生态耦合下高技术产业集群横向创新链主体合作策略演化研究

Research on the Evolution of Cooperation Strategies of Subjects in the Horizontal Innovation Chain of High-Tech Industry Clusters under Ecological Coupling

摘要:

高技术产业集群创新链主体集聚与互动耦合是集群创新能力形成与演化的内在基础。本文从知识生态耦合视角对集群横向创新链主体合作策略演化展开研究,构建集群横向创新链主体和其邻居合作交互的演化博弈模型,进行系统稳定性分析,并考虑到网络嵌入性,对不同网络规模下的集群横向创新链主体合作策略进行动态演化仿真分析。研究发现:知识互补度能促进集群横向创新链主体间合作策略演化,并且该促进作用存在一个临界值,随着网络规模的增大临界值从0.5上升至0.8,但是网络规模越大网络演化的速度越慢。另外,知识重叠度对集群横向创新链主体间合作策略演化起抑制作用,不过存在一个较低的临界值0.4,当知识重叠度低于临界值时能够促进集群横向创新链主体合作；超过临界值后随知识重叠度的增加,对集群横向创新链主体合作的抑制作用增大,而且知识重叠度产生的作用不受网络规模的影响。研究结论可以为集群横向创新链主体合作策略的制定以及政府对产业集群的布局提供一定依据。

Abstract:

The agglomeration and interactive coupling of subjects in the innovation chain of high-tech industrial clusters are the intrinsic foundation for the formation and evolution of cluster innovation capability. In this paper, from the perspective of knowledge ecological coupling, we study the evolution of cooperation strategies among the main bodies of horizontal innovation chain of clusters, construct the evolution game model of cooperation and interaction between the main bodies of horizontal innovation chain of clusters and their neighbours, carry out the stability analysis of the system, and take into account the embeddedness of the network, and carry out the simulation analysis of the dynamic evolution of the cooperation strategies among the main bodies of horizontal innovation chain of clusters with different network sizes. It is found that the degree of knowledge complementarity can promote the evolution of cooperation strategies among subjects of cluster horizontal innovation chain, and there exists a critical value for this promotion, which rises from 0.5 to 0.8 with the increase of network size, but the larger the network size, the slower the speed of network evolution. In addition, the degree of knowledge overlap has an inhibiting effect on the evolution of cooperation strategies between subjects in the horizontal innovation chain of clusters, 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 between subjects in the horizontal innovation chain of clusters; with the increase of the degree of knowledge overlap, the inhibiting effect on the cooperation between subjects in the horizontal innovation chain of clusters increases when the value of knowledge overlap is exceeded, and the effect of the degree of knowledge overlap is not influenced by the size of the network. The effect of knowledge overlap is not affected by the network size. The findings of the study can provide some basis for the formulation of cooperation strategies of horizontal innovation chain in clusters and the layout of industrial clusters by the government.
