In this paper, PPM Model is taken as a theoretical framework and an empirical research method is employed to determine the antecedents influencing consumers’ decisions on migrating from PC-based shopping to mobile shopping. We found that inconvenience, security, perceived usefulness, and perceived ease of use are the significant antecedents influencing consumers’channel migration intention of choosing mobile shopping.
