The present study examines the factors influencing user intention to use portals in the context of the mobile internet. Based on the Technology Acceptance Model TAM and Triandis models, the present study constructs a research model focused on intention to use portals in mobile internet devices as a dependent variable. In particular, the present study includes a new variable, perceived service-platform fit, to account for the shift in portal use from wired internet to mobile internet. The results show that perceived ubiquitous effect and perceived ease-of-use had effects on perceived consequences, and perceived ease-of-use had an effect on perceived ubiquitous effect. Perceived consequences, perceived ease-of-use, and social factors affected attitude. Perceived consequences and social factors had effects on intention. In addition, perceived service-platform fit had positive effects on perceived ease-of-use and perceived consequences.
