中文摘要: 城市群是实现我国区域总体发展战略的重要载体。本项目组从新经济地理学与新古典经济学的理论视角,建立一个产业聚集-城市聚集理论分析框架,明确提出城市群经济的概念,解释了城市彼此空间临近即城市聚集也会产生正外部性,城市之间的分工协作会带来收益,这是对现有城市群理论的有益拓展与补充。本项目组还基于已初步建成的长三角城市群经济空间数据库,运用先进的空间统计、空间计量方法和GIS空间分析技术,创新性地建立一个交通网络、城市聚集对城市群经济增长的半参数空间计量估计模型进行实证研究,这为分析交通网络、城市聚集对城市群经济的影响提供了新方法、新技术与新视角。在长三角城市群内交通网络、通勤就业、居民就业、产业布局加快同城化趋势下,本项目就如何提升交通网络的正外部性,以及完善城市等级体系、发挥城市聚集效应、提升同城化水平给出具体政策建议,这具有重要的现实意义。

英文摘要: Megalopolises are important carriers for implementation of the overall regional development strategies of our country. From the theoretical perspectives of new economic geography and neoclassical economics, this research develops a theoretical framework of industrial agglomeration-urban agglomeration, defines clearly the concept of megalopolis economy, and points out that spatial adjacence of cities i.e. urban agglomeration can also creates positive externalities, and specialization and cooperation between cities create benefits, which makes expansion and supplementation to existing megalopolis theory. Based on preliminarily built Yangtz Delta Megalopolis Economy Spatial Database, and using spatial statistical and spatial econometric methods and GIS spatial analytical techniques, this research creatively develops a semi-parametric spatial econometric model to empirically study the effects of transport networks and urban agglomeration on megalopolis economic growth, thus provides new methods, techniques and perspectives for analyzing the effects of transport networks and urban agglomeration on megalopolis economy. Under the trend of accelerated integration of transport networks, commuting, employment, and industrial distribution in the Yangtz River Delta megalopolis, this research gives policy suggestions for increasing positive externalities of transport networks, improving urban hierarchy, exploiting urban agglomeration effects, and promoting urban integration, which has great practical significance.
