This study utilizes data from the 2018 China Longitudinal Ageing Social Survey to evaluate the current situa-tion of these renovations by considering regional and group differ-ences,specifically focusing on environmental renovations and device configurations.Drawing on the International Classification of Functioning,Disability,and Health(ICF)framework pro-posed by the World Health Organization,this study investigates the effects of home-based aging-adaptation renovations on ol-der adults'life satisfaction,with a particular emphasis putting on exploring the mediating effects of emotion,cognition,and so-cial functions in these relationships.Additionally,the study ex-amines whether there are urban-rural differences in terms of these mediating effects.The results indicate that home-based aging-adaptation renovations have significantly positive impacts on older adults'life satisfaction.Emotion,cognition,and social functions play multiple mediating roles in these relationships,af-ter controlling for the effect of activity function.Moreover,urban-rural differences are observed in terms of these mediating effects.Considering the positive effects of home-based aging-adaptation on older adults'functional abilities,it is crucial to target the effective supply of basic elderly care services towards older adults with functional limitations.Importantly,an integrat-ed functional assessment that encompasses activity,emotion,cognition,and social functions should serve as the foundation for delivering basic elderly care services.
