Research on the Evolution of Cooperation Strategies Among the Subjects of the Horizontal Innovation Chain of High-Tech Industrial Clusters Under Ecological Coupling
The agglomeration and interactive coupling of subjects in the innovation chain of high-tech industrial clusters are the intrinsic basis for the formation and evolution of cluster innovation capabilities.This paper studies the evolution of cooperation strategies of cluster horizontal innovation chain subjects from the perspective of knowledge ecological coupling,constructs an evolutionary game model of cooperation and interaction between cluster horizontal innovation chain subjects and their neighbors,and conducts system stability analysis.Taking into account network embeddedness,a dynamic evolution simulation analysis is conducted on the main cooperation strategies of cluster horizontal innovation chains under different network scales.The study found that the degree of knowledge complementarity can promote the evolution of cooperation strategies among the subjects of the cluster's horizontal innovation chain,and there is a critical value for this promotion effect.As the network size increases,the critical value increases from 0.5 to 0.8,but the larger the network size,the slower the network evolution speed.In addition,the degree of knowledge overlap inhibits the evolution of cooperation strategies among the subjects of the cluster horizontal innovation chain,but there is a lower critical value of 0.4.When the degree of knowledge overlap is lower than the critical value,it can promote the cooperation of the subjects of the cluster horizontal innovation chain.After exceeding the critical value,as the degree of knowledge overlap increases,the inhibitory effect on the cooperation of the subjects of the cluster's horizontal innovation chain increases,and the effect of knowledge overlap is not affected by the network size.
