Abstract: China is experiencing rapid population ageing and witnesses a wide spread of information technology. The rise of novel internet technologies may increasingly influence older adults' daily life. Using data from a survey on midage and older adults' short video application use conducted in 2021, this study investigates the relationships between short video app usage and midage and older adults' social networks, commutation with family members and friends, social inclusion and mental health. Results show that the moderate use of short video app increases midage and older adults' communication with families and friends, expands their social networks, and promotes their social inclusion. We should also acknowledge that older people face many problems and risks in the digital era. Findings suggest that collective efforts should be made by government, corporations, local communities as well as families to mitigate agerelated digital divide.

摘要： 在人口老龄化快速推进和信息技术迅速普及的背景下，研究互联网新技术、新现象如何影响老年人的生活是积极老龄化的重要议题。利用2021年中老年人短视频应用使用情况专项调查数据，从中老年人的家庭关系、朋友关系、社会适应、心理健康4个方面入手,重点分析近年来兴起的短视频应用对中老年人生活的影响。研究发现，短视频应用的适当使用在一定程度上加强了中老年人与家人和朋友的联系及互动，扩大了中老年人的社会网络，也提高了中老年人的社会适应水平。与此同时，应该重视互联网时代中老年人面临的问题和风险。建议政府、企业、社区和家庭共同参与，助力中老年人跨越数字鸿沟，使中老年人充分享受数字红利。
