Game Analysis for the Industrial Technological Innovation Decision Based on the Knowledge Spillover in Industrial Clusters

In the abundant information and knowledge era, technological innovation gives core competition power among enterprises. Knowledge spillover has changed the cluster´s knowledge environment for technology innovation, and also the profit distribution of cluster´s enterprises, which affects the innovation initiative and decision of enterprises. Using evolutionary game theory model to analyze the industrial innovation decision impacted by different knowledge environments, we can get the conclusion: Knowledge protection and enterprise self-control are necessary condition for industrial continuous growth. The purples of knowledge protection is not to tame the spillover but to protect the innovation initiative.
