基于2020年中国家庭追踪调查（CFPS）数据，利用OLS、工具变量法等分析了数字反哺对老年人健康水平的影响及其作用机制。结果表明：数字反哺对老年人的健康水平具有显著的正向效应。并且，这种影响具有显著的城乡、性别和年龄异质性。进一步研究发现，医疗服务利用在数字反哺与老年人健康水平的关系中起着中介作用。因此，不仅要发挥家庭数字反哺的作用，还要构建多主体协同的“数字反哺”模式，提升老年人数字技能。政府要提升数字资源配置均衡性，相关企业要“因人而异”，开发满足不同老年群体数字需求的适老化产品；同时发展适老型数字医疗服务，弥合数字就医鸿沟，提高老年人健康水平。

Based on the 2020 China Family Panel Studies(CFPS) data, this article employs methods such as Ordinary Least Squares(OLS) and instrumental variable analysis to explore the extent and mechanism of the impact of digital feedback on the health level of the elderly. The results indicate that digital feedback has a significant positive effect on the health levels of the elderly. Moreover, this impact exhibits notable heterogeneity across urban and rural areas, genders, and age groups. Further research reveals that the utilization of medical services plays a mediating role in the relationship between digital feedback and the health levels of the elderly. Therefore, it is essential not only to leverage the role of family-based digital feedback but also to establish a multi-agent collaborative "digital feedback" model to enhance the digital skills of the elderly. The government should improve the equitable distribution of digital resources, while relevant enterprises should adopt a "tailored approach" to develop age-friendly products that meet the digital needs of different elderly groups. Additionally, the development of age-appropriate digital medical services is crucial to bridge the digital healthcare gap for the elderly and improve their health levels.
