abstract: This dissertation examines travelers’ innovation adoption and repurchase behaviors in the sharing economy. The central question is to what extent the tourism industry embraces service innovations in the sharing economy. Predicated upon behavioral reasoning theory, this research makes a contribution to the tourism study and diffusion of innovation literature, by exploring the influence of travelers’ reasonings in the innovation decision process. The dissertation follows a two-study format. The analysis contextualizes reasons for and against adoption, by incorporating appropriate constructs relevant to service innovations in social dining services (Study 1) and ride-sharing services (Study 2). An exploratory mixed methods approach is taken in both studies. The survey data and the semi-structured interviews are used to identify the context-specific reasons for and against adoption. And, a series of statistical analyses are employed to examine how reasonings influence intentions to adopt social dining services (Study 1) and intentions to repurchase ride-sharing services for the next trip (Study 2). The main results suggest that both reasons for and reasons against adoption have countervailing influences in the psychological processing, supporting the validity of the research models. The findings also reveal that different psychological paths in travelers’ adoption and repurchase intentions. In Study 1, the trustworthiness of service providers attenuates the reasons against adoption and enhances the likelihood of adopting social dining services in the pre-adoption stage. In Study 2, attitude strength functions as an additional construct, which mediates travelers’ attitudes and ultimately intentions to repurchase ride-sharing services for the next trip in the post-adoption stage. By developing and testing a framework comprising a set of consumers’ beliefs, reasonings for adoption and resistance, attitudes towards adoption, and behavioral responses to the sharing economy, the insights gleaned from this research allow practical recommendations to be made for service providers, platform providers, and policy makers in the tourism industry. / Dissertation/Thesis / Doctoral Dissertation Community Resources and Development 2019
