1. Academic authority: Doctoral tutor is an important role in the higher education system, representing academic authority and research level. He has profound knowledge and professional background in his own field, and has made important contributions to the development of academic circles by guiding graduate students' academic research. Deputy departmental level cadres are mainly engaged in administrative work, with weak professional background and academic attainments.

2. Career development and social influence: doctoral supervisors have high career development potential and social influence in academia. You can improve your academic reputation and status by publishing high-level academic papers and getting funding from scientific research projects. The career development of deputy department-level cadres mainly depends on administrative promotion and government appointment, which is relatively limited.
