Based on the theory of integrated technology acceptance model(UTAUT), the willingness of home-based elderly people and its influencing factors was explored to adopt the smart elderly care platform. A questionnaire was designed. SPSS and Amos were used to model structural equation. The results are as follows: performance expectation, endeavor expectation ,community perception and cooperation level, all have significant effects on the adoption intention of the elderly platform, and the adoption intention will significantly stimulate the adoption behavior. Then the conclusion is that the smart platform for the aged will improve the cognition of the platform through multichannel social promotion. Platform operators should fully collaborate with communities, businesses, and families to form a smart elderly care service atmosphere. At the same time, targeted services are recommended based on the specific needs of the elderly, promoting their recognition of the platform's value and improving their willingness to adopt.
