Abstract: The aging of the population is an inevitable trend and a worldwide problem for the development of the global population,
and it is also the new normal of China's economic and social development. An in- depth analysis of the frontier hotspots and
development trends of the domestic population aging research can provide reference and guidance for further research in the academic community. High frequency words, co-occurrence words, co-citation clustering maps and emergent words were analyzed using the knowledge mapping software for the literature collected in the CSSCI index database for the recent 20 years. The study found that domestic aging research focuses on the process and causes of aging, the social services of aging, the relationship between aging and economic and social development, and the coping strategies of aging, and the aging of medical care, legal protection, and society research on participation and other aspects is relatively weak. The current themes of domestic aging research are home based care,economic growth, intergenerational relationships and well- being; and the ageing pension service and coping strategies are at the forefront of current domestic aging research. Future research should be based on diversified research content and methods to increasecross-research and innovative research on the aging of the domestic population in different disciplines and fields.
