Abstract: Both the preference attachment and regional connection preference were considered in the process of network dynamic evolution. The evolution equation of network degree distribution was derived on the basis of the incremental equation method, which was used in the research of complex networks. The analysis results demonstrated that the innovation network degree distribution followed the power-law. The resource differences among the enterprises are getting larger and larger with the dynamic evolution of network, it brings more technology opportunities for enterprises and is propitious to the production and communication of new technologies. The more uniform the network embedment, the more advantageous to improve the innovation performances of the cluster. Innovation cooperation should be encouraged to optimize the network structure and to reduce the resource monopolization possibilities by few enterprises.
