Enterprises face a higher than fifty percentage of failure with new information systems implementation. Thus, user resistance has become a challenge for enterprises. In order to enhance the administrative efficiency, institutions in the public sectors have invested lots of resources in building E-government, which entails new systems implementation. As in private sector, implementing new systems in public sectors also results in systems failure, because there may encounter resistance during implementation. In the field of information systems, most user resistance research focus on private organizations, but few in public sectors. This research empirically study the user resistance of information systems in public sectors, by sending questionnaire to 82 public officials across different government units, who are using the same information system, and 63 valid responses collected. Data analysis employed is regression analysis. This research shows that switching costs has a positive impact on user resistance; but it shows that both organizational support for change and favorable colleague opinion have negative impacts on user resistance. This research also shows that favorable colleague opinion has indirectly influence through switching costs on user resistance (switching costs as a mediator). Perceived value and self-efficacy for change have no impacts on user resistance. While switching benefits has a positive impact on perceived value, perceived has no significant influence on user resistance.
