A research on commercial suburbanization in Beijing under the background of urban function dissemination
功能疏解背景下北京商业郊区化研究

Compared with the population suburbanization,scholars pay less attention to commercial suburbanization in China.Based on the data of retail sales of social consumer goods,the distribution of supermarkets,and leased commercial land lots,the paper describes the characteristics and driving mechanism of commercial suburbanization in Beijing.It states that commercial suburbanization developed rapidly in the inner suburb districts from 1991 to 2000,and since 2001,there has been a tendency of outer suburbs spread.The paper further illustrates that stores and leased commercial land lots mainly diffuse along the ring roads and radial roads from the urban center of Beijing.Besides the traditional commercial center,sub-centers and shopping malls have risen in the suburbs in recent years.As each quadrant has local conditions,there are significant differences of commercial suburbanization in different quadrants.In the northwest of the city,leased commercial land lots diffuse the fastest and expand the farthest.It is on the contrary in the southeast.The annual expansion rate of the lots fluctuates dramatically in the northeast and southwest.In the northeast,commercial development is more complex,due to the fact that besides the trends of suburbanization,there are centralized development patterns,mainly including urban renovation projects in the old town.Finally,the paper discusses four driving factors of commercial suburbanization,including the attraction of population and housing suburbanization,the promotion of rapid development of road transportation and private cars,the extrusion force from the urban center,and the guidance of government plans and policies.
