Abstract: Although the senior secondary school enrolment rate in China has been enhanced in recent years, some practical problems can still be identified: the imbalance of student proportion between academic and vocational high schools; the institutional barriers between the academic and vocational high schools; the homogeneity of academic high school; the insufficient attraction of vocational high school. The main challenge in the senior secondary educational development is how to realize connotation development along with the popularization of high schools. From the perspective of cunty level endogenous development, this paper proposes several solutions to reinforce the quality of education in senior secondary stage, including: re-framing the policy system; optimizing the structural layout; promoting the integration of academic and vocational education; establishing cooperation mechanisms. The eventual policy aim is to cultivate the contributors and successors of socialism who develop morally, intellectually, physically and aesthetically in an all-round way.
