Objective: The paper is to analyze the progress of research on long-term care insurance pilots in China. Methods: 126 papers with the topic of "long-term insurance pilot" published from 2016 to 2021 were derived from the CNKI database. By using CiteSpace software, the knowledge map and time series map of key words were drawn to conduct visualized analysis on research content and focus. Results: The number of literature on long-term care insurance pilot has increased steadily, but there is little cooperation between authors. The contents of research could be classified into five groups, including the necessity and feasibility of long-term care insurance system, insurance benefit, care service, financing mechanism, pilot effect and related issues. The changes of research focus could be divided into three stages, including slow exploration period (2016), fast growth period (2017-2019) and steady growth period (2020-present). The design of long-term insurance system, financing method and the evaluation on the pilot effect are the research focus at present. Conclusion: The research on long-term care insurance pilot showed a periodic trend and were becoming more complicated. The further study should adopt innovative methodologies to strengthen the systematic research at national level.
