Abstract: On the basis of clearly defining the connotation and the function types of business structural organization, this paper makes use of the knowledge foundation theory to find the knowledge logic coexisting between the enterprise and its outside environment, institutional environment and social relationship networks, then it constructs an integrated model with closed loop and puts forward such a research subject: the tool engineering and knowledge technology in the external technical environment can influence corporate institutional structuralization and hierarchy structuralization through efficiency mechanism; the humanity-cognitive knowledge in the external institutional environment can influence the corporate cultural structuralization through social regulation mechanism, the regulatory knowledge can influence the corporate institutional structuralization through the forcing mechanism, the criterion knowledge can influence corporate hierarchy structuralization through the imitation mechanism; and the external social relationship network can influence corporate hierarchy structuralization through the network utility mechanism. This model can not only interpret the phenomena of business structural organization, but also provide a theoretical framework for further empirical researches.

Key words: structural organization; explanation mechanism; knowledge system; an integrated model with closed loop
