Many scholars have explored the structural characteristics of urban spatial interaction networks in China and have conducted spatio-temporal analyzes. However, scholars have mainly focused on the perspective of static networks and have not understood the dynamic spatial interaction patterns of Chinese cities. Therefore, this paper proposes a research framework to explore the urban dynamic spatial interaction patterns. Firstly, we establish a dynamic urban spatial interaction network according to monthly migration data. Then, the dynamic community detection algorithm, combined with the Louvain and Jaccard matching method, is used to obtain urban communities and their dynamic events. We construct event vectors for each urban community and use hierarchical clustering to cluster event vectors to obtain different types of spatial interaction patterns. Finally, we divide the urban dynamic interaction into three urban spatial interaction modes: fixed spatial interaction pattern, long-term spatial interaction pattern, and short-term spatial interaction pattern. According to the results, we find that the cities in well-developed areas (eastern China) and under-developed areas (northwestern China) mostly show fixed spatial interaction patterns and long-term spatial interaction patterns, while the cities in moderately developed areas (central and western China) often show short-term spatial interaction patterns. The research results and conclusions of this paper reveal the inter-monthly urban spatial interaction patterns in China, provide theoretical support for the policy making and development planning of urban agglomeration construction, and contribute to the coordinated development of national and regional cities.<\/jats:p>","DOI":"10.3390\/ijgi11090486","type":"journal-article","created":{"date-parts":[[2022,9,14]],"date-time":"2022-09-14T20:50:45Z","timestamp":1663188645000},"page":"486","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Exploring the Inter-Monthly Dynamic Patterns of Chinese Urban Spatial Interaction Networks Based on Baidu Migration Data"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2398-2815","authenticated-orcid":false,"given":"Heping","family":"Jiang","sequence":"first","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"Beijing Laboratory of Water Resources Security, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State Key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}]},{"given":"Shijia","family":"Luo","sequence":"additional","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"Beijing Laboratory of Water Resources Security, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State Key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}]},{"given":"Jiahui","family":"Qin","sequence":"additional","affiliation":[{"name":"School of Environment and Spatial Informatics, China University of Mining and Technology, Xuzhou 221116, China"}]},{"given":"Ruihua","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"Beijing Laboratory of Water Resources Security, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State Key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}]},{"given":"Disheng","family":"Yi","sequence":"additional","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"Beijing Laboratory of Water Resources Security, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State Key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8339-361X","authenticated-orcid":false,"given":"Yusi","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"Beijing Laboratory of Water Resources Security, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State Key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}]},{"given":"Jing","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"Beijing Laboratory of Water Resources Security, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State Key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,14]]},"reference":[{"key":"ref_1","unstructured":"Castells, M.
