Abstract:The structure of the cultural industry cluster determines the degree of cluster development, the direction and depth of the evolution of the cluster. The paper builds the four index, including network density, agglomeration coefficient, network centrality and average shortest path length, based on Changzhou national animation industry cluster using the social network analysis (SNA). The study results shows the network density and agglomeration coefficient of Changzhou national animation industry cluster is slower and weaker link state, cluster global network centrality is not high, average shortest path length is shorter, which indicates that cluster network subject is not perfect, connection is not close enough and cluster network resources are not enough. Therefore, the improvement of the structure of the Changzhou national animation industry cluster should improve the main elements of the structure, enhance the innovation cohesion of the structure, stimulate the innovation of the structure and optimize the innovation environment of the structure and so on.
