Interactive Rules on Supply and Demand Actions of Knowledge Supply Chain

Few studies have paid any attention to the analysis of interaction between the subjects of knowledge supply chain, this paper studied subjects, characteristics, conceptual model of knowledge supply chain from the angle of supply chain management. Industry, university and government are considered to be subsystems of the main social system, and innovative achievements, enterprises profit and policies supporting intensity had been viewed as level variables of these three subsystems. System dynamics model of knowledge supply chain had been constructed using the method of simplified rate variable fundamental In-tree model. The problems of knowledge transmission, interaction and innovation mechanism between subsystems had been researched into, and the fields that the results in this research could be applied to had been summarized finally.
