Abstract: In view of the defects of the current public cultural service provision model in China, this paper puts forward the concept of "endogenous supply" of community public cultural service. The research on the supply mode of public cultural service in Y community finds that Y community implements the endogenous provision of community public cultural services basically through the excavation of social resources, the integration of regional characteristics of cultural resources, participation in competition and the pursuit of government financial support and recognition and so on. To achieve the sustainability of endogenous supply of community public cultural service, the community should be supported by the government, strengthen their own construction to activate endogenous forces, integrate the resources to promote community integration and participate in market competition to foster community spirit.

Key words: community, public cultural service, independent supply, endogenous supply
