【摘要】：基于修正的引力模型,建立了成渝经济圈城市群的经济联系网络结构模型。借助社会网络分析方法,实证分析了成渝经济圈城市群经济联系网络的联系强度、网络密度、网络中心性以及凝聚子群。结果显示:成渝经济圈城市群整体的网络密度处于中高水平,城市群已形成实际意义上的经济网络,城市间的经济联系密切但具有明显的不均衡性;城市群基本形成了以成都和重庆为核心驱动周边城市网络化协同发展的格局,但城市群内的枢纽型城市较少;集群内存在明显的小团体现象,凝聚子群间经济联系的广度和深度有待加强。
[Abstract]:Based on the modified gravity model, the economic connection network model of Chengdu-Chongqing economic circle urban agglomeration is established. With the help of the social network analysis method, the paper empirically analyzes the connection intensity, network density, network centrality and condensed subgroup of the economic connection network of Chengdu-Chongqing economic circle urban agglomeration. The results show that the overall network density of Chengdu-Chongqing economic circle urban agglomeration is in the middle and high level, the urban agglomeration has formed the economic network in the actual sense, the economic relation among cities is close but has obvious imbalance; The urban agglomeration has basically formed the pattern that the core is Chengdu and Chongqing, but there are few hub cities in the urban agglomeration, and there is obvious small group phenomenon in the cluster. The breadth and depth of economic links between condensed subgroups need to be strengthened.
