Abstract: The high-quality development of education needs to adhere to the principle of public welfare of education.At present,the cost of high-quality compulsory education is too high for the people in our country,and it is difficult for children from different classes to obtain equal opportunities for high-quality compulsory education,which hinders the public welfare of education.The direct public welfare of education itself is realized through compulsory education and the indirect public welfare of education itself is realized through higher education in our country.The realization of the direct social public welfare of education needs to meet two conditions at the same time:one is that the number of class mobility opportunities that education can provide is enough to trigger competition,and the other is that the opportunity for competition is equally provided to everyone.Due to the “championship” nature of education streaming in our country,equal access to high-quality compulsory education is a necessary condition for realizing the direct social welfare of education.However,there are still deficiencies in the coverage and consolidation rate of compulsory education,the healthy development of private compulsory education,and the supply of high-quality public compulsory education resources in our country.Therefore,for ensuring the public welfare of education,it is necessary to continue to do a good job in controlling dropouts and protecting schools,implementing classified management of private compulsory education schools,reducing the impact of pre-assignment factors on the access to high-quality public compulsory education opportunities,and changing the “championship” streaming model.

Key words: the high-quality development of education, public welfare in education, compulsory education, public education, private education
