Currently, aesthetic education in higher education in China faces the dilemma of dispersed resources and poor results. The allocation of aesthetic education resources is not balanced, the degree of social participation is not high, and there is a lack of effective articulation between correctional education in prisons and aesthetic education in colleges and universities. In this paper, we constructed the “prison – university – community” trinity synergistic aesthetic education resource integration mechanism, and explored the optimization of social aesthetic education resource allocation path. Using experimental method, interview method, questionnaire survey method and other research methods, with 856 sophomore students in key undergraduate colleges in province A as the research object, 60 students were randomly selected into the experimental group and the control group of 30 people each, using one-way analysis of variance method for data processing. The study constructed a synergistic pathway led by universities, corrected by prisons, and expanded by communities, which was practically verified through the three dimensions of aesthetic education literacy, aesthetic education skills, and basic theoretical knowledge of aesthetic education. The results showed that the mean value of aesthetic literacy in the experimental group reached 3.891, significantly higher than that of 2.60 in the control group, with a P-value of 0.004; the mean value of aesthetic skills in the experimental group was 3.981, and that of the control group was 2.694; and the P-value of the test of basic theoretical knowledge of aesthetic education in the experimental group was 0.001, which showed a significant difference. The trinity synergistic path is effective in enhancing the comprehensive quality of students’ aesthetic education, and provides an effective practical model and theoretical support for the integration of social aesthetic education resources.
