In the context of intelligent elderly care services, this paper focuses on the elderly population living alone, aiming to explore their willingness to participate in smart community home-based elderly care services and its influencing factors. Through multiple linear regression analysis of questionnaire survey data from 302 elderly people living alone in Nanchang City, Jiangxi Province, it was found that the level of awareness of smart elderly care services, encouragement from family and friends, and the ability to use them are the main factors affecting the willingness of elderly people living alone to participate. Based on this, the article proposes suggestions such as enhancing the promotion of smart elderly care services, optimizing the technical training system, and increasing financial support, in order to increase the participation of elderly people living alone and promote the optimization and implementation of the smart community home-based elderly care service model.
