of health production outcome and efficiency, and each category has specific approach of improving health production efficiency. Thirdly, significant differences in health production efficiencies have been found among the eastern, middle and western regions in China, and among the eastern and middle regions. At last, there is significant positive relationship between population density and health production efficiency but negative relationship (not very significant) between the proportions of public health expenditure in total expense and efficiency. Maybe it is the result of inappropriate tendency of public expenditure. The relationship between abilities to pay for health care services and efficiency in urban areas is opposite to that in rural areas. One possible reason is the totally different income and public services treatments between rural and urban residents. Therefore, it is necessary to adjust health policies and service provisions which are specifically designed to different population groups. __________ Translated from Jingji Yanjiu 经济研究 (Economic Research Journal), 2006, (7): 92–105     

Explaining momentum profits with an epidemic diffusion model

We show that information diffusion is a function of its dissemination and assimilation. Whereas dissemniation is a function of observable factors such as volume and price volatility, assimilation is dependent on unobservable factors such as the usefulness and reliability of information. We find that buying low volume (or low volatility) past losers and shortselling low volume (or low volatility) past winners generates a positive net return across the entire sample period and especially during bear markets. Second, buying high volatility past winners and shortselling high volatility past losers generates a positive net return, especially during bear markets.
