The factors that influence PM2.5 in different regions exhibit significant spatial heterogeneity. Current research has quantified the spatial heterogeneity of single factors but fails to discuss the interactions between factors. In this study, we first divided the study area into subregions based on the spatial heterogeneity of factors in a multi-scale geographically weighted regression model. We then investigated the interactions between different factors in the subregions using the geographical detector model. The results indicate that there was significant spatial heterogeneity in the interactions between the driving factors of PM2.5. The interactions between natural factors have significant uncertainty, as do those between the normalized difference vegetation index (NDVI) and socioeconomic factors. The interactions between socioeconomic factors in the subregions were consistent with those in the whole region. Our findings are expected to deepen the understanding of the mechanisms at play among the aforementioned drivers and aid policymakers in adopting unique governance strategies across different regions.<\/jats:p>","DOI":"10.3390\/rs13245079","type":"journal-article","created":{"date-parts":[[2021,12,14]],"date-time":"2021-12-14T22:06:10Z","timestamp":1639519570000},"page":"5079","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Assessing Spatial Heterogeneity of Factor Interactions on PM2.5 Concentrations in Chinese Cities"],"prefix":"10.3390","volume":"13","author":[{"given":"Yuhao","family":"Jin","sequence":"first","affiliation":[{"name":"College of Water Conservancy and Civil Engineering, South China Agricultural University, Guangzhou 510642, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9251-5452","authenticated-orcid":false,"given":"Han","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Lab of Geographic Information Science of the Ministry of Education, School of Geographic Sciences, East China Normal University, Shanghai 200241, China"}]},{"given":"Hong","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Tourism and Historical Culture, Southwest Minzu University, Chengdu 610041, China"}]},{"given":"Huilin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Water Conservancy and Civil Engineering, South China Agricultural University, Guangzhou 510642, China"}]},{"given":"Zhenfeng","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Economic and Trade, Guangxi University of Finance and Economics, Nanning 530007, China"}]},{"given":"Yuxing","family":"Han","sequence":"additional","affiliation":[{"name":"College of Electronic Engineering, South China Agricultural University, Guangzhou 510642, China"}]},{"given":"Peitong","family":"Cong","sequence":"additional","affiliation":[{"name":"College of Water Conservancy and Civil Engineering, South China Agricultural University, Guangzhou 510642, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"367","DOI":"10.1038\/nature15371","article-title":"The contribution of outdoor air pollution sources to premature mortality on a global scale","volume":"525","author":"Lelieveld","year":"2015","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1179","DOI":"10.1038\/4351179a","article-title":"China\u2019s environment in a globalizing world","volume":"435","author":"Liu","year":"2005","journal-title":"Nature"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1701","DOI":"10.1016\/j.proenv.2010.10.181","article-title":"Environmental Policies in China over the Past 10 Years: Progress, Problems and Prospects","volume":"2","author":"Wang","year":"2010","journal-title":"Procedia Environ.
