Master-doctor continuous reading is an academic training mode, which aims to improve the efficiency and quality of postgraduate training. According to the regulations of the Ministry of Education, the enrollment quota of graduate students and doctoral programs in all disciplines of each enrollment institution does not exceed 40% of the total enrollment plan of this discipline, which means that there are relatively many graduate students and doctoral programs in the enrollment plan of each discipline. Some high-level universities and research institutions are also actively promoting postgraduate and doctoral programs to provide more opportunities for students who are interested in further study. Therefore, in general, compared with the number of direct doctoral students, there are relatively more places for graduate students and doctoral students.
