Based on the American Customer Satisfaction Index( ACSI) Model,the present study constructed the passenger satisfaction model of tailored car-sharing service and verified the model empirically by summarizing the features of tailored car-sharing service.The model consisted of six variables: passenger expectation,perceived quality,perceived benefit,perceived risk,passenger satisfaction,passenger complaints and passenger loyalty. To verify this model,267 passengers who used the service participated a questionnaire survey,and the feasibility of this model was confirmed. This study is conducive to improving the theory of customer satisfaction,providing theoretical guidance and support for managers to develop passenger satisfaction promotion programs,and contributing to the development of related enterprises within the industry.
