The socialization of public cultural service has its profound theoretical basis，and it is an inevitable requirement of government governance reform and the special law of cultural development under the guidance of new public administration theory. Besides，it is also an important part of the realization of national cultural governance system and modernization of governance capacity，as well as the construction of our country’s modern public cultural service system. Although currently lots of beneficial practice has been done for the socialization of public cultural service，the overall level remains at a relatively primary and unsystematic stage. Next stage requires further transform of government functions，the promotion of internal reform in nonprofit public cultural institutions，the enhancement of endogenous capacity of social organizations，and the improvement of social participation mechanism in order to promote the socialization of public cultural service. <<
