Abstract

This paper verifies the causal relationship between electric vehicles (EVs) promotion and improvements in air quality in China using the Difference-in-Differences (DID) estimation method. By combining the installation dates of new charging piles within prefecture-level cities with station-level air pollution data, we estimate that the PM2.5 decreased by 3.326

after the installation of new charging piles. Mechanism tests indicate that EV promotion led to a reduction in emissions of pollutants directly associated with fossil fuel vehicles. Although EV promotion increased the sales volume of EVs, it did not exacerbate pollution by causing traffic congestion. Instead, it improved air quality by increasing the EVs proportion within cities. Heterogeneity test results show that improvements in air quality are particularly sensitive to EV promotion in developed regions in China. These findings demonstrate the effectiveness of promoting EVs to reduce air pollution in developing countries.

期刊介绍： The Journal of Asian Economics provides a forum for publication of increasingly growing research in Asian economic studies and a unique forum for continental Asian economic studies with focus on (i) special studies in adaptive innovation paradigms in Asian economic regimes, (ii) studies relative to unique dimensions of Asian economic development paradigm, as they are investigated by researchers, (iii) comparative studies of development paradigms in other developing continents, Latin America and Africa, (iv) the emerging new pattern of comparative advantages between Asian countries and the United States and North America.
