基于VAR的中国农村金融发展与农村经济增长相关性研究

农村经济是我国国民经济的重要组成部分,农村金融作为经济资源配置的核心是否对农村经济产生促进作用,而经济的增长又是否对金融的发展产生反作用,这个问题一直是理论界关注的焦点问题。本文通过选取合适的农村金融和农村经济指标,建立VAR模型,利用Granger因果关系检验、脉冲响应函数和方差分解,来揭示两者之间的相关关系。     

经济发展与企业家精神的U型关系及其检验

利用国际创业观察组织提供的数据进行研究表明,经济发展水平与创业意愿存在非线性的U型关系:在谋生阶段,经济发展将带来创业精神和意愿的降低;在谋利阶段,经济发展将带来创业精神的提高.而对中国31个省市自治区2005年的截面数据进行研究发现,经济发展水平与创业意愿之间却表现出一种线性的正相关关系.这是由于国内劳动力要素从贫困地区向相对富裕地区流动、资本要素从富裕地区向贫困地区流动,从而减弱了创业的谋生动机,国内和国际市场上要素流动程度的差异导致了经济发展与企业家精神之间关系的差异.     

民营企业的政治资源与民营企业多元化投资——以中国民营企业500强为例

This paper argues that the political resources owned by Chinese private enterprises affect their diversification strategy under the context of China’s transitional economy. Based on the sample of top 500 private enterprises in 2004 in China, we find the following empirical evidence: First, political resources owned by private enterprises are positively and significantly related to their degree of diversification. Second, the possibility for private enterprises to diversify their business by entering industries under government regulation is positively related to their political resources. Third, the possibility of related diversification for private enterprise is negatively related to its political resources.

基于溢出效益的研发联盟利润分配设计

研究了如何利用利益分配方式作为激励机制,促使研发联盟成员放弃投机行为(即道德风险);对Shapley值法进行修正并以此为分配依据,设计出研发联盟的利润分配机制,以此激励联盟成员自动选择联盟最优投资策略作为自己的研发投资策略;通过理论及数值仿真算例分析证明,采用修正的Shapley值法进行利润分配,能够实现防范道德风险,促进合作研发的成功。     

论国际移民与经济发展

国际移民作为一种历史产物和社会现象,与全球经济形势、各国的经济和社会发展状况等有着紧密的联系。当今国际人口迁徙数量的增长是经济全球化的直接产物,国际移民对接受国和原籍国的经济发展和社会生活都会产生重要影响。主要发达国家在调整其移民政策的同时,趋向进一步放宽对技术移民的准入,政策趋于务实;为实现互利共赢,加强协调,尽量减少或消除国际移民的消极作用,推动全球化朝有利于共同发展方向发展,各国政府对加强移民问题国际对话与合作持更加开放和积极的态度。     

中国制度变迁和经济增长的实证分析

文章运用人工神经网络和回归的方法对我国制度变迁与经济增长进行了实证分析,并对全要素生产率增长率的波动与实际产出增长率的波动进行了比较分析。结果表明制度变迁对经济增长有显著的非线性影响,全要素生产率增长对经济增长贡献的潜力和空间很大。今后我国经济制度的变迁应致力于提高全要素生产率。     

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
