城镇社会保障的“本地—外来”分割与外来人口社会保障缺失

过去对城市社会保障缺失的学术关注集中在农民工并从城乡分割来解释。本文认为,在现行的社会保障地方分权体制下,存在着城;市社会保障城的“本地——外来”分割,表现为外来人口,包括外来非农人口的社会保障缺失;社会保障地方分权的背景是城乡和区域发展不平衡。对北京市调查数据的分析显示了社会养老保险参保率的“本地—外来”差异。

外商直接投资对中国贸易影响的动态分析

国际贸易理论认为,国际投资有可能替代投资国对东道国的贸易,也有可能促进双边贸易的发展。本文使用1984～2004年中国与14个主要投资经济体的贸易和投资数据,发现改革开放以来各投资经济体对华投资促进了中国对外贸易的增长,但是投资与双边贸易的关系发生了动态变化。1992年以前投资对贸易的促进作用非常明显,1992～1998年投资的边际贸易倾向迅速减弱,1999年后进一步降低。除了中国前5大投资经济体以外,1999年以后其他投资经济体的对华投资出现了明显的贸易替代作用。

Fixed Exchange Rates and Disinflation in Emerging Markets: How Large Is the Effect?

We examine developing countries which have institutional quality ratings for the effects of exchange rate rigidity on inflation. The level of institutional development exerts no effect on the impact of currency regimes. However, the interaction of institutional quality and exchange rates has, in the most plausible specifications, a negative impact on inflation. This suggests that fixed exchange rates exert at most a contingent effect on inflation, and indicates that countries in Eastern Europe and Latin America contemplating currency pegs would be better off improving institutional quality prior to adopting the euro or dollar and expecting a large subsequent disinflationary effect.

Theory and practice of value management and its innovation for natural resources from the perspective of sustainable development

The supreme obstacle for sustainable development of natural resources is the scarecity, bottleneck. So how to promote the sustainable utilizing and increase the using efficiency of natural resources is worth studying. This paper suggests that we should improve the model and means of evaluating method and value management based on th~ theory of natural resource compensation. This paper discusses the User Cost Method based on the microeeonomicaspect which can change the evaluating method for natural resources. From the perspective of value managemen model, we should use the User Cost Method to realize the linkage and integration of micro and macro eompensation for natural resources. Based on the evaluating and aecounting idea User Cost Method, this paper presents a theo. retical framework to harmonize and link micro and macro compensation for natural resources. At present, we should seek the new approach and method to manage natural resources, so can we realize the capitalization managemen focusing on the vahte management for natural resources.
