As a core concept in service post-adoption research, satisfaction is defined as “the summary psychological state resulting when the emotion surrounding disconfirmed expectations is coupled with the consumer's prior feelings about the consumption experience” (Oliver, 1981). Human migration research also takes satisfaction or dissatisfaction as a primary push factor that drives individuals away from the original place (Bansal et al., 2005). Prior studies have shown the negative impact of satisfaction on users' intention to switch service providers, such as email services (Kim, Shin, & Lee, 2006), blog services (Zhang et al., 2008), and Web browser service (Ye et al., 2011).
