Abstract: As to the supply of raw materials in the straw power generation, this paper deals with the modeling and analysis on the straw power generation supply chain under the government incentives from the perspective of evolutionary game perspective in the first time. First, the influencing factors of straw power generation supply chain are analyzed, and based on the sequential decision-making model of the straw power generation supply chain which is composed of power plant, brokers and farmers, the optimal decision-makings of three participants are obtained. Second, the decision-making and profit change of the supply chain under the government incentives is analyzed, and the importance of the government incentives is approved. Then, under the government incentives, the evolutionary game model between power plant and brokers is established and the incentive strategies are obtained. Finally, an example is taken to explain the cooperation relationship between the power plant and brokers in the straw power generation supply chain, which also verifies the proposed models and analysis. This study disclosed cooperation rules in the straw power generation supply chain, and provided the basis for enterprise decision making of power plants and brokers, as well as government regulation, so as to establish long-term cooperative relationship to promote the development of straw power generation industry.

Key words: evolutionary game, straw power generation, supply chain, government incentive
