中部新兴城市群同城化视域下人口空间动态的诉求机制与动因机理

The Demand Mechanism and Motivation Mechanism of Population Spatial Dynamics on the Perspective of the Cities’ Synchronization of the Emerging Urban Agglomeration in Central China

中部地区新兴城市群是以太原、郑州、合肥、武汉、南昌、长沙为核心的太原城市群、中原城市群、皖江城市带、武汉城市圈、鄱阳湖经济区、环长株潭城市群。随着“半小时”综合交通网的完善以及中心城市与周边区域之间的人口、资源、信息、资金等要素往来日益频繁,已形成太榆、郑开、合淮、汉孝、昌九、长株潭等同城化区域。本文通过近十年的时间序列数据对比,从经济社会发展、区域交易费用、区域制度软环境等方面解析其同城化发展态势给人口的空间行为过程与模式带来的新诉求与动因机理。

The emerging urban agglomeration centered on Taiyuan, Zhengzhou, Hefei, Wuhan, Nanchang and Changsha in the central region is the Taiyuan urban agglomeration, Central plains urban agglomeration, Wanjiang urban belt, Wuhan urban circle, Poyang lake economic zone, Chang-sha-Zhuzhou-Xiangtan urban agglomeration. With the improvement of “half an hour” comprehen-sive transportation network and the increasingly frequent exchanges of population, resources, information and capital between the central city and surrounding areas, Taiyu, Zhengkai, Hehuai, Hanxiao, Changjiu, Changzhutan and other cities’ synchronization areas have been formed. This paper analyzes the new demands and motivation mechanism of the spatial behavior process and mode of population brought by the development trend of cities’ synchronization from the aspects of economic and social development, regional transaction costs and regional institutional soft en-vironment based on the comparison of time series data in recent ten years.
