Social and emotional competence is an important breakthrough in the development of high-quality education. Under the background of the digital intelligence era, digitization and intellectualization have changed the traditional way of education. College learning shows the characteristics of intelligence, systematization, and fragmentation, as well as the diversification of knowledge production and dissemination, which poses a new challenge to the cultivation of college students' social and emotional competence. At present, there are serious deficiencies in the social and emotional competence of Chinese college students, that is, the deviation of self-consciousness and self-management abilities, the lack of social consciousness and interpersonal skills, the weak ability to make responsible decisions, and so on. Combined with the characteristics of digital intelligence education, this paper puts forward some useful countermeasures to improve college students' social and emotional competence from six aspects. They are to establish the principles of student-centered education, to bring mathematical literacy and social and emotional competence into teachers' professional construction standards, to bring social and emotional education into the school curriculum, to integrate social and emotional education with an intelligent teaching environment, to take social and emotional competence as an important part of educational evaluation, to enhance students' sense of belonging on campus, and to build a new type of teacher-student relationship.
