In order to give full play to the advantages of local governance structure, it is necessary to explore the influence of governance structure on college students' cultural identity and self-confidence. In this paper, a questionnaire survey was conducted on four college students in Zhejiang Province, and the regression analysis method was used to analyze the survey data. Based on the results, from the perspective of local governance structure, the relationship between local governance structure and college students' cultural identity and self-confidence is demonstrated. This paper puts forward the following hypotheses: first, whether the structure of local autonomy has an impact on the cultural identity of college students; second, whether the relationship between college students' identity and self-confidence is independent; thirdly, whether the local self-control structure can improve the self-confidence of college students; Finally, the influence and degree of local self-government structure and cultural identity of college students on college students' self-confidence. The results show that the local structure can improve the cultural level of college students, with an increase of about 10.5%, and the impact on the cultural self-confidence of college students is relatively small, indicating that there is a correlation between cultural identity and local governance structure, and the correlation between cultural self-confidence is small, and the relationship between cultural identity and self-confidence is independent. The reason for this is that the short-term effect of the local governance structure is significant, and the long-term effect is not good, so it is necessary to cooperate with social participation measures, university system and other measures to enhance students' cultural self-confidence.
