In China, the discipline catalog is not only the basis for postgraduate enrollment, cultivation, employment and setting of doctoral programs, but also the basic unit for evaluation and assessment of domestic disciplines and evaluation and funding of “double-class” construction, as well as the reference for undergraduate enrollment majors (the setting of undergraduate teaching supervisory committee also refers to the discipline categories of postgraduate students). Therefore, the discussion of the disciplinary catalog has a positive significance for the future development of the discipline. This paper provides a preliminary interpretation of several issues in the first-level discipline setting of art (academic) disciplines in this discipline catalog adjustment, and puts forward targeted suggestions on the correspondence between art disciplines and first-level disciplines, the setting of interdisciplinary disciplines and the positioning of two controversial disciplines, design and art theory.
