This paper utilizes the idea of information diffusion to model the diffusion effect of information on civic and political education and categorizes the elements for the impact of the civic and political information diffusion system from the three levels of dissemination, acceptance and control. In order to verify the validity of the Civic and Political Information Diffusion Model, manipulative tests and empirical analysis are carried out. The results show that the breadth and depth of the Civic and Political Information Diffusion Model’s manipulability test Sig are significant. They are both less than 0.05, with significant differences. The specific factors affecting the integration and development of civic education and student management can be analyzed more intuitively from the three levels of dissemination, acceptance, and control. This shows that the use of the information diffusion model can provide an effective research direction for the development of the integration of civic education and student management in colleges and universities and lay a good foundation for the cultivation of high-level talents adapted to the development needs of the new era.
