In this paper, the elderly people over 60 years old in Beijing who use WeChat Moments as the research object, using the integrated technology acceptance and use theoretical model (UTAUT) as the theoretical framework, through the structural equation model to analyze the willingness and behavior of the elderly people to use WeChat Moments. The research found that the two potential variables that affect the use behavior of WeChat Moments are the use of WeChat Among the potential variables that affect the use intention, the two potential variables with the highest total effect are the social and economic status and community in?uence of the offspring, while the risk perception and the use intention have negative effects. Among the potential variables that affect the use behavior, the use intention, the social and economic status of the offspring and the digital feedback intention are the potential variables with the highest effect. On this basis, this paper extends and constructed a new technology using UTAUT model for the elderly.
