我国妇女就业的问题与对策

一、我国妇女就业的现状 (一)女性就业率高 新中国的女性就业状况比旧中国有巨大进步。据1940年原国民政府统计局的局部调查,当时10岁以上女性人口中,有正当职业的在不同地区只占1％-10％。50年后,1990年,全国人口普查,妇女就业率上升到73％,其中城镇妇女就业率     

论环境标准差异对企业竞争力的影响及对策

环境标准产生于环境管理的需要,依内容而分为环境技术标准与环境管理标准。不同经济发展水平的国家在环境技术标准上存在差异,这种差异从成本和市场两个方面对企业竞争力产生重要影响,其总体效应取决于消费者的偏好和企业战略。在现实中,偏低的环境技术标准虽使我国企业获得了短暂的贸易优势,但不利于长期的持续发展。要打造长久的竞争优势,必须选择最优环境技术标准,并大力采用ISO 14000系列管理标准。

A theory of mutual migration of polluting firms

Abstract.  Suppose that governments care about their tax revenue and local firms have some say in environmental regulations. Then, the level of employment and environmental compliance may be negotiated. We find that firms located in different countries can improve their threat‐point payoffs by mutual migration. This in turn affects the negotiated output/employment and environmental regulations, which causes profits to increase if the firm's threat‐point payoff is higher than that of the local government. The model predicts that pollution‐intensive firms or firms with highly inelastic demands are more likely to move out. Increases in the government's valuation of the environment, or in the degree of globalization also cause mutual migration of dirty firms. The effect of a government caring about consumer surplus leads to a lower pollution tax, reducing firms' incentives to move out. JEL classification: F2, Q0

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)     

金融深化、FDI溢出效应与区域经济增长:基于1997～2004年省际面板数据分析

本文构建了一个包含金融深化程度变量的内生增长模型,通过设定一个金融深化程度函数,并将其引入最终产品部门的生产函数,证明了金融深化程度是FDI技术溢出效应的重要因素。采用我国1997~2004年31个省市的面板数据的实证结果也表明,金融深化程度是FDI溢出效应的决定因素之一。从实践来看,相对于我国现有的外资规模,我国的金融深化程度滞后是造成FDI溢出效应为负的原因之一。而且,金融深化程度的不同也是造成FDI溢出效应跨区域差异和阶段性变化的重要原因。文章最后针对如何推进金融市场化进程以获取正向FDI溢出效应提出了政策建议。
