对我国医药企业自主创新演化机制的分析

自主创新是当前商业界和学术界研究比较热的话题。政府相应地制定了一系列的政策和法规来鼓励企业进行自主创新。在这种背景下,我国的医药企业也积极响应国家的政策进行自主创新。然而,医药企业创新在实际操作中的行动方向差异很大。针对这种差异,笔者将医药企业创新划分成新功能创新和新设计创新两种,并且通过对一系列的数据和资料分析后,发现我国的医药企业的创新并非实质上的自主创新即新功能创新,而是新设计创新。文中对产生这种局面的演化机制进行了分析。     

Regional Unemployment in Transitional China: A Theoretical and Empirical Analysis

The purpose of this paper is to explain the pattern of regional unemployment in transitional China. A model is developed to explore how urban unemployment in the provinces is influenced by peasants' wages, formal sector wages, and the size of the formal sector. Evidence from panel data suggests that a significant indicator of high unemployment rates is greater Urban–Rural Income Inequality within the province. The hypothesis is that the urban–rural income gap produces migration, and more rural migrants substitute for urban workers, causing further urban unemployment.Since the economic reforms began in 1978, the non-state owned enterprises have been carrying an increasing weight in the economy, and they have contributed significantly to the rapid economic growth of China. Empirical evidence shows that economic reforms have reduced unemployment. The provinces that are still heavily dependent on the state sector are therefore more likely to experience higher unemployment.

社会地位对宏观经济变量的动态影响——基于两部门搜索均衡模型的研究

本文将失业理论的搜索模型与社会地位结合起来考察社会地位的动态影响。研究发现社会地位引入效用函数等价于代表性家庭时间偏好率的降低,利用对数效用函数,得到经济系统均衡状态存在的唯一性。在均衡状态下,更强的社会地位意识意味着更高的储蓄率和资本积累,以及提供更多的社会空闲职位、更高的工资、更高的就业率、更为宽松的劳动力市场和更低的利率。     

A Note on Minimax Mixture of Distributions Free Procedure for Inventory Model with Variable Lead Time

In recent papers, Moon and Choi (1998) and Hariga and Ben-Daya (1999)considered a continuous review inventory model with a mixture of backordersand lost sales in which the lead time, the order quantity, and the reorder pointare decision variables was studied. Moreover, they also develop a minimaxdistribution free procedure for the problem. While the demands of differentcustomers are not identical in the lead time, then we can't only use a singledistribution (such as Moon & Choi (1998) and Hariga & Ben-Daya (1999))to describe the demand of the lead time. Hence, we correct and extend the modelof Moon and Choi (1998) and Hariga and Ben-Daya (1999) by considering thelead time demand with the mixture of distributions. In addition, we also applythe minimax mixture of distributions free approach to the model by simultaneouslyoptimizing the order quantity, the reorder point, and the lead time to devise a practical procedure which can be used without specific information on demand distribution.

企业间专业化分工与产业集群组织发展——基于交易费用的分析视角

从劳动的专业化分工入手,本文通过揭示产业集聚降低区域企业交易费用,指出发生在产业关联企业间而不是企业内的专业化分工是产业集群组织发展的基本动力。大量的产业关联企业在区域内聚集发展,不仅能够降低企业内生交易费用,而且能够降低外生交易费用,使人们劳动的专业化分工深化沿着大量地理接近的企业间而不是数量有限的企业内进行,从而为产业集群发展给出了一个具有新制度经济学含义的理论解释。
