Research on the External Effects of Chinas New Energy Vehicles

Based on the analysis of externality theory, this paper firstly concludes that new energy vehicles have energy security effects, industrial correlation effects, and environmental protection effects, and makes corresponding calculations. Secondly, using real options to evaluate them, the three levels of option value are obtained. Third, analyze the factors that affect the external effects of new energy vehicles, and establish a regression model to obtain the positive impact of new energy vehicle subsidies and oil reserve-production ratio at the macro level, while the secondary industry investment, crude oil prices, and Keqiang index are inverse. Impact; at the meso level, subsidies, renewable energy consumption, and the proportion of clean energy power generation play a positive role, and the monthly average PM2.5 concentration and car price index play a negative role; at the micro level, the proportion of clean energy power generation, subsidies, The number of new energy vehicles per capita and the percentage of fixed asset investment completed in the tertiary industry have a positive impact, while the Keqiang Index has a negative impact. Finally, according to the research results, put forward corresponding countermeasures and suggestions.
