In view of a clarification of the strategy choice of inheritors and environmentalists in the sustainable development of intangible cultural heritage in Huizhou, an evolutionary game model of inheritors and environmentalists has thus been constructed, with the local equilibrium point of the evolutionary game model solved by copying the dynamic equation, followed by an analysis of the stability of the equilibrium point. Finally, the evolutionary path of interaction between environmentalists and inheritors is to be simulated by using the simulation software. The results show that the strategic choice of the two in the process of game can be directly determined by the hidden value of intangible cultural heritage resources in Huizhou and the initial cost paid by the environmentalists. Meanwhile, the distribution coefficient of excess income and the punishment coefficient of environmentalists also exert an influence on the direction of the final evolution of the system to a certain extent.
