Evolution path of synergetic innovation networks of SMEs in cluster

The synergetic innovative networks of small and medium enterprises (SMEs) in cluster play a great role in the innovative growth of enterprises and industrial cluster development. The evolution of the synergetic innovative networks of SMEs in cluster is a replicated dynamic process of subjects in cluster decision-making. The cluster strategy choice, formed by subjects in cluster imitating other subjects in making strategy choices, determines the evolution of the synergetic innovative networks. Introducing the duplicated dynamics model in evolutionary game theory into this issue, the paper worked out the equilibrium points of both parties in the network relationship. Analysis of further equilibrium points indicates that under different conditions, the synergetic innovative networks of SMEs in cluster form three paths, namely a benign, single declining and full declining ones.
