Abstract: Objective To establish an evaluation model of scientific impact of supervisors and provide reference for the construction of supervisor team. Methods Based on the literature review, a series of evaluation index were selected; and 62 supervisors for doctor degree from a well-known hospital in China were selected.Their academic conditions were evaluated by Factor Analysis. Results The evaluation of supervisors' scientific impact mainly determined by three common factors including research output factor, research input factor and academic publication factor. The total variance contribution rate of three factors reached 75.25%.There were significant differences in the scientific impact of supervisor. Totally, superisors' research input was greater than their research output. Conclusions Factor Analysis can be used to construct the evaluation model of supervisor's scientific impact. At the same time, it is of great significance to evaluate the scientific impact of supervisor for the selection of high-level mentors and the construction of supervisor team.
