Abstract-as the intelligent mobile device terminals, such as smartphone and tablet, more and more pervasive and affordable, mobile commerce has become the hottest issue around the world. User acceptance is one of the key fundamentals for development and success of mobile commerce. Build on the Unified Theory of Acceptance and Use of mobile commerce and its recent extension for mobile commerce, we proposed a study design and a theoretical research model to investigate acceptance of mobile commerce by users. As technology adoption research is still dominated by quantitative methods, the study in this paper combines qualitative and quantitative phase.
