Jian JIN, Hemin WANG


This paper deals with the relationship between possession of private vehicles and air quality, applying panel data model and based on the data in 31 provinces of China from 2003 to 2009. The research shows that there is hardly positive correlation between them in the provinces in China. On the contrary, the correlation between them is negative in most of the provinces. As a result, we conclude that private vehicles don’t cause serious air pollution and there must be other more essential factors that cause air pollution.
Key words: Possession of private vehicles; Air quality; Panel data model

Résumé: Cet article traite de la relation entre la possession de véhicules privés et la qualité de l'air, en utilisant le modèle de groupe de données et basé sur les données dans 31 provinces chinoises de 2003 à 2009. La recherche montre qu'il n'y a guère de corrélation positive entre eux dans les provinces en Chine. Au contraire, la corrélation entre eux est négative dans la plupart des provinces. En conséquence, nous concluons que les véhicules privés ne causent pas de pollution de l'air grave et il doit y avoir d'autres facteurs plus essentiels qui causent la pollution de l'air.
