Based on the panel data of 30 provinces from 2017 to 2022，this study measured the coupling coordination degree between traditional Chinese medicine services and elderly care services in China by applying the improved CRITIC entropy weight combination weighting method and the coupling coordination development model，while also further exploring the spatial connection，regional disparities，and dynamic evolutionary characteristics of the coupling coordination degree. The findings revealed that the coupling coordination degree between traditional Chinese medicine services and elderly care services was in the transitional and developmental stage from 2017 to 2022. The spatial linkage was continuously strengthened， showing significant spatial proximity and regional agglomeration effects. Regional disparities in the coupling coordination degree gradually decreased，primarily derived from the inter-regional differences. There were certain club convergence characteristics in the coupling coordination degree at both high and low level. Based on this，the study indicates that the coupling coordination level between traditional Chinese medicine services and elderly care services still needs improvement. Moving forward，it is essential to strengthen cross - regional cooperation， maximize the driving effect of spatial linkage，and narrow the regional gaps. Development measures should be formulated tailored to local conditions to promote the upward transitions in the coupling coordination degree.
