Abstract: Based on the field survey data of Hefei, this paper focuses on the analysis of how four micro factors —consumers' personal characteristics, family characteristics, shared car travel characteristics, and experience of using shared cars—influence the frequency of consumers using shared cars. The study found that factors such as consumers' gender, age, car ownership, monthly household income, awareness of shared cars, deposit, charging convenience, and costs will significantly affect consumers' willingness to use shared cars. Among them, men, higher monthly household income, higher awareness of shared cars, and more convenient charging will lead to higher frequency of shared car use. Older age, a higher deposit, household car ownership and a higher cost will lower the frequency of car sharing.

Key words: shared car, willingness to use, Hefei city, micro-influencing factor
