Research on the profit change of new energy vehicle closed-loop supply chain members based on government subsidies

Based on the research background of government-subsidized new energy vehicle market, this paper constructs a profit distribution model of closed-loop supply chain members without financial subsidies and with different objects of government subsidies. Using the idea and method of game theory, the profit distribution of five models of supply chain members is solved respectively, and the sales channel pricing, recovery channel pricing, change the range of profit of each supply chain member and change of profit distribution proportion of closed-loop supply chain under different subsidy objects are compared. Therefore, it studies how the profit is transferred and analyzes the influence of different government subsidies on the competitiveness of the supply chain.
