The Research Of High-tech Industry Evolution Mechanism Cluster Based On Network Theory

At present, research of industry cluster was concentrated on the classic industry clusters, and much of them studied them from the macroscopic economic domain. The papers, adopted the network and the value chain theory, systematically analyses and studies the high-tech industry clusters from the microscopic domain firstly; and defines high-tech's concept, network, and network joint, network interface and so on, then pointes out it is helpful to reduce the transaction cost and the management cost under network equilibrium, which is advantageous to promote the high-tech cluster's competition, derivation and withdrawal. The papers analyzes network equilibrium and balance condition from establishing mathematical model, based on this, the papers summarizes and analyzes the evaluation way and the mechanism of the high-tech industry clusters, as well as the value chain extension of the high-tech industry cluster in the evolution process, then analyzes its evolution mechanism from establishing the model of the evolution way.Research on character of high-tech industry cluster shows that enterprises in cluster spin-off through innovation and give birth to the new value activity under the market pressure, in the relations of high-tech industry cluster's network, at the same time the network of industrial chain value shifts from the dominance to the recessive activity. Along with industrial value chain extending, cluster network density and network latitude also change, and in order to provide the convenience of communication, network interface also becomes better and better, which not only develops vertical network, but also breeds auxiliary network and horizontal network. Finally, the high-tech industry cluster achieves balance. The balanced and perfect network creates the good environment for cluster innovation and service, thus the high-tech industry cluster has obtained the power to develop continuously. At the same time, the balanced network also reduces the transaction cost of high-tech industry cluster network joint and the control cost, which enhances the whole competitive ability of the cluster. The analysis of the papers is based on the performance of Chinese high-tech industry clusters; therefore the analysis and the conclusion are significant for comprehension of the high-tech clusters, the innovation of management and the choice of policy.
