Through evolving of industrial clusters, applying a new evolving network model based on small worlds network model and individual selection model, this paper studies the characteristics and process of clustering network evolving. The model can simulate the process from forming period to mature period of a industrial clusters networks, and its intensiveness, connectedness and centrality. It also explains and analyzes the forming mechanism of the industrial clusters. The results show that small world network model could explain the big change of intensiveness and connectedness in forming process. And individual selection value function could explain the stable intensiveness, connectedness in growing and mature process. Combined the both, the characteristics of the whole process could be reflected. Finally, it provides the inside factors and policy revelation of industrial cluster networks evolution from small world and value function mechanism.
