Abstract: Knowledge production has social attribute,which provides the necessity and possibility for the social control of knowledge production.The social control mechanism of different knowledge creates different knowledge structure and metaphysics of different nations. Chinese feudalism dynasty developed a set of strict knowledge society control mechanism by the formidable political power,finally forming knowledge production "model" different from that of the western nations.In this model,Confucianism realized its own duplication by the way of "concentric circle",while natural science studies being ignored,which thus made Chinese science and technology fall behind in the modern times.
