This article will complex network theory is introduced to the world's leading technology innovation cooperation network study, continue to deepen the theoretical study, by numerical simulation and empirical research on the method of combining technical innovation cooperation network to the evolution mechanism and its small world, scale-free characteristics were studied. First perfect the network modeling work decline period. Secondly, put forward the strategy of technology innovation diffusion, namely random selection, target selection and associated enterprises selection strategy, and compares the advantages and disadvantages of relationship between different strategies. Finally, combined the status quo of the cooperation technological innovation in our country, respectively from two levels to enterprises and government strengthen enterprise technical cooperation and improve enterprise technology innovation ability, and puts forward some Suggestions and countermeasures of technology innovation cooperation network further study is forecasted.
