In this paper, the quantities of relevant media articles in WeChat and Weibo between cities are taken as the traffic indices to construct a directional and weighted urban network of the Chengdu-Chongqing Economic Circle in China. Based on this network construction method, which adds direction thinking, we analyze the characteristics of information interconnection between cities. According to the analysis, we find that the provincial boundary hinders information interconnection, and the imbalance of external information interconnection is more serious in Chongqing\u2019s central urban area, Liangping, Ya\u2019an and Mianyang. In addition, we analyze the centrality status of different cities in the outward and inward perspective and further explore the factors that cause these differences in centrality. The results show that the centrality of the information network is not sensitive to the basic strength of the city, and it is the accessibility, including high-speed rail transportation access and telecommunication access, which controls the centrality of the city network.<\/jats:p>","DOI":"10.3390\/ijgi12010001","type":"journal-article","created":{"date-parts":[[2022,12,20]],"date-time":"2022-12-20T04:45:53Z","timestamp":1671511553000},"page":"1","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Directional and Weighted Urban Network Analysis in the Chengdu-Chongqing Economic Circle from the Perspective of New Media Information Flow"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5991-1675","authenticated-orcid":false,"given":"Changwei","family":"Xiao","sequence":"first","affiliation":[{"name":"School of Geography and Tourism, Chongqing Normal University, 37 Daxuechengzhong Road, Shapingba District, Chongqing 401331, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunxia","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Geography and Tourism, Chongqing Normal University, 37 Daxuechengzhong Road, Shapingba District, Chongqing 401331, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9263-7599","authenticated-orcid":false,"given":"Yuechen","family":"Li","sequence":"additional","affiliation":[{"name":"Chongqing Jinfo Mountain Karst Ecosystem National Observation and Research Station, Chongqing Engineering Research Center for Remote Sensing Big Data Application, School of Geographical Sciences, Southwest University, Chongqing 400715, China"},{"name":"Key Laboratory of Monitoring, Evaluation and Early Warning of Territorial Spatial Planning Implementation, Ministry of Natural Resources, Chongqing 401147, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"103005","DOI":"10.1016\/j.cities.2020.103005","article-title":"The evolutionary mechanism of China\u2019s urban network from 1997 to 2015: An analysis of air passenger flows","volume":"109","author":"Zhang","year":"2021","journal-title":"Cities"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2297","DOI":"10.1068\/a38372","article-title":"Global Cities in the Global Corporate Network","volume":"39","author":"Carroll","year":"2007","journal-title":"Environ.
