摘要：This paper studies the impact of the decrease in government subsidies on the selection of the cooperation model of vehicle manufacturers’ in the new energy vehicle supply chain, and uses the mathematical modeling method to establish MA (cooperation between vehicle manufacturers and battery suppliers with better battery life), MB (cooperation between vehicle manufacturers and battery suppliers with similar battery life) MAB (vehicle manufacturer cooperates with both) and N (does not cooperate with both) four cooperation models. The results show that vehicle manufacturers and battery suppliers A and B have cooperation motives, but whether vehicle manufacturers prefer to cooperate with battery supplier A or battery supplier B is related to the decrease in subsidies. In addition, it studies the impact of the decrease in subsidies on the sales price, market demand and supply chain profit of new energy vehicles.
