生产性服务业视角下城市网络的演化模式与机制研究——以长江三角洲为例

从行业属性、企业内部因素和城市所处的环境3个层面的耦合关系视角,对生产性服务业视角下城市网络的形成演化模式和演化机制进行了理论探索。在基于地理空间的行政等级体系基础上,考虑到生产性服务业发展对于城市网络的综合影响,归纳了由初始集聚阶段-非均衡扩散阶段-等级网络形成阶段-网络成熟阶段的生产性服务业视角下城市网络的一般演化模式。实证研究表明,长三角城市网络正处于非均衡扩散向等级网络阶段演化的过渡时期,表现出网络的层级特征愈发明显、水平联系不断增强、联系方向更加多样化、服务功能联系差距缩小等特征。联系便捷程度、创新要素支撑、制造业发展基础,以及城市能级推动等要素对于长三角城市网络的影响较大。

The Evolution Mode and Mechanism of Urban Network from the Perspective of Producer Services Industry: A Case of the Yangtze River Delta

This article makes a theoretical exploration on the formation and evolution mechanism of urban network based on producer services from the perspective of the recognition mechanism of urban network and the behavior mechanism of enterprise layout, specifically, including industry attributes, the internal factors of the enterprise and the urban environment. On the basis of the theory of regional development and industrial evolution, considering the process of enterprise spatial expansion, taking into account the geography-based administrative hierarchical system and the impact of producer services on urban network, the paper summarizes the general evolution model of the general evolution model of the initial agglomeration -unbalanced diffusion - hierarchical network - mature network of urban network based on producer service. At different stages, industrial space combinations, urban functional organization and urban hierarchy characteristics are constantly changing. The empirical study shows that the Yangtze River Delta urban network is in the transition period of unbalanced diffusion to the hierarchical network stage, showing that the obvious hierarchical characteristics, increasing horizontal linkages, contact direction showing the multiple trend, and the reduced service function contact gap. Its dynamic mechanism includes the convenience of contact, the foundation of manufacturing development, the support of innovation elements, and the promotion of city level. Under the combined action of these factors, the urban network structure of the Yangtze River Delta is becoming more and more perfect, and the horizontal link between the cities is increasing. The driving force of the formation and evolution of the urban network based on the productive service industry is not only derived from the location choice, the power distribution, the organizational structure of the enterprise, but also influenced by the government regulation. The future trend of the development of the network, whether there is a reasonable trend, and how does the government play a "positive intervention" role need to be further studied.
