The catalogue of disciplines issued in 2022 has made great adjustments to the categories of arts, among which the adjustment of professional degrees is a highlight. For the first time, professional degrees are listed alongside first-level subjects in the same catalogue. The ratio of professional degree to first-level discipline is 6:1, occupying an absolute advantage. The level of education for professional degrees is also upgraded from master’〖KG-*4〗s degree level to doctoral degree level. This indicates that in the future, the main body of art high-level talent education is in the field of professional degrees. The first-level discipline “arts” is the only first-level discipline in the new subject catalog, and its boundary has been greatly broadened. It forms a new relationship with professional degrees that is interdependent and complementary, equal and parallel. These changes pave the way for the construction of the discipline system of arts with Chinese characteristics in terms of discipline system and knowledge system.
