Purpose The main purpose of this study is to examine whether the expectations and outcomes of the bicycle-sharing service significantly influence users' expectation disconfirmation, satisfaction, and continuous intention to use. In addition, we will verify the moderating effect of social interaction in bicycle-sharing service on the relationship between satisfaction and continuous intention to use. Design/methodology/approach Based on previous studies dealing with determinants of bicycle use, users' expectations and outcomes of the bicycle-sharing service were measured by three variables; accessibility, convenience, and safety. To collect the data, we conducted a survey of undergraduates at a university located in Seoul for three weeks, beginning March 6. Participants completed the first questionnaire, which measured expectations of the bicycle-sharing service based on the attributes and social interaction before using the BSS. After a few weeks, the same participants completed the second questionnaire, which measured outcomes of the outcome, disconfirmation, satisfaction, and continuous intention to use the BSS. Only participants who completed both surveys received monetary compensation. In order to test hypothesis, the Smart Partial Least Square (SmartPLS) modeling technique was applied. Findings In terms of main effects, based on the expectation disconfirmation theory, the results indicated that there were significant relationship among expectation, performance, disconfirmation, and satisfaction. In particular, it was verified that disconfirmation completely plays a mediating role between performance and satisfaction. In addition, the moderating effect of social interaction was examined. There was a significant interaction effects of social interaction and satisfaction on the continuous intention to use for leisure purpose. Finally, this study is expected to contribute to the study of resource sharing in the field of tourism and provide baseline information for future research.
