Focusing on the selection of knowledge sharing strategy when community members participate in the de? velopment of intangible cultural heritage tourism, this paper constructs the evolutionary game model of commu? nity members participating in the development of intangible cultural heritage tourism, solves the evolutionary sta? bility strategy of community members, and analyzes the evolutionary process of each parameter of the model on the strategy selection of community members with the help of MATLAB software. The results show that knowl? edge stock, trust coefficient, complementary coefficient, collaborative innovation benefit, reward coefficient and speculative punishment value have a positive impact on community members’participation, while sharing cost and risk coefficient have a negative impact on community members’participation. Properly setting the benefit distribu? tion coefficient of collaborative innovation will promote the knowledge sharing behavior of community members.
