The Impact of Car-Sharing on the Use Dependency of Private Cars

Due to the development of motorization and car-sharing market, the influence of car sharing in China is different from those of western developed countries. In this paper, through investigation of car-sharing users, the impact of car-sharing on the dependency on private cars is studied. Binary logit model is built to study the influence of factors on car use frequency, for users whose car use increased significantly after trying car sharing. Results show that for users with good accessibility of car-sharing stations, low annual household income, poor accessibility of public transport, and high satisfaction of car-sharing are likely to increase private car use. The development of car sharing in China is likely to enhance the reliance on private car use, due convenience, and cost advantages. Car-sharing in China should be used as an auxiliary means for urban public transport, and needs moderately controlled development.
