While online technologies and applications are rapidly and widely utilized and adopted in e-commerce, it is extremely important to better understand the perceptions of consumers’ use, and acceptance in mobile commerce (MC). This paper adopts the extended technology acceptance model (TAM2) and integrated it with the innovation diffusion theory and the perceived risk variable to model users’ acceptance of using MC. An Empirical study was conducted, the proposed research model was evaluated by structural equation modeling, and then confirmatory factor analysis was applied to test if the empirical data confirmed to the presumed model.
