内容提要本文将健康风险与医疗保险引入劳动参与模型与工作流动模型,通过动态规划方法构造理论模型并模拟健康风险对劳动者劳动供给决策和工作流动决策的冲击,以及医疗保险的作用。模拟发现医疗保险降低城镇劳动力的劳动参与率,提高农村劳动力的劳动参与率;医疗保险使得城镇劳动者的工作流动率提高,农村劳动者的工作流动率降低。本文还基于CHNS数据进行实证分析,研究发现:城职保与城居保会降低劳动者的劳动参与率,而合作保险则会提高劳动者的劳动参与率;城居保会提高劳动者的工作流动率,而合作保险则会降低劳动者的工作流动率;城职保会提高劳动者的劳动供给时间,合作保险会降低劳动供给时间。考虑到样本异质性差异,基于不同年龄与不同收入子样本的研究并未改变基本结论,但医疗保险的影响程度存在显著的差异。本文还采用双变量probit模型和联立方程模型进行稳健性检验,结果并未改变基本结论。 
AbstractThis paper extends the labor supply model and job turnover model by introducing the health risks and medical insurance. Through the simulation of the theoretical model based on dynamic programming approach, this paper discusses the impact of health risk on labor supply decisions and job turnover decisions, as well as the role of medical insurance. The simulation shows that: the medical insurance decreases the labor supply of urban labor force, while it increases the labor supply of rural labor force, and the medical insurance increases the job mobility of urban labor force, while it decreases the job mobility of rural labor force. The empirical analysis using the data of CHNS finds that: Urban Employee Basic Medical Insurance(UEBMI) and Urban Resident Basic Medical Insurance(URBMI) decrease labor supply, while Cooperative Medical Insurance(CMI) increases labor supply, URBMI increases job mobility, while CMI decreases job mobility, and UEBMI increases the working hours of labor force, while CMI decreases the working hours of labor force. Concerning the sample heterogeneity, the research based on different age and different income subsamples does not change the basic conclusion, but there is a significant difference in the impact of medical insurance. Furthermore, robustness test by bivariate probit model and simultaneous equations model does not change the basic conclusion.
