论废旧家电回收利用主体的责任--《废旧家电及电子产品回收处理管理条例》(征求意见稿)之评析

废旧家电的回收利用、再商品化已经成为世界的潮流，国外许多国家相继通过法律来引导并建立完善的废旧家电回收利用体系。我国新近出台的《废旧家电及电子产品回收处理管理条例》(征求意见稿)也对回收利用行为进行了规范。要想建立并完善废旧家电的回收利用体系．就必须明确各责任主体包括生产者、销售商、进口商、消费者，在废旧家电回收利用中所应承担的责任。通过对国外立法的比较分析，以及对《征求意见稿》中关于废旧家电回收主体承担责任有关规定的评析，在对该征求意见稿肯定的同时，提出包括消费者付费、责任比例细化等建议。

Money and specialization

Summary.  This paper examines the relationship between specialization and the use of money in two versions of the search-theoretic monetary model. The first version establishes a surprising result that specialization is more likely to occur in a barter economy than in a monetary economy. The result is reversed in the second version where a different specification of preferences is adopted to limit the scope of barter. This contrast between the results provides a concrete illustration of the general argument that money encourages specialization only when it enlarges the extent of the market.

The effects of transition on the distribution of income in China

Using two large samples for 1988 and 1995 we decompose the Gini coefficient of household income according to type of income with the purpose of analyzing reasons for the rapid increase of inequality. The results show that the change in relative size of money income and its changed profile are found to be the major processes behind the rapid increase of income inequality in rural China. Changes in housing allocation and an increased number of retirees in combination with higher benefits have made inequality increase in urban China and in China as a whole.

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.
