Research on Innovation Mechanism of Industry Cluster Embedded in Social Networks Relation

In this paper, the new economic sociology perspective is applied for in-depth study on industry cluster innovation mechanism. Industry cluster is an economic system, but also a social system. The economic behavior of industrial cluster is embedded in social networks. And the embeddedness of industrial cluster is a fundamental characteristic of social networks. According to the principle of Granovetter's "weak ties", the tie strength of the individual and the extent of the heterogeneity of the located network indirectly affect the validity of the information that the individual in the network obtains. Therefore, the strong ties and weak ties play a unique role in cluster network trade and innovation. A cluster network with integrated structure and thorough function needs to have both of such relation networks and have the ability to maintain the relative balance of them in the dynamic evolution. This relatively balanced cluster network ties strength is the ideal structure of innovation cluster network.
