Objective Based on the health level,the factors affecting female labor participation were understood,and the years of delayed employment for middle-aged and elderly women were estimated.Methods Using the 2011,2013,2015,and 2018(CHARLS)data,Women aged 45～69 years were selected as subjects.The CMR health measurement model was used to estimate the delayed working years of women with different characteristics.Results The average labor force participation rate for women aged 45～69 is 66.93%,with the poorer the level of health,the more likely they are to drop out of the labor market.women aged 50～69 have an additional working capacity of 3.29～3.61 years;the urban women's group aged 50～69 have an additional working capacity of 7.86～8.36 years,and the junior high school and above women's group aged 50～69 have an additional working capacity of 5.89～6.33 years.Conclusion Women in China still have great potential for healthy work to be tapped,especially for middle-aged and elderly women with good health in cities and towns and with high education.Reasonably formulating retirement policies for women of different groups and gradually realizing the retirement of men and women at the same age will help to further promote the workplace gender equality and healthy aging.
