Abstract:The high-tech industry cluster has the characteristic of knowledge intensive, and the research on the mechanism of its innovation and diffusion is of great significance to the formulation of the innovation policy and the industry development strategy. Through potential imitators based on individual utility decision-making behavior, the conditions of innovation diffusion are set as the basic power of self-organization network and constituting the network boundaries of Zhongguancun Industrial Park as a high-tech industry cluster. On this basis, this paper studies the characteristics of cluster innovation diffusion network, such as topology form of innovation diffusion, diffusion of innovation strength and density and other related indicators, which will provide the reference and theoretical basis for high-tech industry cluster innovation diffusion research.
