针对供需网企业间合作创新行为稳定性问题，基于知识溢出这一视角，选择供需网企业之间的合作创新行为为研究对象，在有限理性前提下，运用演化博弈理论，构建了供需网企业合作创新行为演化博弈模型，在此基础上，探讨了供需网企业合作创新行为路径演化轨迹，最后利用数值仿真方法研究了影响博弈系统合作稳定性的因素。研究发现：供需网企业合作创新行为的演化与其初始构建的支付矩阵密切相关，也与支付矩阵的初始参数选择有关；知识投入，知识互补程度，以及知识溢出系数是影响企业合作演化的重要因素，其中，增大知识投入，增大知识互补程度以及知识溢出系数将会有效的促使供需网企业合作创新行为朝着合作的方向演化。

In order to explore the problem of the stability of cooperative innovation in Supply and Demand Network from the perspective of knowledge spillover, this paper chosen the cooperative innovation behavior of Supply and Demand Network as the research object, and used the evolutionary game theory to construct the evolutionary game model of cooperative innovation behavior of the supply and demand network under the premise of bounded rationality firstly. Secondly, it discussed the path of evolution of the cooperative innovation behavior of supply and demand network, and used the numerical simulation method to study the factors that affect the stability of game system cooperation, finally. It is found that the evolution of cooperative innovation behavior of supply and demand enterprises is closely related to the initial payment matrix, and it is also related to the initial parameter selection of payment matrix; Knowledge input, knowledge complementarity and knowledge spillover coefficient are important factors that influences enterprise cooperative evolution. Increasing the knowledge input，the degree of knowledge complementarity and knowledge spillover coefficient can be effective to promote the cooperation of enterprise of Supply and Demand Network.
