Abstract: In the context of actively implementing the national strategy of population aging and promoting the overall construction of digital China， allowing more older people to adapt to the transformed life and enjoy digital welfare， the issue of digital integration of older people is undoubtedly a key topic in the coming period. Based on the social support theory， this paper utilizes the CGSS2017 data to conduct a study to classify digital integration into three dimensions， namely cognitive， skillbased and applied digital integration， and to explore the influence of informal support on the digital integration of the elderly on this basis. The results show that informal support from oneself significantly and positively affects the cognitive digital integration of middleaged and highaged seniors， informal support from children significantly and negatively affects the skillbased digital integration of lowaged seniors， and informal support from peers significantly and positively affects the applicationbased digital integration of lowaged seniors. Based on this， we propose to deepen the supply of Internet resources， promote the ageing and accessibility transformation of online and offline digital products and services， emphasize the power of peer groups， and encourage digital feedback， with the aim of providing a close and efficient social support system for the digital integration of the elderly， and accelerating the overall construction of digital China.
