This paper selects tertiary grade A hospitals, general hospitals, specialized hospitals, community-level hospitals, clinics, and pharmacies in the main urban areas of Chongqing as research objects. The nearest analysis, kernel density, mean center, and standard deviational ellipse method were used to analyze the spatial differentiation characteristics of medical facilities and public transportation stations. Spatial accessibility was assessed from the perspective of service area ratios and service population ratios by constructing multiple modes of transportation (pedestrian systems, bus lines, rail lines). The results show that (1) the spatial layout of medical facilities in the main urban area of Chongqing is unbalanced; and the spatial distribution of medical facilities is characterized by \u201clarge agglomeration, small dispersion\u201d and \u201cmulti-center group\u201d; (2) the sub-core circle is centered on the Southwest University Area in Beibei District, the University Town Area in Shapingba, the Yudong Area and Lijiatuo Area in Banan District, the Pingan Light Rail Station Area in Dadukou District, the Chongqing No. 8 Middle School Area in Jiulongpo District, the Tea Garden Area in Nanan District, and the Jiangbei Airport Area in Yubei District; (3) the medical facilities with the weakest average accessibility are tertiary grade A hospitals, and the strongest are pharmacies; (4) the areas with vital average accessibility are Yuzhong District, Shapingba District, Dadukou District, and Nanan District.<\/jats:p>","DOI":"10.3390\/ijerph192316224","type":"journal-article","created":{"date-parts":[[2022,12,5]],"date-time":"2022-12-05T02:56:26Z","timestamp":1670208986000},"page":"16224","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Spatial Accessibility Analysis of Medical Facilities Based on Public Transportation Networks"],"prefix":"10.3390","volume":"19","author":[{"given":"Ying","family":"Liu","sequence":"first","affiliation":[{"name":"College of Architecture and Urban Planning, Chongqing Jiaotong University, Chongqing 400075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han","family":"Gu","sequence":"additional","affiliation":[{"name":"College of Architecture and Urban Planning, Chongqing Jiaotong University, Chongqing 400075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuyu","family":"Shi","sequence":"additional","affiliation":[{"name":"College of Architecture and Urban Planning, Chongqing Jiaotong University, Chongqing 400075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"54","DOI":"10.1080\/00330120701724087","article-title":"Late-Stage Breast Cancer Diagnosis and Healthcare Access in Illinois","volume":"60","author":"Wang","year":"2008","journal-title":"Prof. Geogr."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"909","DOI":"10.1002\/cncr.23229","article-title":"Geographic Access to Cancer Care in the U.S","volume":"112","author":"Onega","year":"2008","journal-title":"Cancer"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"102869","DOI":"10.1016\/j.jtrangeo.2020.102869","article-title":"Transit Deserts: Equity Analysis of Public Transit Accessibility\u2014ScienceDirect","volume":"89","year":"2020","journal-title":"J.
