RESEARCH ON NETWORK EQUILIBRIUM OF AGRICULTURAL SUPPLY CHAIN BASED ON GOVERNMENT SUBSIDIES AND GREEN INVESTMENT

In this paper, we employ variational inequality theory to formulate a finite-dimensional model of the agricultural product supply chain, encompassing the decision-making roles of agricultural production bases, businesses, retailers, and demand markets. Furthermore, we explain the model from an economic perspective. Finally, using numerical simulation, the implications of government subsidies, green input levels of agricultural production bases, and enterprise testing technology input levels on market demand and the profits of every link in the supply chain are explored. The findings of the study demonstrate that: increasing green investment of agricultural production bases, businesses, and government subsidies can not only boost individual supply chain member profits but also increase the market demand and enhance overall sales volume. Contrarily, incorporating green business investments, agricultural production bases, and government subsidies simultaneously can increase the supply chain's overall profit.
