biostudies-literatureUnknown10Zhang L<h4>Objective</h4>The aging population in China highlights the significance of long-term care insurance (LTCI). This study provides policy suggestions for China to establish a sustainable LTCI financing mechanism by predicting the trend of funds balance and screening the appropriate financing scheme.<h4>Method</h4>A system dynamics model (SDM) of LTCI funds was constructed by clarifying the current situation and its main influencing factors of revenue and expenditure of LTCI funds in China. Also, through literature research and expert consultation, we found the intervention goals and predicted the changing trend of LTCI fund balance from 2020 to 2050 under different intervention schemes.<h4>Results</h4>The SDM of LTCI financing passes the dimensional consistency test, structural test, and Frontiers in public health908864https://www.ebi.ac.uk/biostudies/studies/S-EPMC9538358biostudies-literatureResearch on the optimization of financing scheme of long-term care insurance in China based on system dynamics simulation.PMC9538358Fang YFu SZhang LWang YfalseResearch on the optimization of financing scheme of long-term care insurance in China based on system dynamics simulation.<h4>Objective</h4>The aging population in China highlights the significance of long-term care insurance (LTCI).
