城镇群空间结构与要素集聚

依据城镇化发展过程中要素空间集聚理论，展开区域经济发展的空间经济结构研究。通过城市引力、克鲁格曼指数计算，比较分析城镇群内部城市吸引力和城市产业分布的差异性，通过人口与生产空间分布集中度指标和不一致系数的测算，分析了山西省城镇群空间要素集聚效应。研究表明，山西省的城镇群规划与要素空间集聚趋势整体一致，城市间产业分工体系基本形成，城镇群的要素集聚效应明显，但人口与生产分布仍存在不一致性。研究认为，山西省城镇群发展应该继续明确各城市的产业分工和特色，引导劳动力和资本要素的合理流动，实现人口与生产空间分布的一致。     

FDI facilitated by agglomeration economies: evidence from manufacturing and services joint ventures in China

The open door policy of China’s economic reform since the 1980s has attracted heavy foreign direct investment (FDI) flows into China and especially to Guangdong (particularly the Pearl River Delta region, PRD) and induced significant economic growth during the past two decades. While there exist various classical theories of FDI in attempting to identify the determinants of FDI inflow and to explain the behavior of FDI flows, limited attention has been given from the perspective of agglomeration effects generated by a core-periphery (CP) relation.This paper intends to study the impacts of agglomerations on FDI inflows in the context of Krugman’s CP relation (1991) by investigating (1) the formation of a CP relation via gravity model analysis; (2) whether different types of industry FDI flows will respond differently in the CP-system, given agglomeration effects; and (3) whether FDI origin and firm scale matter in affecting FDI flows.A database consisting of a population frame of 37,742 firm-level manufacturing and services joint ventures investing in Guangdong in 1998 was used. Empirical results show that the agglomerations of the CP relation have affected FDI flow patterns. While both manufacturing and services FDI and sources of investment responded differently to the impacts, smaller firms were found more responsive to the CP-agglomeration settings regardless of FDI by industry type and by source. The significance and implications of the CP-system to further facilitate FDI in the region are discussed.     

Agglomeration Effects versus Policy Effects: The Case of the Electronics Industry in Malaysia

The present study analyses investments within the Malaysian electronics industry in 1991 to assess the effectiveness of development policy in light of strong agglomeration effects in the electronics industry. We find that agglomeration and the use of industrial estates as development policy have had positive effects on firms' location choice. However, agglomeration has a much larger effect than industrial estates. In addition, we find that the marginal effect of industrial estates is positively correlated with the degree of agglomeration. This suggests that improvement of problems of regional inequality by industry estates would be very difficult in reality.     

一个培育我国外贸新增长点的设想--发展环渤海区域外贸城市群

对外贸易的拉动作用是实现我国十六大经济增长目标的重要保证。但是，反观当前的国内外环境，我国进出口贸易的发展遇到了诸多困难。欲解决这些问题，必须进行制度创新，其中培育城市群是一种可行的办法。而环渤海区域以其特有优势，成为培育对外贸易城市群的首选。为此，我国需要在环渤海区域大力发展高新技术产业，培育产业集群，引导民营企业发展，以及发挥政府的政策作用。     

企业空间集聚的成因分析

企业空间集聚是当今世界区域经济发展的重要特色。本文从同行业和不同行业两个角度分别探讨了企业空间集聚的成困,并实例分析了徐州市金山桥开发区企业集聚体的形成与发展。     

煤炭资源型城市聚集经济与城市化水平研究

运用可变权系数综合评价模型对2002年中国煤炭资源型城市城市化水平进行测度;基于1999～2002年度煤炭城市面板数据,应用随机效应模型估计煤炭城市聚集经济水平;结果表明,我国煤炭城市城市空间经济结构效率和其城市化水平并不具有正相关性,许多城市化水平相对较高的煤炭城市的聚集经济较差,并没有显示出城市化经济的优势.     

长三角城市群产业一体化发展研究——城际战略产业链的视角

伴随着城市群的发展,城市间产业分工开始向产业链分工方向发展。各城市按照产业链的不同环节进行专业化分工,形成不同类型和层次的城际产业链,城市间基于城际产业链尤其是城际战略产业链的分工协作关系加快了城市群产业一体化的进程。本文构建由产业战略力维度和城际链接力维度构成的城市群产业一体化发展模型,利用该模型确定长三角城市群三大城际战略产业链,依据产业链各环节的优区位要求,对三大城际战略产业链在城市群地区进行空间布局。最后指出,加快城市群产业一体化的关键是,城市群城际战略产业链类型的正确选择和城际战略产业链环节的合理布局和优化组合。     

产业空间集聚的理论发展

产业空间集聚的本质是经济行为主体相互选择的结果.从主体策略选择的角度对产业空间集聚的理论研究进展进行诠释,体现了行为主体在空间区位上的策略均衡,也体现了空间经济理论的研究传统.作为经济干预主体的政府,其介入影响着微观经济主体的空间策略,从这一理论角度出发,阐述转型发展中经济资源的空间配置问题具有特定的现实意义.     

论旅游地的集聚效应

旅游地的集聚在带来经济效应的同时，也可能产生集聚不经济现象，分析了旅游地集聚效应的形成机理和旅游地的集聚效应，并对如何引导和培育旅游地的集聚经济效应进行了分析。     

溢出效应、边界选择与产业集聚测度

产业集聚程度的测度结果受所选产业加总水平与地理单元大小的影响,后者应以集聚过程中溢出效应的产业边界与空间边界为基础。当前产业集聚测度研究普遍存在产业加总水平与地理单元选择过大的问题,本文试图研究在这种情况下测度结果是否存在偏差,偏差的系统性、方向、大小和影响因素,以及有偏的测度结果对集聚经济研究的影响等。结果表明,超出空间边界或产业边界的测度结果将显著偏低,并导致对集聚经济的低估;按省测度的区位基尼系数比按市测度平均低了近40%,两位数产业的区位基尼系数通常低于其所含三位数产业的区位基尼系数的均值,甚至最低值。
