Influenced by the backward management methods and other factors, the integration and sharing of digital educational resources in colleges and universities have certain problems, and cannot give full play to the advantages of digital educational resources in colleges and universities. Based on this, this study proposes a targeted digital education resources integration strategy, using particle swarm algorithm to optimize the sorting of digital education resources, to obtain high-quality digital education resources, introducing fuzzy clustering algorithm and combining with the principle of decision tree, to accurately classify and integrate digital education resources. On the basis of realizing the integration and classification of digital educational resources, a digital educational resource sharing model is formed to promote the effective use of digital educational resources. The digital educational resources integration strategy proposed in this paper is adopted to carry out the application practice of digital educational resources integration and sharing in S colleges and universities. The mean values of the three dimensions of students’ learning attitude, teachers’ teaching, and teaching effect in S colleges and universities reached 3.48, 3.97, and 3.74, respectively, and this paper’s digital educational resources integration strategy method has a positive positive impact on the dimensions of students’ learning attitudes, teachers’ teaching, and teaching effect in Civic and Political Education in S colleges and universities.
