The Impact of Health Shock on Labor Supply of Rural Middle-aged and Elderly People:Effect Evaluation and Evidence of Mechanism

利用中国健康与养老追踪调查(CHARLS)数据来分析健康冲击对农村中老年人劳动供给的影响。发现健康冲击对农村中老年人的劳动供给有显著的负向影响,导致其周工作时间显著减少3.16到3.69小时,并且使其继续工作的可能下降2.9%,受到冲击后仍继续工作的农村中老年人周工作时间显著的减少2.20到2.67小时。农村中老年人劳动供给的下降主要源于健康冲击使周工作时间小于40小时的群体的周工作时间显著减少5.29到5.50小时。健康冲击使得农村中老年人心理健康和客观健康显著下降是其劳动供给减少的重要原因。

In this paper,the impact of health shock on the labor supply of rural middle-aged and elderly people was analyzed with data of China Health and Retirement Longitudinal Study(CHARLS).The results suggested that the health shock has a significant negative effect on the labor supply of the rural middle-aged and elderly people,resulting in a significant reduction of 3.16 to 3.69 hours of weekly working time,and a 2.9%decrease in the possibility of continuing to work.After the health shock,the weekly working time of rural middle-aged and elderly people who still continue to work is significantly reduced by 2.20 to 2.67 hours.The decline of the labor supply of the middle-aged and elderly in rural areas is mainly due to the impact that the weekly working hours of the group whose working hours are less than 40 hours are significantly reduced by 5.29 to 5.50 hours.The main reason for the decrease of labor supply is that the mental health and objective health of the middle-aged and old people in rural areas are significantly reduced due to the health shock.
