After the development at the end of the last century, the Chinese art market has ranked among the top in terms of market scale at the beginning of this century. However, there still exists a potential trillion-level market for cultural demand in China’s art consumption market. Based on this issue, this paper, drawing on the “2023 Art Market Report” released by Artron Art Market Monitoring Center, discusses the development and current situation of China's art consumption market, supply and demand conditions, as well as the relationship between the deficiencies in the art market and public aesthetic education, from three aspects: China’s art consumption market, supply and demand in China’s art consumption market, and deficiencies in China’s art market and public aesthetic education. It is concluded that the potential trillion-level market for cultural demand is not only a problem of economic market gaps but also a deficiency in aesthetic education.展开更多
