The characteristic of supervisor responsibility system for post-graduate students is to emphasize the role and importance of supervisors during the educating procedure. However, in such a system the supervisors usually pay more attention on the research work than the ideology of students. Even in some cases, the supervisors may ignore the ideological and political education. This paper takes the supervisors and post-graduate students in Dalian University of Technology as the sample and motivates the full initiative and creativity of all supervisors to devote their enthusiasm and energy to the ideological and political education for post-graduate students. In our work, the joint responsibility of supervisor and group management of the institute is practiced on the basis of the class and institute system of the students and supervisors respectively. In terms of a series of experience and investigation, the mechanism of the ideological and political education for post-graduate students is developed, which is proved to be efficient and effective for the study and academic research activity.
