Research on Eco-Product Supply Chain Decision-Making and Coordination Under Different Subsidy Strategies with Ecological Cost-Sharing Contracts

In order to solve the problem of poor market circulation in the process of realizing the value of ecological products, this paper studies a supply chain system composed of a single ecological product supplier, an ecological product distributor, and a consumer. Since government subsidies will greatly affect the operation of the supply chain system, the supply chain decision-making model under three scenarios, of no government subsidies, development and operation subsidies, and consumer subsidies, is constructed with an ecological cost-sharing contract coefficient between suppliers and dealers. Then, the Stackelberg game is used to solve the optimal strategy and maximum profit of all parties in the supply chain under different financial subsidy scenarios in order to form eco-product development suggestions in line with market rules.
