RESEARCH ON CHINA'S CITY NETWORK BASED ON PRODUCTION SERVICE INDUSTRY

Based on the concept of world city network(WCN),this paper analyzes the city network that is based on production service industry in mainland China from three levels.The corresponding findings include:firstly,at the subnodal level,the strategy of location choice focuses on setting up offices in core cities so as to maximize the profits instead of expanding hinterland to establish spatial monopolization as before;secondly,at the city node level,Beijing and Shanghai became the two dominant cities attracting the gathering of production service industry and the coastal city clusters are the primary areas with the concentration of production service industry while the majority of other cities are in the peripheral area of the network where the connection degree is comparatively low;thirdly,at the city network level,similar to the world city network,the dominant effects of Beijing and Shanghai in the city network are quite significant and the linkage among main cities,namely,Beijing,Shanghai,Guangzhou and Shenzhen in the three city clusters of mainland China forms the primary network of the production service industry in the country.
