基于社会网络方法的长江中游城市群城镇体系空间结构研究
首发时间:2018-01-10
摘要:随着长江中游城市群综合经济实力的增强,区域内的城镇经济联系更加紧密,区域合作更加深入,对城市群空间结构提出了更高的要求。本文运用社会网络分析的方法,对长江中游城市群56个城镇空间结构进行实证研究,得出4点结论:①长江中游城市群空间经济联系程度较低,但3个城市子群区域经济联系水平呈现不同,武汉城市圈网络整体密度较高,经济一体化水平较高,长株潭城市群与环鄱阳湖城市群一体化水平处于较低水平;②武汉、长沙、湘潭、株洲、南昌的点出度与点入度较大,与其他城市的通达性良好,经济联系最为紧密;③长江中游城市群城市空间经济联系网络关系存在着不均衡,武汉、长沙、南昌的核心地位最高;④凝聚子群与现有按照行政划分的城市群也基本上是一致的,表现为凝聚子群内城市间经济联系具有很强的相似性。最后提出构建长江中游城市群经济大通道网络体系,加快推进城市群经济空间一体化的发展建议。

Study on the Spatial Structure of Urban Agglomeration in the Middle Reaches of the Yangtze River Based on Social Network Analysis
Abstract:With the enhancement of the comprehensive economic strength of the urban agglomeration in the middle reaches of the Yangtze River, the closer contact with each other in the cities and towns economics, the deeperregional inter-regional cooperation, it is put forward higher requirements for the spatial structure of urban agglomeration. This paper empirical researches the spatial structure of 56 cities and towns in the urban agglomeration in the middle reaches of the Yangtze River, by the use of the social network analysis, draws 4 conclusions: ①Spatial economic relationship level of the urban agglomeration in the middle reaches of the Yangtze River is low, but economic relations of the 3 urban agglomeration subgroups show different levels, Wuhan city circle has higher network density, and higher level of economic integration. The integration level of Changsha-Zhuzhou-Xiangtan urban agglomeration and Poyang Lake urban agglomeration is low; ②Wuhan, Changsha, Xiangtan, Zhuzhou and Nanchang have greater outdegree and indegree, good access and most closely related to the other cities in the region; ③There is an uneven city spatial economic relationship in the urban agglomeration in the middle reaches of the Yangtze River, and The core status of Wuhan, Changsha and Nanchang is the highest; ④The condensed subgroups are basically consistent with the existing urban groups according to the administrative division, which shows a strong similarity between the urban economic connections within the condensed subgroups. Finally, it puts forward a proposal to construct a large economic channel network system of the middle reaches of the middle reaches of the Yangtze River and accelerate the development of the economic spatial integration of the urban agglomeration.
