Abstract：

Driven by the Dual Carbon goals, China’s automotive industry is accelerating its transition to new energy. Ecological pressures from vehicle emissions and the demand for industrial upgrading make New Energy Vehicles (NEVs) an inevitable choice. To study the factors influencing NEV sales, this paper examines economic factors, infrastructure, market foundations, and administrative factors. Based on annual data of NEV sales from 31 provinces in China from 2016 to 2023, including the number of charging piles, urban disposable income per capita, and civilian vehicle ownership, a dummy variable for national policy subsidies is introduced. The study also explores whether the number of municipal districts (provincial-level cities, autonomous regions, municipalities) indirectly affects NEV sales. A mixed panel dataset is constructed, with data cleaning and visualization performed using R language. Econometric methods are employed for analysis, alongside empirical analysis using Eviews13 and Stata 18.
