The Revision of the process and model of technology diffusion

Technology diffusion is an important measure for promoting industrial upgrading,improving economy and optimizing allocation of resources,which has been studied by many scholars. This paper reviews the relative studies about the process of technology diffusion,analyzes the relations between the diffusion process and network structure and the influencing factors in the diffusion process; summarizes the mechanism of technology diffusion,which puts attention on dynamic mechanism and motivation mechanism; makes a systematic analysis to the diffusion models from three aspects including macro diffusion model,micro diffusion model and based on the complex network diffusion model. And then,the current research status of technology diffusion is reviewed and the future research direction is discussed.
