Beomg recognized as one of the most important causes for the failure of information system. The user resistance factors have become the key issues on MIS research field. This paper not only reviews the previous literatures, searchs for predominant resistant factors, but also analyzes the relationships between user's characteristics (i.e. age, education level, job position) and the resestance factors. Ninty five end user opinions are collected and analyzed. Among them eight major resistance factors are explored. By using factor analysis technique, six predominant dimensions of the user resistance are formed, which are: "Change of Job Satisfaction", "Expectation & Requirement for the Information Systems", "Change of Power & Autonomy" and "User Assistance & Esteem". At last some conceivable implications of the finding are also proposed.
