Abstract: 【Purpose/significance】In the context of actively promoting the development of AI education, it is a key issue to explore
which factors cause users to continue to use the AI learning platform.【Method/process】This research uses family SES (social eco-
nomic status) inequality as a research scenario, and builds a research model of factors that influence the continuous use of the AI learn-ing platform of middle school students based on the theory of planned behavior. By clustering SES into groups, and comparing the sig-nificance of the path coefficient difference between the advantages and disadvantages of the two groups during model testing, the effect of the SES differences on the factors related to the continuous usage intention is studied.【Result/conclusion】Subjective norms and perceived behavior control are the direct factors influencing users' continuous usage intention. Learning utilitarianism, learning enjoy-ment, self-efficacy, perceived ease of use, and accessibility indirectly affect the continuous usage intention, among which attitude has no significant effect. SES has a moderating effect on the positive relationship between self-efficacy and perceived behavior control.【Innovation/limitation】This study introduces the user's intrinsic motivation and the internal factors of the AI learning platform to ex-pand the theory of planned behavior. It needs further analysis on the research level of groups with different education levels.
