["Population, Space and Place, Volume 32, Issue 5, July 2026. ", "\nABSTRACT\nThis study examines how healthcare‐seeking preferences are associated with local embeddedness among Hong Kong residents in Guangzhou, a core city of the Guangdong–Hong Kong–Macao Greater Bay Area. While migration scholarship has extensively examined rural‐to‐urban migrants and international migrants, less attention has been paid to intra‐national but cross‐system mobility under One Country, Two Systems. Drawing on a questionnaire survey of 501 Hong Kong residents and cellphone‐based spatial information used to guide sampling, the study adopts a regression‐based path‐modelling strategy to examine conditional associations among healthcare preference, cross‐border attachment, local anchoring, and embeddedness‐related outcomes. Healthcare‐seeking preference is measured by whether respondents usually seek care in Guangzhou or rely on Hong Kong‐oriented arrangements, such as returning to Hong Kong hospitals or contacting Hong Kong family doctors. Local embeddedness is measured through contact with Mainland friends, sense of belonging to Guangzhou, and long‐term settlement intention in Mainland China. Results show that 19.2% of respondents reported Hong Kong‐oriented healthcare preferences. Such preferences are associated with stronger cross‐border attachment and weaker relational/place‐based local embeddedness, while local anchoring is associated with lower reliance on Hong Kong‐oriented care. These findings do not establish causality but highlight healthcare as an everyday site where cross‐border attachment and local embeddedness intersect.\n"]
