基于生产性服务业的中国城市网络研究

借鉴世界城市网络(WCN)的概念框架,从三个层面分析了中国大陆地区生产性服务业的城市网络体系。基于中国城市网络(CCN)的计算结果,研究认为:生产性服务业企业的区位竞争不再仅依赖于线性地拓展腹地赢取空间垄断地位,而是以网络化的布局模式在核心城市设立分支机构以实现利润的最大化;在城市节点层面,上海、北京成为主要的生产性服务业集聚城市,沿海的城市群则成为生产性服务业的主要集聚区域,内地的大部分城市处于生产性服务业链接程度相对较低的外围;在城市网络层面,城市之间关联网络中的首位效应(北京—上海的关联)非常明显,三大城市群中核心城市(北京、上海、广州、深圳)之间的网络构成了中国大陆地区生产性服务业的核心链接。

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.
