人流联系和经济联系视角下区域城市关联比较——基于手机信令数据和企业关联数据的研究

THE COMPARISON OF REGIONAL URBAN RELATIONS BETWEEN PEOPLE FLOW AND CAPITAL FLOW——A STUDY BASED ON MOBILE PHONE SIGNALING DATAAND FIRM INTERLOCK DATA

手机信令数据所代表的人流联系与国内外研究常用的企业关联数据在测度城市关联存在何种差异,尚缺乏明确的研究。本文以江西省北部地区为研究对象,分别以手机信令数据、企业关联数据测度城市关联,比较了两种城市关联与城市之间空间距离、人口规模的关系,比较了两种城市关联网络的层级、结构、腹地。主要研究发现:人流联系不仅集中在城市周边地区,而且集中于较高等级城市之间;经济联系则主要集中在较高等级城市之间。人流联系、经济联系受到城市人口规模影响均较小。人流联系显著地符合幂函数空间衰减规律。手机信令数据和企业关联数据是两种不同的城市关联数据,但可互为补充,较为全面地反映城市关联。

The purpose of this study is to explore the differences between people flow and capital flow by us- ing mobile phone signaling data and firm interlocking data to measure urban relations between cities in the northern region of Jiangxi Province. Based on the mobile signaling data, it is possible to identify the mobile phone users＇ home residence and their travel destinations. Our main conclusions are as follows： firstly, peo- ple flow and capital flow is obviously different relational data in urban system. Secondly, urban population size has small influence both on people flow and capital flow, but the spatial decay of people flow signifi- cantly meets the power function law, which is consistent with traditional gravity model. Thirdly, in people flow perspectives, the urban interlock network shows a massive group structure, while in capital flow perspectives, the urban interlock network presents a relatively scattered band structure. Fourthly, the people flow is more similar to the hypothesis of central theory, the capital flow has not formed a completely urban network system. Finally, the empirical result shows that the central place system is still prevalent and the urban network system has not yet formed in the northern region of Jiangxi Province, but the strict urban hierarchy system has been disintegrated.
