Theoretically, the present thesis is based upon the encouragement theory in the study of administration. The literature of the thesis is mainly devoted to the survey of research at home and abroad in two aspects: the young teacher development and encouragement mechanism. Methodologically, the thesis is a case study of Northwest Normal University. With the statistical analysis of the status quo of teaching and research, as well as the demand of research of the young teachers in the university, the thesis treats the current encouragement system, summarizes the conspicuous problems and then advances countermeasures in the research enragement system of young teachers in these universities based upon the qualitative and quantitative studies.
