Purpose/Significance To analyze the willingness and the influencing factors of the elderly to use internet hospitals , so as to promote the development of internet hospitals. Method/Process Based on the unified theory of acceptance and use of technology 2 (UTAUT2) model, a theoretical model and hypotheses are constructed, and a survey questionnaire is designed. Data are collected by the cross-sectional survey method. The software SPSS 27.0 and AMOS 28.0 are used to analyze the willingness of the elderly to use internet hospitals and the factors influencing their decision. Result/Conclusion The usage rate of core medical services in internet hospitals for the elderly is relatively low. Performance expectancy, effort expectancy, facilitating conditions, and self-efficacy positively influence the willingness to use, while perceived risk, technology anxiety, and resistance to change negatively influence the willingness to use. Price value have no significant impact on the willingness to use. It is recommended to strengthen offline training and guidance to enhance the self-efficacy of the elderly group, intensify aging-friendly transformation to reduce technical barriers, and lower perceived risks to improve safety protection.
