Some Comments on Embeddedness, Knowledge Transfer, Industry Clusters and Global Competitiveness

This paper develops a dynamic theoretical framework for global competitiveness, which describes the relationships among organizations in an industry cluster. The spiral for knowledge transfer, culture variables and embeddedness influence knowledge transfer. Embeddedness and knowledge transfer are the key determinants of industry clusters that lead to global competitiveness. Industry clusters are characterized by external economies, generalized reciprocity and flexible specialization.     

On transaction efficiency and China’s Urban-Rural disparity

It is recommended for economists to examine China’s Urban-Rural disparity from the perspective of transaction efficiency, in that it can provide us with a systematic explanation to both the cases of different countries and development stages. China’s Urban-Rural disparity is special and virtually a demonstration of its special transaction efficiency structure. Exploration of China’s Urban-Rural disparity from such perspective indicates that, different from those in countries with a market economy, China’s case involves many exogenous and contrived factors. Therefore, the solutions are to improve the whole transaction efficiency in the economy, which includes eliminating its regionally unfavorable policies and institutions, and enforcing more favorable and regionally balanced institutional reforms. __________ Translated from Fudan Journal (复旦学报, Social Science Edition), 2006, (1) (in Chinese)     

The impact of job embeddedness on innovation‐related behaviors

It has often been argued that low turnover leads to less innovation in organizations, not only because fewer job vacancies are available for outsiders with new ideas, but also because longer‐tenured employees might be more resistant to change. In this study, we propose that job embeddedness may actually strengthen employees' motivation to generate, spread, and implement innovative ideas in organizations. In a longitudinal study with a diverse sample, we found that job embeddedness was positively and significantly related to innovation‐related behaviors, even after controlling for demographic variables, the job attitudes, and the job perceptions that are frequently associated with job embeddedness. In addition, we found some support for the proposed moderating effects of career stage; that is, the relationship between job embeddedness and implementing innovative ideas was stronger for individuals in the mid‐ and late stages of their careers than for those in the early stage of their careers. This article concludes with directions for developing future theory. © 2010 Wiley Periodicals, Inc.     

中国城乡二元结构的转换途径——基于分工动态循环演进的视角

在分工理论的基础上,首先构建了“分工动态循环演进”的概念框架,并在此概念框架下对城乡二元经济结构的成因进行理论分析,得出企业和市场发育程度不同是导致城乡二元经济结构产生的根本原因这一不同于传统二元经济理论的结论。之后,采用我国1980—2011年的时间序列数据验证了上述结论,并得出,我国要顺利实现二元结构转换,关键是要通过农业产业化、农业促进制度和普惠金融力推农村企业和市场发展,以企业和市场的发展带动农村分工深化和劳动生产率水平提高。     

企业私有化程度提高则社会环境会变差？

从企业私有化角度出发,构建二元经济理论模型和实证模型分析私有化对环境污染的影响。理论研究发现,由于城市部门资本密集程度高于农村部门,而且如果农村劳动者从环境改善中获得的边际效用小于城市劳动者从环境改善中获得的边际效用,那么提高私有化导致单位产出污染排放减少时会引起：（1）劳动和资本要素会向城市流动,城市工业部门产出增加;农业部门由于劳动和资本流出而导致产出减少,即城市扩张而农村收缩;(2)城市地区的失业总人数会增加;(3)私有化导致单位产出污染排放减少的效应大于工业产出增加导致污染排放增加的效应,最终导致社会环境改善,但如果私有化导致单位产出污染排放增加,则会得出相反的结论。实证结果表明：企业私有化水平提高有利于降低单位产出固体废物、废水、二氧化硫和烟尘等污染物的排放,资本投入也有利于降低单位产出污染物的排放。
