Abstract: In the context of the connotative development of higher education, the construction of the graduate supervisor team has become a core issue in improving the quality of talent cultivation. As the responsible party for the quality of graduate education, mentors play a key role in academic guidance, research training, and career development, and their management effectiveness directly affects the effectiveness of cultivating high-level innovative talents. By establishing a sound multi-dimensional evaluation system, establishing differentiated incentive mechanisms, improving the mentor training and development system, optimizing the dynamic management system of teacher-student relationships, and achieving digital transformation of the management system, universities can optimize the mentor management system, enhance the professional level and academic guidance ability of the mentor team, and promote the high-quality development of graduate education.
