Abstract:

In recent years, the rapid development of ride-hailing service in China's cities may have a significant impact on the traditional way of travel. An important issue is how it will affect public transport. Based on the rational choice theory, this paper makes an empirical study using the relevant data from 109 cities. The heterogeneity analyses are also conducted according to the time of ride- hailing service entering the city and the category of the city. The results show that: the ride-hailing service has a significant negative impact on the use of urban public transport; as time goes on, the negative impact of ride- hailing service shows a law of first strengthening and then weakening; the negative impact of ride-hailing service is more serious in megacities. This study reveals the influence of ride-hailing on public transport in China’s cities, which can be used as a reference for traffic managers to make relevant policies.
