This study proposed ubiquitous connectivity and context-based provision as unique characteristics of the mobile commerce environment that differentiate it from the existing electronic commerce environment, and tested whether a technology acceptance model incorporating these mobile-specific characteristic variables improves the explanatory power for mobile commerce adoption intention compared to the conventional technology acceptance model. The empirical analysis confirmed that a technology acceptance model newly incorporating ubiquitous connectivity and context-based provision—the distinctive characteristics of the mobile commerce environment—achieves a significant improvement in model fit over explaining mobile commerce adoption intention with the conventional technology acceptance model alone. Furthermore, the significant effects of ubiquitous connectivity and context-based provision on perceived usefulness were confirmed. In particular, context-based provision was found to directly influence mobile commerce adoption intention. Based on the empirical results, strategic implications were presented regarding integrated customer communication channel strategies and effective CRM strategies focused on context.
