摘要： 长江中游城市集群发展对统筹区域协调发展和促进中部崛起具有战略意义,分析长江中游城市集群经济网络结构有助于城市和区域发展战略的制定。本文在改进引力模型的基础上,借助社会网络分析方法(SNA),构建以经济联系强度和经济网络结构特性为核心的城市集群经济网络结构模型,实证分析了长江中游城市集群经济网络的网络密度、网络中心性和凝聚子群,以揭示其经济网络结构特征。研究结果显示:长江中游城市集群整体网络密度处于中高水平,已经形成实际意义上的经济网络;集群内小团体现象明显,一级层面形成了4 个凝聚子群,武汉都市圈和湖南环长株潭城市集群两子群内经济联动作用明显,但子群间经济影响较小,尤其是环鄱阳湖生态经济区内的两个凝聚子群,其联系纽带尚有待加强;集群内以武汉、长沙、南昌为主的中心城市驱动周边城市联动发展的格局基本形成,辐射带动作用明显,但吸收能力欠缺。

Abstract: The development of urban agglomerations in the middle Changjiang River is strategically significant for integrating coordinated development and enhancing the rise of Central China, so the research of related economic network structure is beneficial for the making up of urban and regional development strategy. Based on modified gravitation model and using social network analysis, this paper constructs an urban agglomeration economic network structure model which takes economic ties strength and economic network structural statistical features as the core. Then, this paper empirically studies the urban agglomeration economic network of the middle Changjiang River. The results are shown as follows. (1) The whole network density is staying at middle-high level and the economic network scale has formed. (2) The network has many subgroups, and in the internal of subgroups of Wuhan Metropolitan Circle and Hunan "3 + 5" urban agglomeration, the economic interaction is obvious, while the interaction between these two subgroups is not significant; especially in the ecological economic zone of Poyang Lake region, an internal tie needs to be strengthened. (3) The pattern that central cities such as Wuhan, Changsha and Nanchang take the lead in the development of this urban agglomeration has formed, and their radiation effects are obvious, while the absorbing abilities are insufficient.

Key words: social network analysis, urban agglomeration in the middle Yangtze River, economic network, gravitation model
