城市化释义

21世纪是“城市世纪”。中国城市化与经济增长成正比,呈现高速发展趋势。城市是人类社会经济发展的必然结果、现代文明标志及创新的载体,是政治、经济、文化、教育和信息中心,具有集聚、规模和辐射等功能效应。2000余年来,城市内涵随历史发展不断丰富。城市化一词的出现至今也有百余年历史,不同学科对城市化理解不同。其实质是一个以人为中心、受众多因素影响的复杂多变的软硬件系统化过程,是从传统向现代全面转型和变迁过程。不仅是农业人口向非农、并向城镇的聚集,而且是城镇在空间数量、区域规模、功能作用诸方面的扩大,以及城市经济关系、居民生活方式改变的过程。城市化与城镇化、农村城市化、农村城镇化及城乡一体化等相关新概念有所区别。从区位论、结构论、人口迁移论、非均衡增长论到生态学派论,从梯度推移、增长极与地域生产综合论到产业集群论的演进,体现了城市化发展理论的深化。不同学者对城市化动力机制认识不同,但在“推拉”机制上形成共识。不同阶段和同一发展阶段的不同地区,中国城市化动力机制相异,而其相同点包括:农业工业化推动、比较利益驱动、农业剩余贡献和制度变迁促进等。

Strategic Bargaining Over Child Support and Visitation

When parents divorce, child support and visitation must be determined. The 1988 Family Support Act requires all states to have child support guidelines for courts to use in determining child support obligations. However, many divorcing couples arrive at agreements without court intervention, or they simply fail to enforce the court decision ex post. Given that the guidelines provide a starting point for negotiations, couples may be able to find self-negotiated, Pareto-improving solutions. In this paper we model the bargaining process that divorcing couples engage in when coming to agreements on visitation and child support. The model suggests that individuals may arrive at agreements that are Pareto improvements for both parents but that the children's welfare may decline as a result of these self-negotiated settlements. Data from the Stanford Child Custody Study show that the changes made in child support and visitation agreements are consistent with our model in only 30 percent of the cases. Therefore, we consider alternative specifications of the model and show that both significant costs of enforcing the original agreement and alternative assumptions on parental preferences can explain these empirical results.     

当前影响和制约中国电子商务进一步发展的几个问题

当前，影响和制约中国电子商务进一步发展的主要问题集中表现在“信用缺失”问题上，它导致人们对网上交易仍心存疑虑，物流配送滞后，商品流通不畅，企业计算机应用水平不高，高水平网络人才匮乏，与电子商务相关的法规体制不够健全。为此，中国电子商务必须建立诚信长效机制，加快物流配送体系建设，构筑有效的社会物流配送系统．加快推广电子商务知识，强化电子商务人才培养，健全与国际接轨的电子商务法律体系。

中国城市化与社会结构变迁

文章从社会学角度探讨了过去30年以来中国的城市化及其引发的社会结构变迁。文章指出，在过去30年中国的城市化经历了飞速的发展，进入了快速城市化阶段，离基本城市化阶段越来越近，但由于中国独特的城乡制度以及行政管理体制，中国城市化呈现两种模式——主动城市化模式和被动城市化模式，并呈现多种城市化主体，而政府和企业则是中国城市化的主导性主体。这背后最主要的动力机制还是制度和利益，彰显出中国社会结构变迁趋势：在利益机制驱使下，中国社会渐渐地形成了城乡差别不断扩大、城市内部分化明显的利益分配格局；由于缺乏公开、公正、民主的配置机制，各个城市化主体之间的博弈大多屈从于弱肉强食的“丛林法则”，从而导致各种暴力冲突、相互仇视的问题，这在一定程度上破坏了城市社会运行秩序特别是支撑这些秩序的信任机制，显现出相当严重的合法性危机，对未来中国的城市化提出了严峻的挑战。为此，文章提出了中国未来城市化的几种可能的路径。

The availability of personal and external coping resources: Thier impact on job stress and employee attitudes during organizational restructuring

This study examines the relationships among personal coping resources, social support, external coping resources, job stressors and job strains in a sample of 110 American Telephone and Telegraph employees undergoing a major organizational restructuring. The study expanded on a model suggested by Ashford (1988) by defining another category of coping resources that employees may draw upon to deal with the stressors and strains which occur during major organizational changes. External coping resources were defined as those which provided employees with a sense of 'vicarious control' in stressful situations. Results indicated that personal coping resources, social support and external coping resources had a direct effect upon job stressor and strain levels. No 'buffering' effect of these coplng resources was found. Hierarchical regression analyses indicated that external coping resources added to the prediction of job stressors and strains even when pertonal coping resources and social support were entered first into the prediction questions.
