Aiming at the main problem of the imbalance between supply and demand of shared cars in terms of time and space, by collecting the usage data of shared car users in Beijing, the high-frequency usage stations and peak hours are analyzed and obtained. Design a questionnaire based on the three dimensions of socio-economic attributes, time of car use and space of car use, and go to the high-frequency stations during the high-frequency hours to carry out field surveys on the users. The results show that most of the car sharing users in Beijing are male office workers who own private cars; the time of using the car is concentrated in the weekdays during 7: 00~9: 00, during 17: 00~19: 00, and in bad weather; the location of using the car is mostly near the transport facilities and business districts, which is a clear feature of commuting; and the 5 qualitative factors, including age and occupation, and six quantitative factors, including frequency of use, affect the satisfaction of the users significantly. Strengthening vehicle scheduling during morning and evening peak hours and inclement weather, setting up more one-way return stations in inner-ring business districts, and lowering the cost of time-share models are the key solutions to the problem.
