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。运用社会网络分析方法,对长江中游城市群56个城镇空间结构进行实证研究,结果表明,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呈现不同水平,武汉城市圈网络整体密度较高,经济一体化水平较高,但长株潭城市群与环鄱阳湖城市群一体化水平较低;2)就点度中心度、紧密中心度和中介中心度来说,武汉、长沙、湘潭、株洲、南昌的点出度和点入度较大,与其他城市的通达性良好,经济联系最紧密;3)在长江中游城市群城市空间经济联系网络关系中存在不均衡,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基本一致,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。

Abstract: With the enhancement of comprehensive economic strength of the urban agglomeration in the middle reaches of the Yangtze river, economic relations of the cities and towns are more closely within the region, regional cooperation is more in-depth, and a higher demand is proposed on the urban agglomeration spatial structure. This paper empirically analyzes 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. The results show that: 1) Spatial economic link degree of the urban agglomeration in the middle reaches of the Yangtze river is low, but regional economic relations of the 3-city subgroup show different levels. Wuhan city circle has higher network density and higher level of economic integration. The integration levels of Changsha-Zhuzhou-Xiangtan urban agglomeration and Poyang lake urban agglomeration are low. 2) As for the degree of centrality, closeness and betweenness, Wuhan, Changsha, Xiangtan, Zhuzhou and Nanchang have greater degree of output and input, and they are closely related to other cities, and have the mostly close economic relationship. 3) In urban agglomeration in the middle reaches of the Yangtze river, spatial economic relations between cities are unbalanced. Wuhan, Changsha and Nanchang in their respective urban agglomerations are at the core. 4) The cohesive subgroup is basically consistent with the existing urban agglomeration in accordance with the administrative division, showing a strong economic tie similarity between the cities in the cohesive subgroup. Finally, this paper puts forward proposals for the construction of economic corridor network system in the middle reaches of the Yangtze river and promoting the development of economic and spatial integration of the urban agglomeration.
Key words: geography; spatial structure; social network analysis; urban agglomeration in the middle reaches of the Yangtze river
