This study explores the factors influencing university students’ social entrepreneurial intentions based on the values-beliefs-norms theory. Data were collected from 769 Chinese university students through online surveys. The hypotheses were tested using partial least squares-structural equation modeling. The results confirmed the positive influence of altruistic and traditional values on normative beliefs. Awareness of the consequences and attribution of responsibility had no significant effect on personal norms among university students, which have been discussed in-depth in relation to the phenomenon of inadequate student socialization due to closed-loop management policies at Chinese universities during the COVID-19 pandemic. Furthermore, the findings verified the positive and significant effects of personal, injunctive, and descriptive social norms on social entrepreneurship intentions. With the aim of promoting social entrepreneurship among university students and broadening the understanding of the phenomenon of social entrepreneurs, this study provides a favorable direction and expands the discussion on the topic. The results will help the government and universities foster more effective prosocial behaviors among university students.
