政府补贴下绿色供应链的竞争与合作研究OA

Against the backdrop of continuously increasing global carbon emissions and complex game relationships among various participants in the green supply chain,it is particularly crucial to study how to achieve a win-win situation for economic and environmental benefits in the competitive and cooperative landscape of green supply chains.Taking new energy vehicles as an exam-ple,this paper constructs three supply chain models consisting of suppliers,manufacturers and consumers with government subsi-dies and based on the non-cooperative-cooperative game theory,adopts the Stackelberg equilibrium and Shapley's value theory to reveal the relationship between the green supply chain and the green supply chain.theory,the interaction mechanism of price com-petition and technology synergy among green supply chains is revealed.It is found that R&D subsidies and production subsidies pro-vided by the government have obvious differentiated impacts on the pricing decision and profit distribution of the supply chain:al-though R&D subsidies can effectively enhance the level of green technological innovation,there is a diminishing marginal benefit effect of over-subsidization;whereas production subsidies can stably promote the continuous expansion of market demand and in-crease the overall profit of the supply chain,so the government should set the subsidy intensity according to the stage of the supply chain's development.Therefore,the government should set the subsidy intensity reasonably according to the development stage of the supply chain.
