Twenty Years of Digital Media Use Research on China's Silver Hair Group (2005-2024) : A CiteSpace-based Knowledge Graph Analysis

China's population over 60 years old has accounted for 21.1% of the total population, and the topic of digital media use among the silver-haired group has witnessed unprecedented academic discussions, which makes it more and more necessary to comprehensively sort out the academic lineage of this topic. Using 2,293 articles in the China Knowledge Network database from 2005 to 2024 as the data source, and based on CiteSpace software, this study draws a knowledge map in terms of publication trend, keyword co-occurrence, keyword clustering, and the evolution of the research lineage, and finds that over the past two decades, research on the use of digital media by the silver-haired group in China has mainly focused on the barriers to digital integration and social adaptation, the smart elderly service system and social adaptation, and the digital media use of the silver-haired group. It is found that over the past two decades, research on the digital media use of the silver-haired population in China has mainly focused on the digital integration barriers and social adaptation of the silver-haired population, the smart elderly service system and the silver-haired economy, and health communication. This study suggests that in the future, research on the digital media use of the silver-haired population may need to focus on deepening the two-way mutual support mechanism between the new quality of productivity and the silver-haired economy, constructing a localised explanatory framework, and strengthening the practical orientation of technological ethics and ageing-friendly design.
