This article analyzes the functions of enterprises and markets, and examines the evolution of enterprise organizations and market organization forms. It discusses the reasons and essence of the existence of enterprise groups. The article argues that enterprise groups are intermediary organizations between enterprises and markets. Under certain conditions, the internal coordination of enterprises can be replaced through market coordination, which can reduce the administrative costs of the organization, without increasing the market transaction costs, thus reducing the cost of economic operation. This is the essence of the enterprise group.
