Future research will explore the reflective and formative dimensions first, and then identify the perception value of online booking from the Internet factors, tourism service factors, social media factors and consumer individual factors. The Internet factors may include perceived risk, convenience, website quality, flow experience and transparency. The tourism service factors may include price dispersion and product differentiation [55]. The social media factors may include the credibility, valence, rating and the review response dimensions. The consumer individual factors may be self-efficacy, travel motivation, gender, age, innovativeness and involvement. Furthermore, the effect of perceived value of online booking on rebooking online and contributing in social media needs empirical validation.
