Public Health"],"abstract":"<jats:p>The services that are not covered by the long-term care insurance play a critical role in supplementing the public care system in the aging society of Japan. Their combination with technologies of the shared economy is not only an extension of the shared economy into the specialized service market, but it is also a natural demand of the market in the long-term care service market that is the necessity to innovate and develop. This study constructed a technology acceptance extension model, using the Tokyo area as the survey scope. 486 valid samples were collected through a questionnaire survey, and partial least squares structural equation modeling was used to conduct hypothesis testing and empirically analyze the acceptance behavior of the older adult towards shared service platforms outside of long-term care insurance. The main findings are: (1) Scene characteristics may have a reshaping effect on the local behavior of the older adult in technology acceptance. (2) The single cognitive load of new technology in old scenes and the dual cognitive load of new technology in new scenes may be key to whether the older adult technology acceptance behavior undergoes local reshaping. (3) The \u201cfirst principle\u201d of perceived ease of use in the cognitive logic of the older adult group is emphasized. (4) The \u201cexternal social construction\u201d of perceived usefulness and the \u201cendogenous individual defense\u201d of perceived risk may be the unique cognitive logic of acceptance behavior in such scenarios.<\/jats:p>","DOI":"10.3389\/fpubh.2026.1847810","type":"journal-article","created":{"date-parts":[[2026,7,23]],"date-time":"2026-07-23T04:32:14Z","timestamp":1784781134000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Older adults\u2019 adoption of shared service platforms outside long-term care insurance in Japan based on technology acceptance model"],"prefix":"10.3389","volume":"14","author":[{"given":"Chao","family":"Li","sequence":"first","affiliation":[{"name":"School of Business, Guilin University of Technology","place":["Guilin, China"]},{"name":"School of Social Welfare, Tokyo University of Social Welfare","place":["Tokyo, Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunji","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Social Welfare, Tokyo University of Social Welfare","place":["Tokyo, Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziheng","family":"Lv","sequence":"additional","affiliation":[{"name":"School of Social Welfare, Tokyo University of Social Welfare","place":["Tokyo, Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,23]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"103158","DOI":"10.1016\/j.omega.2024.103158","article-title":"Sharing service in healthcare systems: a recent survey","volume":"129","author":"Wang","year":"2024","journal-title":"OMEGA Int J Manag Sci"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"102470","DOI":"10.1016\/j.ijhm.2020.102470","article-title":"Sharing economy: a comprehensive literature review","volume":"87","author":"Hossain","year":"2020","journal-title":"Int J Hosp Manag"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"97","DOI":"10.1007\/s11365-017-0460-9","article-title":"Entrepreneurship for long-term care in sharing economy","volume":"14","author":"Huarng","year":"2018","journal-title":"Int Entrep Manag J"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"3115","DOI":"10.1080\/13683500.2020.1786505","article-title":"Peer-to-peer (P2P) accommodation in the sharing economy: a review","volume":"25","author":"Kuhzady","year":"2022","journal-title":"Curr Issues Tour"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"1711","DOI":"10.1108\/ijchm-12-2020-1457","article-title":"Sharing economy research in hospitality and tourism: a critical review using bibliometric analysis, content analysis and a quantitative systematic literature review","volume":"33","author":"Mody","year":"2021","journal-title":"Int J Contemp Hosp Manag"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"688","DOI":"10.1080\/02681102.2022.2068492","article-title":"Digital inequality beyond the digital divide: conceptualizing adverse digital incorporation in the global south","volume":"28","author":"Heeks","year":"2022","journal-title":"Inf Technol Dev"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"96","DOI":"10.35784\/preko.6691","article-title":"Digital inequality and sustainable development","volume":"20","author":"Rydzewski","year":"2025","journal-title":"Probl Ekorozwoju"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"103223","DOI":"10.1016\/j.healthplace.2024.103223","article-title":"Does the neighborhood built and social environment reduce long-term care costs for Japanese older people?
