改革开放初期中国证券市场演进的历史分期

对改革开放初期中国证券市场演进的历史分期,学术界存有较大分歧。本文认为,该阶段的主题是“复苏和起步”;其上限为1980年,下限为1991年。依据发行和流通证券的数量变化和品种差异,复苏和起步阶段可划分为复苏、起步、曲折三个时期,呈现出5年—4年—3年的时段变化特征。论文说明了阶段主题界定、上下限判断、分期标准的史实依据与理论逻辑。     

市场拓展、报酬递增与区域分工——以“义乌商圈”为例的分析

基于发达国家工业化进程历史与现实观察的"专业市场消亡论",与义乌中国小商品城市场二十多年快速发展的现实并不相符。本文采用一个拓展的新兴古典经济学分工模型,结合空间经济学的基础—乘数模型,分析了在规模报酬递增前提下,义乌中国小商品城市场存在与发展的根本原因是由于其提供了一条形成跨区域分工协作网络——"义乌商圈"的有效路径,并论述了在这一过程中多方均能获益的内在机理。与原有研究义乌市场和"义乌模式"的文献相比,本文的创新之处在于将义乌市场置于跨区域分工协作网络的核心地位来加以研究。     

分工演进对贸易政策的影响分析——基于交易成本的考虑

贸易政策同贸易理论是紧密联系在一起的.引入交易成本来分析分工演进对贸易政策的影响,不考虑交易成本条件下,贸易自由对于分工演进的国家是有利的;考虑交易成本条件下,随着分工演进,国家之间更加倾向于贸易谈判,最终结果为贸易自由化.但是由于各国交易效率不同,交易效率高的国家在贸易中获得的利益更多,而交易效率低的就会实行更多贸易保护.因此,我国需要降低交易成本,加强分工演进的速度,处理好国际之间的贸易摩擦.     

肯尼亚基苏木铁路枢纽分工布局研究

肯尼亚内马铁路二期引入基苏木后,将与既有米轨铁路共同形成基苏木铁路枢纽,形成基苏木铁路枢纽内各铁路系统功能分工布局。基于基苏木铁路枢纽构成,结合既有米轨铁路现状、城市功能规划及客货运量分析,提出基苏木铁路枢纽客货分设方案和客货合设方案,经比选推荐采用客货分设方案;同时,提出港区支线接入基苏木北站南侧接轨和北侧接轨方案,经比选推荐采用南侧接轨方案。基苏木铁路枢纽分工布局符合基苏木城市功能和规划,有利于形成基苏木地区的综合交通枢纽。     

Divisionalization and franchising incentives with integral competing units

Existing game-theoretic models of divisionalization and franchising treat each firm's number of competing units as a continuous variable. We account for the integer constraint on divisions, and show that the continuous case reasonably approximates the equilibria of the discrete game.     

中国城镇化必须走集约型发展之路

贯彻落实科学发展观,统筹城乡区城协调发展,改善城乡二元结构,必须继续推进城镇化健康协调发展.在新的历史时期,推进城镇化必须更加重视集约发展,不断提高城镇经济容积率、人口容积率和公共基础设施利用率,通过调整产业结构、加强城市规划和完善行政区划结构等手段促进城镇化集约发展.     

The exchange paradigm of constitutional economics: implications for understanding the third sector

This paper reconsiders the exchange paradigm of constitutional economics from the perspective of the theory of the division of labor. According to this theory, human wants can be satisfied by two basic mechanisms—exchange and self-sufficiency. The exchange paradigm of constitutional economics emphasizes the former mechanism while neglecting the latter. Building on major economic theories of the third sector, it is argued that the latter mechanism is more helpful than the former in explaining the existence of third sector organizations. The paper concludes by discussing implications of this argument for the further development of constitutional economics.      

Does the relationship between income and child health differ across income groups? Evidence from India

This study explores the relationship between child health and socioeconomic status (health-income gradient) using the Indian Human Development Survey-II (2011-12) for children up to 5 years of age. Unlike previous studies our empirical analysis allows the gradient to vary across different income intervals using linear and cubic spline regressions. We use objective measure of child health - height-for-age Z-scores and find that an increase in income, on an average leads to reduction in prevalence of stunting. We also find differential effect of income on health across the income distribution with no effect of income on child health for very poor households. Further we explore underlying factors explaining the gradient and find that maternal health, housing quality, sanitation, non-infectious environment, media exposure to women and a safe neighbourhood are transmission channels that affect child health and together they explain almost 40% of the overall income effect. One of the major implication of our findings is that any policy to increase income of poor households should be complemented with a health policy designed specifically towards children as poor households are less likely to allocate additional income to child health.
