Study on the Influencing Factors of Private Car Ownership in China under the Background of Aging

In recent years, with the increasing number of motor vehicles in cities, urban traffic jams, air pollution and other problems have become increasingly prominent. There are a variety of factors affecting road congestion in China, including population, economic factors, urban morphology and policy factors. Among them, the population factor is particularly important, because our country has stepped into the aging society since 1999. In this paper, the factors affecting private car ownership in China are studied, and the aging population in China is taken as the main entry point to find effective ways to control traffic congestion in China. In this paper, it is concluded that aging of population has a significant positive effect on private car ownership in all provinces, however, it is not certain by region. GDP has a significant positive effect on private car ownership in all provinces. The main routes of public transport operation have a significant positive impact on private car ownership in all provinces. Bus routes have a significant positive impact on private car ownership in all provinces. According to the research results, this paper puts forward relevant policy recommendations.
