The general enrollment system is a hot issue in the field of higher education reform. And the scientific cognition of its historical evolution, internal logic and dynamic mechanism is helpful to promote the reform of China's undergraduate enrollment system. From the perspective of historical institutionalism, the evolution of Chinese enrollment categories can be divided into four major historical stages: historical gestation, preliminary exploration, rapid rise and in-depth development. Tracing the hidden institutional logic behind the policy, it is found that the initial conditions, positive feedback mechanism and mindset make the change of the major enrollment system have a strong path dependence. In terms of dynamic mechanism, politics, economy and society constitute the basic factors of institutional change; learning effect, adaptive expectation and resource optimization orientation constitute the internal driving force of self-strengthening in the system; and the interest game among various action subjects constitutes the direct driving force of institutional change. In the future, the major enrollment system will accelerate the comprehensive reform of higher education through the three aspects of deepening rational practice examination, enhancing cross-cultivation and exploration, and promoting the transformation of human-oriented management, so as to enable the connotative development of higher education.
