The art consumption behavior and concept of the public in the new period of the development of artificial intelligence has changed dramatically, and the fundamental reason is the change of art consumption psychology, which pays more attention to the spiritual and psychological satisfaction of art consumption. Based on the analysis of art consumption psychology and consumption behavior, the article establishes the basic mapping mechanism of art consumption psychology and behavior change. Then, based on the theory of planned behavior, a structural equation model was established by choosing art product cognition, emotional response, volitional control, and attitude as independent variables, and art consumption behavior intention as dependent variable. And a questionnaire was designed based on the above variables, so as to verify the correlation between art consumption psychology and behavioral changes. Through the analysis of examples, it can be seen that the individual’s cognition of art products, emotional reaction and volitional control ability in art consumption psychology will have a positive and significant influence on their art consumption behavior, and attitude has a more obvious mediating effect between the above variables. In the era of artificial intelligence, it is necessary to fully explore the individual’s cognitive level of art products and volitional control ability, and to enhance their art attitude with emotional reaction, so as to empower the diversified development of art consumption behavior.
