低碳经济政策驱动新能源汽车产业发展——基于中介效应模型分析
Low-Carbon Economic Policy Drives the Development of New Energy Vehicle Industry—Based on the Analysis of Intermediary Effect Model

新能源汽车产业的发展离不开低碳经济政策的支持，在低碳转型快速发展的背景下，低碳经济政策的实施在其中发挥着重要的作用。本文通过运用2016~2023年中国31个省级面板数据建立模型，通过熵权法对指标进行客观赋权并计算低碳经济政策实施效果和新能源汽车产业的发展水平，分析我国低碳经济政策与新能源汽车产业的发展情况，并验证低碳经济政策对新能源汽车产业发展的驱动效应和中介效应，最后通过模型的内生性检验和稳健性检验来确保结果的准确性。研究与分析结果表明，从整体上看我国省级低碳经济政策发展水平在2016~2023年间均成上升趋势；在回归分析中，低碳经济政策对新能源汽车产业的发展具有明显的正向驱动作用；在中介效应中，本文通过居民收入水平这个中介效应可以有效推动新能源汽车产业的发展。因此，根据这些结论，要重视经济增长的影响即居民收入水平的提高，推动低碳经济政策助力新能源汽车的快速发展和市场的扩大，加快可持续经济发展。
The development of the new energy vehicle industry is inseparable from the support of low-carbon economic policies, and the implementation of low-carbon economic policies plays a significant role in the context of the rapid development of low-carbon transformation. This paper establishes a model by using the panel data of 31 provincial governments in China from 2016 to 2023, objectively weights industry and through the entropy weight method, calculates the implementation effect of low-carbon economic policies and the development level of the new energy vehicle industry, analyzes the development of China’s low-carbon economic policies and the new energy vehicle industry, and verifies the driving and mediating effects of low-carbon economic policies on the development of the new energy vehicle industry, and finally ensures the accuracy of the results through the endogeneity test and robustness test of the model. The results show that, overall, the development level of provincial low-carbon economic policies in China has shown an upward trend from 2016 to 2020. In the regression analysis, low-carbon economic policies have an obvious positive driving effect on the development of the new energy vehicle industry. In the mediating effect, this paper can effectively promote the development of the new energy vehicle industry through the mediating effect of residents’ income level. Therefore, according to these conclusions, it is necessary to pay attention to the impact of economic growth, that is, the improvement of residents’ income levels, promote low-carbon economic policies to help the rapid development of new energy vehicles and the expansion of the market, and accelerate sustainable economic development.
