Abstract
Electric vehicles (EVs) are regarded as an effective method for dealing with serious environmental pollution. The Chinese government has implemented a series of incentives to accelerate the promotion of EV. However, the increasing production of EVs gives rise to a greater demand for better quality charging station. This study aimed to certify the impact of the production of EVs on charging station research and development (R&D) in China, with mediating effect methods and a panel fixed effect model. The conclusions derived from the study were: (1) Statistically, the production of EVs positively and significantly impacts charging station R&D; (2) the mediating role of investment in charging stations is verified in the relationship between the production of EVs and charging station R&D; (3) environmental tax can moderate the relationship between the production of EVs and charging station R&D. These results implicate, for the first time, that the production of EVs can enhance charging station R&D through the mediating role of charging station investments and the moderating role of environmental tax.

We suggest that environment tax can moderate the path from EV production to charging station research and development (R&D)
We found that the impact of production of EVs on charging station R&D is more notable in regions of higher rather than lower environmental tax, which indicates that increasing environmental tax effectively promotes the positive impact of the production of EVs on charging station R&D
Summary
Processes 2021, 9, 1407. https://Nowadays, the electric vehicle (EV) industry is emerging with great significance in both economic growth and environment protection [1,2]. The development of EVs correlates with the ecological goal of carbon peak and carbon neutral [3,4]. Under the policy encouragement of governments and international communities, the popularization of EVs has been increasing rapidly year by year [5,6,7]. The fast-growing production of EVs puts a higher demand on improving the quantity and quality of charging stations [8]. Governments have started promoting the innovation and application of charging stations through more investment [9,10] and incentive policies [11,12]. The optimization of charging services infrastructure will further benefit the development of the low-carbon economy [13,14]
