Abstract:

Currently, the recycling and reuse of waste products in the manufacturing industry has gradually scaled, while the recycling and reuse of crop straws are lagging behind. Straw mulching can realize the reuse of straw resources, solve the environmental pollution caused by straw burning, and reduce the application of chemical fertilizers for agricultural products. To realize the sustainable development of agriculture, governments has formulated some straw recycling subsidy mechanisms to promote straw reuse. However, as an important carrier of agricultural product planting and straw returning, sustainable agricultural product supply chain network system should not only consider the sustainability of the system economy, but also consider the recycling of resources, and also consider improving the greenness of agricultural products to increase social welfare. Therefore, it is necessary to study the equilibrium of sustainable agricultural product supply chain network under different straw recycling subsidy mechanisms, and to explore the optimal straw recycling subsidy system, which is important theoretical and practical significance.In this paper, the equilibrium problem of a sustainable agricultural product supply chain network is explored, which includes farmer cooperatives, retailers, and demand markets. Under the assumption of straw recycling and mulching of farmer cooperatives, the equilibrium model of the whole system considering three recycling subsidy mechanisms including unit recycling subsidy mechanism, regulated recycling subsidy mechanism and progressive recycling subsidy mechanism is established. Then, numerical examples are used to verify and analyze the model. The results show that no matter what recycling subsidy mechanism is taken by the government, the increase in the recycling subsidy level is conducive to improving the trading volume of agricultural products, increasing the efficiency of recycling and mulching of straw, and also conducive to improving the profits of the members and the whole system. Through the comparison of the three subsidy mechanisms, it is concluded that with the increase in the level of recycling subsidies, the progressive recycling subsidy mechanism is more conducive to promoting recycling and mulching of straw, and increasing the profits of retailers. The unit recycling subsidy mechanism is more conducive to the profits of the farmer cooperatives and the whole system, and the progressive recycling subsidy mechanism is second. Particularly, from the perspective of the overall economic, environmentally, and social sustainable development of the system, the progressive recycling subsidy mechanism is better.Finally, according to the research conclusions, some management suggestions are given from the perspective of government and members, which can provide theoretical and practical suggestions for the formulation of government mechanisms and agricultural-related enterprises decisions.
