This study aims to explore the convergence technology and support policies of China's smart elderly care according to the development of ICT over the past 15 years and to derive future research topics and directions. CNKI, a Chinese DB platform, collected 6,346 academic papers related to smart elderly care under the condition that they included ‘Smart’ and ‘Elderly care’ in the abstract. The keywords collected from these papers were refined, resulting in 1,970 keywords for Period 1, 3,707 for Period 2, and 4,831 for Period 3. Among them, 44, 60, and 69 keywords were ultimately used for analysis. The results of the analysis using UCINET software are as follows. First, in terms of technology application, research on ‘AI’, ‘Robots’ and 'Metaverse’ will be actively conducted over the next five years, supported by policy guidelines. In particular, case studies on elderly care robots will be added. Second, in terms of policy support, the government-led fostering of the ‘Silver economy’ and ‘Smart elderly care’ is an approach to solving the aging society through technology, which will secure technological competitiveness in the global market in the future. Third, in terms of core topics, it is necessary to pay attention to the ‘Time Bank’ and ‘Virtual Elderly Care Facility’ platform. These are sustainable models centered on smart home care that can solve social problems such as high Elderly care costs, Elderly care burden, and lack of Elderly care resources.
