城市群竞合问题研究

近年来,我国城市群发展迅速,但竞合水平较低。从总体来看,我国城市群竞合主要存在竞合意识缺乏、竞争多于合作、形式大于实效、重硬件轻软件等问题。要提升我国城市群的竞合水平,必须加强竞合制度的建设,改善软环境及参与国际竞合,使竞争与合作相互促进,推动城市群经济健康发展。

“钱才”集聚论与我国金融中心建设

本文在梳理金融中心相关文献的基础上,提出金融中心的钱才集聚论,认为金融中心实质上是金融资源相对集聚的场所,而金融资本和金融人才的集聚则是各类金融资源集聚的基础。我国金融中心建设需要把握金融资源集聚的关键环节,创造良好的环境,促进钱、才等金融资源集聚。     

从保护耕地的视角推进武汉城市圈农村土地合理流转

随着我国经济快速发展和城市化进程的加快,农地流转已成为必然趋势。另外,城市圈作为一种新型城市化发展道路,已成为我国城市化进程中的战略选择。由于历史和现实的原因,特别是在现行的土地制度下,推进城市圈农地流转工作难度较大,问题较多。本文在分析武汉城市圈农地流转的现状的基础上,指出了城市圈内农地流转存在的问题,并结合各地区农村土地改革中出现的农地流转创新模式与经验,从保护耕地的视角,提出了推进武汉城市圈农村土地合理流转的对策和建议。     

Where Should the Elderly Live and Who Should Pay for Their Care?*

We consider a model with a population consisting of earners and retired persons; elderly care is publicly provided. There is one big city, where congestion effects and agglomeration forces are at work, and a number of small villages. We show how the externalities related to population mobility lead to an inefficient spatial distribution of earners and retirees, and we characterize the second‐best solution. Decentralization of this solution in a fiscal federalism structure requires the use of taxes and subsidies proportional to the number of earners and retired persons living in the city and the villages.     

Firm productivity and agglomeration economies: evidence from Egyptian data

This paper attempts to shed the light on the nexus between firms’ productivity and economies of agglomeration in Egypt. Using a large dataset of firms in 342 firms’ four-digit activities in 27 regions (62,108 firms), we introduce three measures of agglomeration which are urbanization or firm diversification measured by the number of firms by governorate, localization and specialization measured by the average productivity by governorate and sector (generating externalities and knowledge spillovers) and finally competition measured by the number of firm operating in the same governorate and the same sector. We find strong evidence for the existence of agglomeration in Egypt after controlling for firm age, location, economic activity and legal status. In the Egyptian context, productivity spillovers gained from agglomeration measures outweighed the negative effects of competition implied by congestion. The latter is chiefly due to the lack of good infrastructure. When regressions are run by firm size, location and activity, our main findings show first that micro and small firms are more likely to benefit from localization and diversification compared to medium and large firms. Service firms benefit more from high level of diversification while manufacturing firms gain more benefits from knowledge spillovers and specialization in Egypt.

交易费用视角下的金融集聚效应

从交易费用视角看,产业集聚可以扩大市场广度,增加市场深度,从而拓展市场范围,促进分工的进一步发展并实现分工的利益.金融集聚作为产业集聚的一种形式,通过和当地服务业、制造业的互动拓展了金融产业的市场广度;通过金融企业之间的竞争合作关系增加了金融产业的市场深度,对区域金融产业产生积极的集聚效应,促进了地区金融业的良性发展.     

成都市产业集聚效应实证研究

集聚经济在城市与区域经济发展中占有核心地位，直接体现出城市与区域空间结构合理性、经济效益以及竞争力。本文通过不变替代弹性生产函数计算，发现成都市内部集聚经济、城市集聚经济在近几年有所发展，总体集聚效应呈上升趋势，但布局集聚经济略显微弱，工业总体集聚效应良好。     

论长株潭“两型”社会建设视野下生态道德意识的培养

长株潭＂两型＂社会建设的本质就是实现生态化发展,而实现生态化发展最根本最有效地手段是提高全体社会成员生态道德意识。为此,要从政府决策宏观层次、企业中观层次和社会公众微观层次三方面来提高生态道德意识,同时,还应发挥学校教育在环境道德意识培养中的特殊作用以及加强环保部门组织协调作用。
