中国互联网企业空间演化与城市网络特征研究

SPATIAL EVOLUTION OF CHINA'S INTERNET ENTERPRISES AND THE CHARACTERISTICS OF CITY NETWORK

高速发展的信息网络技术使得时空压缩,信息流、资金流、人流等要素流正在潜移默化地重塑着城市体系。互联网企业及其与实体行业的相互渗透使得它们成为信息时代各种要素流动的综合体现。本文借鉴Taylor等提出的基于高级生产性服务业的世界城市网络研究方法,以中国百强互联网企业总部及分支机构数据为基础,引入社会网络分析、空间统计分析等方法,从企业演化的角度分析互联网企业空间格局与城市网络特性。从2000、2005、2010和2017年互联网企业空间分布、规模与等级分布、"互联网+"/纯互联网企业分布及它们的演化规律分析互联网企业空间格局。研究发现全国层面的互联网企业空间分布极化,城市网络中心性与扁平化并存,网络整体地域性减弱。

In the Information Age, the rapid development of information network technology leads to the phenomenon of space-time compression. Flow of information, flow of capital, flow of people and other flows are reshaping the city system, making city system networked. Differ from researches based on advanced producer services, this paper focus on Internet enterprises, which can be seen as comprehensive expression of the various flows of the Information Age, for the informationization characteristics of internet interprise and its mutual penetration with the entity industry. This paper draws on the research methods of the world city network, which is based on advanced producer services, proposed by Taylor and his collaborators. This pa- per analyzes the spatial pattern of Internet enterprises and characteristics of China city network, based on the social network analysis and spatial statistical analysis, and the data of China＇s top 100 Internet enterprises headquarters and branches. Analysising spatial distribution pattern of Internet enterprises from mutiple per- spectives, such as the spatial distribution of Internet enterprises in 2000, 2005, 2010 and 2017, the distribution of its scale and rank, the distribution of ＂Internet ＋＂ and pure Internet enterprises, etc. According to its scale and grade, the city associated network is constructed, so as to prove the characteristics of the multi-center pattern, centrality, flatness and locality of China city network. It is found that there is a spatial distribution polarization of Internet enterprises at the national level, and coexistence of centrality and flatness of city net-work, and weakening of network locality.
