Research on Game Model of Technical Innovation Diffusion

The value of innovation lies in it´s diffusion, but the process of diffusion on network depend on the topological structure and rules of diffusion. The affections of complex topology of industrial network on the diffusion of technical innovation are studied. At the same time, the diffusing rules of technical innovation are analyzed based on game theory in the paper. Some conclusions are made out: the scale-free character of industrial network affects the threshold of diffusion; the small-world character affects the speed of diffusion; the Nash equilibrium shows that the diffusing probability of disseminator is proportional to the difference of studying cost and rejecting cost of studier, the studying probability of studier is not only proportional to the quarantine cost of disseminator, but also to the average degree of network. At last, the average steps of technical innovation diffusion on industrial network are showed based on the absorbing status of Markov chain.
