A questionnaire survey was conducted among 331 community-dwelling older adults, and multiple linear regression analysis was applied to identify factors influencing care service demands.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Key findings include: (1) Older adult\u2019 demands manifest a five-dimensional structure (life assistance, medical care, spiritual\/cultural engagement, rights protection, and age-friendly modifications), with spiritual\/cultural engagement (score rate: 68.40%) and age-friendly modifications (67.67%) being the most urgent needs. (2) Subgroups including advanced age (\u226571\u202fyears), disabled, living alone, highly educated, and chronic disease individuals exhibited significantly higher demand intensity (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.05). For instance, the regression coefficient (<jats:italic>B<\/jats:italic>) for medical care demand among the disabled reached 0.545. (3) Based on these results, a modular service framework was constructed, featuring five functionally independent core modules. A dynamic service package combination function was innovatively proposed, utilizing a module activation coefficient (<jats:italic>\u03b1<jats:sub>k,i<\/jats:sub><\/jats:italic>) and an module weighting factor (<jats:italic>\u03b2<jats:sub>k,i<\/jats:sub><\/jats:italic>) to achieve precise customization.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Centered on community residents\u2019 committees (CRCs) as coordination hubs, this model enables dynamic monitoring and optimization through the Demand-Service Matching Index (DSMI), offering an actionable solution to reconcile fragmented resources and heterogeneous demands, thereby supporting both older adults and their caregivers in regional older adult care
