How Do Government Subsidies and Consumer Preferences Promote New Energy Vehicle Diffusion? A Study Based on Evolutionary Equilibrium Strategy Method

The diffusion of new energy vehicles（NEVs）accounts for only a small part of the current car market. How to effectively guide energy vehicle manufacturers to produce NEVs and promote consumers’ purchasing behavior has become an urgent issue need to be addressed. From the perspective of supply chain, this paper establishes an evolutionary game model involving the energy vehicle manufacturer, the consumer and the government, and analyzes the evolutionary stability conditions and evolutionary stability strategies of all parties. MATLAB2019b application program is used to simulate and analyze the data obtained by method of simulated moments. The results show that: (1)Both the energy vehicle manufacturer and the consumer are influenced by the decisions of the other two game players, while the strategic choices of the government are only influenced by the consumers’ strategic choices. (2)Appropriate government subsidies, reducing the sales price and production cost of NEVs, improving consumer preferences for NEVs and improving the environmental friendliness of NEVs are conducive to the diffusion of NEVs. (3)Compared with other factors, improving consumer preferences and improving the environmental friendliness of NEVs are the most beneficial ways to promote the diffusion of NEVs. Finally, some policy implications are put forward
