Legal Basis: Million Enrollment Expansion: In the new era of China's higher vocational education, higher vocational colleges generally adopted the "school-enterprise" mode in talent training mode, that is, after students enter school, higher vocational colleges implement teaching according to a unified talent training plan, and the teaching process highlights the requirements of higher vocational education of "combining work with study" and "integrating production with teaching". In fact, the talent training objectives of more vocational colleges are not targeted, and the proportion of training according to orders is very small. Most of the students enrolled in this enrollment expansion are on-the-job personnel with certain work experience. In view of this kind of students, the talent training mode of higher vocational colleges must be changed to "enterprise-school" mode, and a new talent training mode has emerged by adopting the mode of "combining work with study", "alternating work with study" and "delivering to the door".
