Research on Output-Input Feedback Mechanism of Regional Innovation System Based on "Four-Three Structure Model"

Based on the Four-Three Structure of regional innovation system,this paper constructs the Output-Input Feedback Model of regional innovation system according to the assumptions for model simplification by using System Dynamics.It analyzes feedback loops of talent,capital and technology,the three major innovation input factors and summarizes key factors which affect the operation of regional innovation system,so as to provide a theoretical basis for regional innovation strategy implementation.
