The effect of consumer participation in online social networking activities on their susceptibility to influence is investigated in a context of restaurant consumption. This research identified a positive relationship between consumers engagement in social networking sites (SNS) on their susceptibility to global consumption influence, which is a multidimensional factor consisting of conformity to trend, social prestige, and quality perception. Furthermore, consumer engagement in SNS and susceptibility to global consumption influence positively affect social influence on SNS. That is, consumers with higher participation in SNS are more prone to global consumer convergence and peer influence on SNS. As implications for tourism and hospitality businesses, strategies to manage consumer-to-consumer communication on social media are suggested.
