Since China??s disciplinary system upgraded art science to a discipline category in 2011, under the specific background of discipline construction and development, the research on the connotation and common characteristics of the discipline in China??s art academia has been paid more attention to, especially the integration and interpretation of different art history presentations, and the discussion on the promotion of interdisciplinary and interdisciplinary art history research, which has caused more and more academic controversy Talk about the topic. In view of this, I presided over the major project “Research on the theory and method of cross category art history” sponsored by the national social science art foundation in 2020, and put forward a clear concept that the research on art history and art history itself need an integrated research of “cross category art history”, which is to open up and cover the arts including music, dance, drama, opera, film and television, folk art, art and design. The study of comprehensive art history of quasi art has the characteristics of cross category penetration and mutual integration. Therefore, the study of art history can be called the historical study of “art common history” or “general art history”. What supports it is the research on the theory and methodology of art history, which is the key to generalize the whole art history and art history research, and an important premise to promote the research of art history and art history itself.
