Crop straw has the characteristics of natural carbon neutrality and stable output guarantee,which provides an effective way to deal with the current climate change and energy crisis.However,in actual production,the amount of straw that can be used for power generation accounts for a relatively low proportion,and the shortage of raw material supply leads to the loss or even production suspension of most power plants.The reason lies in the lack of supply chain management and coordination,the goal of participants to maximize their own revenue,the inefficiency of independent decision-making and the conflict of interests among members,resulting in the failure to achieve the optimal balanced decision-making.With the launch of the national carbon market,straw power generation enterprises can gain profits by selling Chinese Certified Emission Reduction(CCER),which to some extent makes up for the negative impact caused by the decline of state subsidies.In view of the reality of both opportunities and challenges,how to guarantee the supply of straw fuel and how to reasonably distribute the supply chain revenue have become the key to the smooth operation of the industry.This paper takes the straw direct combustion power supply chain composed of farmers,brokers and power plants as the research object,aiming to explore the decision-making strategy and revenue distribution of supply chain under the current policy and market background.Firstly,the economic cost of straw direct combustion power supply chain is considered,including collection,transportation,storage and power generation stages.Then,combined with the carbon emission of coal-fired power plants and straw power plants in the whole life cycle,taken into account the market carbon price.The Stackelberg master-slave game model under decentralized decision-making mode,and the supply chain overall revenue model under centralized decision-making mode are constructed.By comparing and analyzing the optimal solution of the model,it was found that straw amount increased significantly and total revenue increased under the centralized decision-making condition.Then,based on the supply quantity in centralized decision making,the Revenue Sharing Contract(RSC)is used to coordinate,and the total revenue in centralized decision making is redistributed through the combination design of contract parameters and purchase price.Finally,the feasibility and validity of the model are verified by numerical calculation,and the sensitivity of some parameters is analyzed.The results show that the RSC not only brings more straw raw materials to the power plant and improves the total revenue of the supply chain,but also the reasonable combination of straw purchase price and revenue sharing coefficient can Pareto improve the income of all participating members in the supply chain and achieve a win-win situation.From the perspective of supply chain benefit coordination,this study quantitatively analyzes the environmental benefits brought by direct burning of straw for power generation.The research results can further guarantee the continuous and stable supply of fuel for power plants,help the members of the supply chain to maximize the benefits,and provide relevant decision-making reference for policy makers,so as to promote the sustainable development of the direct burning of straw for power generation industry. |
