Abstract:

The lack of charging infrastructure has significantly hindered the widespread promotion of new energy vehicles in China. Establishing partnerships between the public sector (government) and the private sector (enterprises) is one important approach to address this issue. In this study, a tripartite game model involving the government, enterprises, and consumers was constructed to examine the effects and differences in investment in electric vehicle charging infrastructure under three types of government- enterprise cooperation models: government-funded, feasibility gap subsidy, and user-funded. Based on this, the optimal investment model for new energy vehicle charging infrastructure is discussed. The research findings indicate that (1) government and enterprise cooperation can enhance investment in new energy vehicle charging infrastructure and promote the large-scale adoption of new energy vehicles. (2) Compared to government-funded and user-funded models, the feasibility gap subsidy model not only has a positive impact on promoting electric vehicles but also enhances social welfare, making it the optimal investment model for new energy vehicle charging infrastructure. (3) Under the feasibility gap subsidy model, the optimal subsidy ratio for the construction and operation of charging infrastructure gradually decreases as the cost coefficient increases, while the optimal charging service fee price level gradually increases. The conclusions of this study are of great significance for the widespread promotion of new energy vehicles in China and the attainment of the transportation sector’s “dual-carbon” goals.
