Research on the Interaction Coupling between Disruptive Innovation and Knowledge Spillover

Disruptive innovation is the main form of innovation for latecomers to catch up with technology. Knowledge spillover can achieve low-cost disruptive innovation, which has an important impact on the development of disruptive innovation. Disruptive innovation of latecomers can promote the flow of knowledge in the production network. Disruptive innovation and knowledge spillover are two independent and interrelated systems, but the relationship between them is not fully explained. In this paper, the index system of interactive coupling evaluation is constructed, the index weight is calculated by entropy weight method, and the coupling evaluation model of disruptive innovation and knowledge spillover is established to reveal the relationship between them. It is found that disruptive innovation and knowledge spillover are in the stage of moderate coupling and highly coordinated coupling and the contribution rate of the two systems in the total system will affect the coupling and coordination between them.
