Abstract In this research, we empirically investigate the influence of users’habit on their sustained usage behavior in the information context of China. First of all, based on the information technology acceptance model，the information system continuance model and other related theories, we take the habit as a key factor to construct the theoretical model and put forward the research hypothesis. Secondly, we use statistical data to test the reliability, validity of constructs and path analysis of the model. Considering the importance of habit, we propose that habit mediates the relationship between the antecedents of habit and sustained usage. It is confirmed that habit has a significant influence on the sustained usage of postadoption users. And it also has an obviously mediating effect between the satisfaction degrees, system easy to use, system using importance, convenience, continuance commitment and continuance using behavior.
