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
