社会系统演化的一个新理论模型

Social system is an open, dynamic and active complex system, about which a mass of theories and methods have been achieved. However these theories and methods are stamped with reductionism more or less when understanding the essence of the system, so they can't well reveal the essence of the organic social system. In the paper, a new understanding about the essence of the social system is proposed, and then the dynamic equation that controls the generation and evolution of social system can be got. In this way the new theoretical model is got, which is used to describe the social system and further reveal the law of development and evolution of social systems. Feudal society, as a kind of state at a certain stage of social development, inevitably coincides with the law governing the social development. In the paper, Chinese feudal society is taken as typical example and is analyzed using the new theoretical model, and then the reason of its long continuity can be partially found.
