At present, the biomass energy resource utilization projects carried out in many regions have suffered losses to varying degrees. The reason is that the supply of biomass energy raw materials is insufficient. The basis for this situation lies in the participation of farmers, biomass energy The degree of cooperation between enterprises and farmers and the implementation of policies by local governments. As a big agricultural country, my country is rich in raw material resources of agricultural biomass energy, which is economical and convenient, and has now become the main raw material of biomass energy. This paper takes agricultural biomass energy as the research direction, from the perspective of behavioral heterogeneity, considers the stakeholders involved in the development of agricultural biomass energy, and establishes the evolution of three biomass energy resource-based stakeholders: farmers, biomass energy companies and local governments. The game model explores the game behavior of different subjects in the process of biomass energy resource utilization, and simulates the changes in environmental protection subsidies through system dynamics simulation software, and makes decisions about biomass energy-related policies according to the simulation results. and provide a reference basis for improvement.
