City complex building, the inevitable product of a certain level of economic and social development, which contains commerce, office, residential, hotels, restaurants, conference, exhibition, entertainment and other functions, is the composite building form of human physiology and psychological needs highly concentrated, and the embodiment of urban "organic symbiosis" concept.

The booming of large commercial buildings rapidly infects city planning and design of commercial building in our country. However, the development of commercial complex in our country is still in the initial stage lack of experience in the design and management field, due to the difference of economic, cultural, regional and other factors, the western city complex form can not be directly grafted to the local environment; thus, it is significant and urgent to explore the design method and development mode suitable for the complex building in our country and study on the commercial space of complex building.In this paper, the author analyze the status of urban commercial complex space through access to a large number of related books, documents, periodicals, on-the-spot investigation in Beijing, Tianjin, Shanghai, Jinan and other places, combining a large number of domestic and foreign cases. The paper firstly gives the definition and concept of urban complex and commercial space, then introduces commercial space of urban complex leads, and analyzes the spatial types and function formation. Subsequently, he analyzes the commercial space of city complex from two aspects, which respectively are the position and the tendency of commercial space of city complex. Finally he summarizes four types of design principles of modern city complex commercial space, and applies them to the design of a "spring flowing" -Jinan’s some ecological theme city complex commercial space.
