Research on Decision-Making Optimization of New Energy Vehicle Supply Chain Considering Stigma Level

In recent years, despite the rapid development of the new energy vehicle (NEV) industry, the continuous emergence of stigmatization incidents around car battery life has also brought challenges to corporate decision-making optimization. In order to solve this problem, we construct a model for the supply chain structure composed of NEV manufacturers and battery manufacturers under the two situations of information disclosure or no information disclosure, and then solves the model based on Stackelberg game theory. In order to further analyze the results, we also use numerical examples to verify the model results. The results show that the stigma level negatively affects the optimal pricing and profits of enterprises; If the information disclosure decision-making is taken, it is conducive to reducing the profit loss of NEV manufacturers and battery manufacturers; Interestingly, the information disclosure decision-making adopted by NEV manufacturers is more conducive to reducing the profit loss of battery manufacturers than it is for itself.
