Under the background of the construction of independent knowledge system, the construction of Chinese philosophy and social science preprint platform is of great value: Enhance the subject consciousness of philosophy and social science research to encourage original innovation. Build an independent communication system of philosophy and social science to improve the discourse advantage; an open exchange ecology of philosophy and social science to solve the monopoly problem. Promote the prosperity and development of philosophy and social science to present a panoramic view of knowledge. The construction of the philosophy and social science preprint platform should rebuild the new ecology of academic exchanges and dissemination, support the three systems and the inderpendent knowledge system as the goal, adhere to the concept of taking the academic community as the center, taking regulations and systems as the guarantee, and taking information technology as the support. Its overall framework can be grasped from the seven constituent elements of ideology, organization, mechanism, system, management, business and technology.
