Abstract
The development of public charging infrastructure has become an important component of smart city construction and energy conservation and emission reduction. As the country with the largest number of electric vehicles in the world, China's experience in the development of public charging infrastructure is of demonstrative significance globally. This article constructs a comprehensive evaluation index of the development level of public charging infrastructure based on provincial panel data from 2018 to 2023 and measures it using the entropy weight-TOPSIS method. By analyzing the coupling coordination degree between the development level of public charging infrastructure and regional resilience, spatial and temporal differences and evolutionary characteristics are explored. Finally, the factors influencing the development are analyzed using a spatial Durbin model with mixed fixed effects. The results show that: 1) The development level of public charging infrastructure in China has been increasing year by year, but regional disparities are gradually widening, with an increasing probability of downward transfer of coupling coordination status; 2) The coupling coordination degree in most regions of China has reached a primary coordination level or above, and there is a significant spatial agglomeration relationship, with high-value agglomeration areas in the eastern region showing a significant spillover effect in the east-west direction; 3) The development level of public charging infrastructure is influenced by various factors, among which economic development level, power supply capacity, government budget expenditure, urbanization process, pollutant emissions, and environmental temperature are key driving factors. This study analyzes the spatial and temporal pattern evolution of public charging infrastructure in China and its influencing factors, providing decision-making references for the development of global electrified transportation.
