Abstract

Abstract: The transport sector, as one of the principal source of air pollution, has attracted a growing attention in academia in recent years. By employing the LMDI method, this paper focuses on the driving factors of pollution in transport sector based on the pollutant emission data of motor vehicles from 2010-2018. The results show that the production effect is the main driver for the changes of NOx and PM emissions in the transport sector, while for HC, pollution intensity effect is the largest contributor. The pollution intensity effect reduced NOx and PM emission by 307% and 381%, respectively, which plays the dominant role in reducing their emissions. Compared to other effects, the structure effect and the vehicle effect make minor contributions to the changes of pollutant emissions.
