Abstract

There have been very few studies done on measuring the influence of all prefecture‐level cities on a national scale due to the limited availability of public data, challenges in data collection, and insufficient data comprehensiveness. In this paper, we aim to fill this gap by investigating this problem in China. We first collected 692,859 news articles spanning one full year from the WeChat Official Accounts of 339 cities and Taiwan Province, which served as our study area and dataset. Then, we developed a city extractor module to reduce the ambiguity of place names and constructed a city interaction network. Then, we modeled the City Influence Index (CII) and the intensity of its influence. Finally, we proposed an analytical framework that examines the relationship between CII and Gross Domestic Product (GDP), compares it with the Global Cities Index, conducts influence analysis of cities at different levels, and more. The experimental results demonstrate that our analytical framework can effectively measure the influence of cities on a national scale and uncover the implicit relationships between cities. In doing so, our study offers a new perspective for measuring city influence. Code is available at: https://github.com/vczero/CII.
城市影响力网络:基于社交媒体的中国城市影响力挖掘与分析
由于公共数据的可获得性有限、数据收集面临挑战以及数据不够全面,在全国范围内衡量所有地级市影响力的研究很少。本文旨在填补这一空白,对中国的这一问题进行研究。首先,我们从 339 个城市和台湾省的微信官方账号中收集了 692 859 篇新闻报道,时间跨度长达一整年。然后,我们开发了一个城市提取模块,以减少地名的模糊性,并构建了一个城市互动网络。然后,我们对城市影响指数(CII)及其影响强度进行了建模。最后,我们提出了一个分析框架,研究 CII 与国内生产总值(GDP)之间的关系,将其与全球城市指数进行比较,并对不同级别的城市进行影响力分析等。实验结果表明,我们的分析框架可以有效衡量城市在全国范围内的影响力,并揭示城市之间的隐性关系。因此,我们的研究为衡量城市影响力提供了一个新的视角。代码见:https://github.com/vczero/CII。
