Through the summary and analysis of the research hotspots of aging design in recent twenty years in China, This paper provides ideas and guidance for improving the design strategy for aging users, and implement and promote design research for aging users to really solve the problems brought by the aging population.Using Cite Space software and CNKI quantitative tools, this paper summarizes the hot topics, evolution trends and authors of the design research for aging users in China by using bibliometrics method.Policy system is the main driving force of design research for aging user, social benefits are greater than economic benefits, but design research and application are slightly insufficient. University scholars are the main body of research, but the cooperation and communication between institutions and authors need to be further strengthened. The relevant theoretical research has realized the transformation from the universal method to the target user, but the design theory has not been studied and promoted, and the translation and popularization of design specifications still need to be strengthened. Practical research has gradually shifted from humanistic perspective to mathematical and chemical thinking, and is committed to the accurate algorithm design for complex elderly user groups, which is a new construction of design thinking and methodology. The design research for aging user has gradually changed from the early functional explicit improvement to the logical implicit optimization, and the themes of intelligence, medical care, service, urban elderly, and vulnerable groups of the elderly have become the focus of sustainable research.
