双边市场经济学研究的进展

双边市场是现代经济中的重要组成部分，而国外对双边市场理论的研究早已蔚然成风，因此我们开展相关研究具有重要的理论和现实意义。本文分别从企业战略、平台竞争及福利分析、反垄断问题、复杂双边市场、最终用户有议价能力时的有关问题和实证研究等六个方面对有关研究进行了介绍，最后是简单的总结。     

论城乡网络化发展与文化整合--城市化的后现代视点

在现代主义语境里，城市和乡村被割裂为“城市——中心、乡村——边缘”的二元空间。而20世纪70年代之后，后现代思潮开始兴起和蔓延，其思想体系中包含的多元差异性、整体性、生态观和可持续发展等理念为城乡发展提供了新的思维范式和价值取向。本文将后现代主义引入城乡发展理论框架，以后现代视点重新审视城市与乡村的关系，提出空间整合和文化整合的城乡发展新取向，旨在为谋求后发展国家城市化的独特模式提供一种新观念和新视角。     

Education, Work and Wages in the UK

Abstract. This paper is concerned with the relationship between education, wages and working behaviour. The work is partly motivated by the sharp distinction in the literature between the returns to education and the effect of wages on labour supply. Education is the investment that cumulates in the form of human capital while labour supply is the utilization rate of that stock. Yet, variation in education is usually the basis for identifying labour supply models – education is assumed to determine wages but not affect labour supply. Moreover, it is commonly assumed that the private rate of return to education can be found from the schooling coefficient in a log-wage equation. Yet, the costs of education are largely independent of its subsequent utilization but the benefits will be higher the greater the utilization rate. Thus the returns will depend on how intensively that capital is utilized and we would expect that those who intend to work least to also invest least in human capital. Indeed, the net (of tax liabilities and welfare entitlements) return to education will be a complex function of labour supply and budget constraint considerations.
Here we attempt to model the relationship between wages, work, education and the tax/welfare system allowing for the endogeneity of education as well for the correlations between the unobservable components of wages and working behaviour. We use the estimates to simulate the effect of a new UK policy designed to increase education for children from low-income households.     

中国区际分割影响工业竞争优势的实证分析

中国区际分割导致了市场化水平、技术效率以及资本积累的差异，从而引起各区域工业的产业竞争优势的不同，利用回归分析的结果表明：与区域的市场化指数、技术效率两个因素相比较，区域资本规模是影响区际工业的产业竞争优势的更主要的因素。

Robustness to the unavailability of data in block designs

We present general results for finding or boundingt _maxB , the maximum number of arbitrary whole blocks of observations which can be removed from a block design, and still leave all of the elementary treatment contrasts estimable. The block sizes may be larger than the number of treatments. The results are applied to BBDs, reinforced BIBDs and BBDs, BTIBDs, and a series of variance balanced incomplete block designs with two block sizes. Also given for most of these designs, are results fort _max, the maximum number of arbitrary, scattered observations that can become unavailable, and still leave all of the elementary treatment contrasts estimable.The work was undertaken while Dr. Whittinghill was visiting Ohio State University, and supported by a grant from the Natural Sciences Division, Colby College, Waterville, Maine.

本文介绍了以德国为代表的西方国家的财税体制和行政体制，分析了行政体制与财税体制相分离的情况，指出了在市场经济条件下提高财政效率的办法，并在此基础上批评了试图重新划分行政区划来提高财政效率的设想。     

江南乡村精英的百年变迁

一、传统社会:士绅作为非官方的精英阶层,具有压倒性的影响力 首先,我们应当了解乡村社会的基本组织形态."以集镇为中心,一般包括15-20个村庄,组成了构筑经济层次的基本单位."即村落以集市或市镇为中心形成网状的自我体系,是周围农民的社会活动的基本范围.它的市场圈、宗教圈、婚姻圈等都是重叠的.     

基于地理学对"三江源"生态难民形成机制的分析

本文围绕“三江源”日益恶化的生态环境及由此引发的生态难民问题,从地理学的角度进行了综合分析,明确提出独特的自然环境系统和现代环境的变迁给源区牧民提供了极其狭小的空间,而人类活动中传统的生产方式、现代价值取向的变化、社会管理的失误以及落后的经济发展水平,无限制的对自然的索取,超越了环境系统所能承受的阀值,人类不得不听任自然的“安排”。因此,应通过合理规划,积极妥善地安置源区生态难民;调整产业结构,积极发展源区经济;科学管理,有计划地节制外来流动人员;发展教育,构建与源区生态相适宜的生态文化,实现区域可持续发展的“双赢”目标。
