Analysis of Factors Influencing China’s New Energy Vehicle Sales from the Perspective of Spatial Spillover Effect

新能源汽车的销量在一定程度上能够映射出各省的绿色发展情况，在本研究中采用多元线性空间杜宾模型分析中国各地区新能源汽车销量的影响因素及其空间溢出效应。研究发现，经济增长、政策支持和社会环保意识显著促进了新能源汽车销量，且存在显著的空间溢出效应。东部和西部地区对周边省份有正向影响，而中部和东北部地区影响较小。根据实证研究结果为政府推动绿色、低碳经济提供了策略建议，以实现区域间的协同发展，共同推进绿色能源行业的繁荣。The sales of new energy vehicles can reflect the green development of each province to a certain extent. In this study, the multivariate linear spatial Durbin model was used to analyze the influencing factors of new energy vehicle sales and their spatial spillover effects in various regions of China. The study found that economic growth, policy support and social environmental awareness significantly promoted the sales of new energy vehicles, and there were significant spatial spillover effects. The eastern and western regions have a positive impact on surrounding provinces, while the central and northeastern regions have a smaller impact. Based on the empirical research results, it provides strategic suggestions for the government to promote green and low-carbon economy to achieve coordinated development among regions and jointly promote the prosperity of the green energy industry.
