It investigates these issues within the Guangdong\u2013Hong Kong\u2013Macao Greater Bay Area (GBA), utilizing point-of-interest (POI) data, spatial kernel density, the HDBSCAN clustering algorithm, and colocation quotients. The findings are as follows: (1) this research reveals a significant spatial agglomeration of food services near the Pearl River, with notable food clusters across administrative boundaries; (2) Guangzhou, Shenzhen, Foshan, and Dongguan provide a significant quantity of food services, while Hong Kong and Macao feature the highest percentages of foreign cuisine; (3) the colocation between food services and surrounding services is concentrated along the Pearl River; (4) leisure, education, and residential services are key factors attracting the proximity of food services; (5) leisure, education, retail, and tourism services exhibit the strongest attractiveness to Chinese food, while residential and healthcare services are closely linked to the distribution of snacks, and transportation services attract snacks and beverages.<\/jats:p>","DOI":"10.3390\/ijgi14020040","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T08:46:26Z","timestamp":1737449186000},"page":"40","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Agglomeration of Food Services and Their Colocation with Surrounding Complementary Services in the Guangdong\u2013Hong Kong\u2013Macao Greater Bay Area"],"prefix":"10.3390","volume":"14","author":[{"given":"Yixiao","family":"Wang","sequence":"first","affiliation":[{"name":"Guangzhou Academy of Social Sciences, Guangzhou 510410, China"}]},{"given":"Xibo","family":"Wu","sequence":"additional","affiliation":[{"name":"Guangzhou Academy of Social Sciences, Guangzhou 510410, China"}]},{"given":"Jian","family":"Qin","sequence":"additional","affiliation":[{"name":"Guangzhou Academy of Social Sciences, Guangzhou 510410, China"}]},{"given":"Xiaoying","family":"Zhang","sequence":"additional","affiliation":[{"name":"Guangzhou Academy of Social Sciences, Guangzhou 510410, China"}]},{"given":"Xiangyu","family":"Wang","sequence":"additional","affiliation":[{"name":"Guangzhou Academy of Social Sciences, Guangzhou 510410, China"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1093\/jeg\/1.1.27","article-title":"Consumer city","volume":"1","author":"Glaeser","year":"2001","journal-title":"J.
