The changes in demand disruptions and credit prices in the new energy vehicle (NEV) market under the dual credit policy pose challenges to the decision optimization of vehicle manufacturers and battery manufacturers in different production modes. To address this issue, based on the characteristics of the dual credit policy, this paper constructs a Stackelberg game model for both a single production mode that only produces NEV and a hybrid production mode that produces both NEVs and internal combustion engine vehicles (ICEVs), and solve for the optimal battery research and development (R&D) levels and pricing decisions of enterprises. On the basis of indepth analysis of the results, we further validate the results using numerical examples. The research results indicate that both demand disruptions and credit prices have a positive correlation with the sales prices of NEVs, battery prices, and battery R&D levels; Interestingly, demand disruptions and credit prices also have a positive correlation with the sales prices of ICEVs in a hybrid production mode; The decisions and profits of enterprises in a single production mode have higher robustness compared to a hybrid production mode; Government departments should actively continue to implement the dual credit policy and increase the credit price, which not only benefits the development of the NEV industry, but also contributes to the global environmental protection cause. 2020 Mathematics Subject Classification. 91A80.
