Compared to the city network (or the network of urban areas), however, fewer studies focus on the network connecting rural areas or on the comparison of regional structures between urban and rural networks. Using weighted daily mobility flows from the massive mobile-phone signaling data, this study constructs an urban\u2013urban mobility (UUM) network and an urban\u2013rural mobility (URM) network in the Pearl River Delta (PRD) region. A weighted stochastic block model (WSBM) was adopted to identify and compare the latent mesoscale structures in the two networks. Results investigated a gradient community mesoscale structure nested with typical core\u2013periphery (CP) structures in the UUM network and an asymmetric bipartite mesoscale structure mixed with CP hierarchies in the URM network. In a comparison of the different spatial configuration of urban\/rural nodes and groupings of their roles, positions, and linkages, the study yielded empirical insights for renewed urban\u2013rural interaction and potential planning pathways towards urban\u2013rural integration.<\/jats:p>","DOI":"10.3390\/ijgi12050183","type":"journal-article","created":{"date-parts":[[2023,4,27]],"date-time":"2023-04-27T02:50:00Z","timestamp":1682563800000},"page":"183","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Mesoscale Structure in Urban\u2013Rural Mobility Networks in the Pearl River Delta Area: A Weighted Stochastic Block Modeling Analysis"],"prefix":"10.3390","volume":"12","author":[{"given":"Yurun","family":"Wang","sequence":"first","affiliation":[{"name":"School of Urban Planning & Design, Peking University Shenzhen Graduate School, Shenzhen 518055, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pu","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Urban Planning & Design, Peking University Shenzhen Graduate School, Shenzhen 518055, China"},{"name":"Shanghai Municipal Development & Reform Commission, Shanghai 200003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Senkai","family":"Xie","sequence":"additional","affiliation":[{"name":"Urban Planning and Transportation Group, Eindhoven University of Technology, 5600 MB Eindhoven, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7211-4205","authenticated-orcid":false,"given":"Wenjia","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Urban Planning & Design, Peking University Shenzhen Graduate School, Shenzhen 518055, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1038\/548275a","article-title":"Revitalize the World\u2019s Countryside","volume":"548","author":"Liu","year":"2017","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"186","DOI":"10.1177\/20438206221075818","article-title":"Geographies of Ruralization","volume":"12","author":"Gillen","year":"2022","journal-title":"Dialogues Hum.
