The Utility Optimization of Science & Technology Information in the Context of Knowledge Supply Chain

On the basis of the characteristics of knowledge supply chain (KSC) operation, this paper analyzed the circulation process of knowledge connoted, and constructed a description structural model of KSC on the basis of knowledge value realization. from the aspects of knowledge diffusion, information increment and knowledge innovation, explored the optimization process of the flow, transmission, diffusion, and utility optimization of science & technology (S&T) information in the context of KSC.
