What drives electric vehicle adoption? Perspectives from a geospatial and longitudinal study
利用充电站和电动汽车销售的地理编码数据，通过工具变量法解决内生性问题，发现高效便捷的充电站是影响电动汽车普及的关键因素，且该效应在控制社会经济因素后依然显著。
Electric vehicles represent an innovative solution with the potential to reduce emissions contributing to climate change. However, the global EV market is reaching a critical point in its life cycle, where adoption rates are lower than projected, necessitating an understanding of the key factors affecting EV adoption decisions among the next generation of consumers. In this article, we use a novel geocoded dataset of charging stations and EV sales to investigate how charging infrastructure shapes EV adoption over time in areas with diverse demographics. Employing an instrumental variable approach to address potential endogeneity and fixed effects models to account for unobserved heterogeneity across regions and time periods, we identify evidence supporting the critical role of efficient and accessible charging stations. After controlling for a wide range of socio-economic factors and commute behaviours, charging infrastructure remains an economically and statistically significant determinant of EV adoption rates. The temporal and spatial variations of this effect are also quantified, providing a robust foundation for policy implications.
