基于生产性服务业的长江三角洲城市网络

摘要/Abstract

摘要： 全球化进程中，城市网络的研究成为国内外学者关注的重要前沿。借鉴西方有关的研究工具，从城市网络的层级特征、网络模式、功能特征三个方面分析了长江三角洲地区的生产性服务业的城市网络发展特征。研究表明：基于生产性服务业的长三角城市网络具有显著的层级特征，与已有的城市等级体系特征并不完全一致，个别城市如昆山、义乌等城市承担了重要的网络联系中心的作用。同时，城市间的网络连接也呈现出明显的位序关系，三大核心节点城市（上海、南京、杭州）之间的联系形成了长三角地区城市间网络的最主要的联系。从影响范围来看，上海的网络指向性最强，涉及面也最广，但南京和杭州的影响不再仅仅局限于自身所在省份之内，扁平化发展的趋势愈发显著。网络联系的核心区域开始由传统的上海、南京、杭州、宁波所围合的“Z”字型区域向北部的南通、扬州以及南部的绍兴等地区扩散。根据不同类型的生产性服务业所形成的网络特征的不同，将11个部门分为完善型、扁平型、专业型等三种类型。

Abstract: In the process of globalization, urban network has become research frontier of domestic and foreign scholars. By using research tools of western academics, this article analyses urban network development characteristics of the Yangtze River Delta region based on producer services from three aspects, which are hierarchy structure, network mode and functional characteristics. Studies have shown that urban network of the Yangtze River Delta region based on producer services has a significant hierarchy structure, but not entirely in conformity with the existing urban hierarchy characteristics, in which cities like Kunshan and Yiwu play the role of important network center. Meanwhile, the network connection between cities also shows significant sequence relationship by importance, and the network of producer services between three core node cities(Shanghai, Nanjing and Hangzhou) forms the most important network links of the Yangtze River Delta region. From the influence sphere of the three core nodes, Shanghai network has the most remarkable directivity and is most widely covered, while that of Nanjing and Hangzhou is no longer merely confined to within their own province area. The development trend of flat structure is increasingly significant. The core area with a "Z"-shaped one by traditional Shanghai, Nanjing, Hangzhou and Ningbo has turned to spread to the northern region of Nantong, Yangzhou and southern part of Shaoxing and other regions. According to the different network characteristics formed by different types of producer services, 11 departments could be classified into three types:perfect type, flat type, and professional type. The network formed by banking and finance,insurance and IT functions reveals prominent hierarchy phenomenon, and develops a relatively complete network, so it is called the perfect type. Cities covered by real estate,securities, logistics functions has more functions, but its hierarchy phenomenon is not obvious, and the distribution of the functional center is more scattered, thus it is known as the flat type. The distribution of network function center formed by accounting, law, advertising,management consulting, design and service functions is more concentrated, at the same time,in addition to the function center, the service value of other node cities is very small,therefore it is called a professional network.

Key words: Yangtze River Delta region, producer services industry, urban network, network connectivity
