健康冲击对收入水平的影响——基于CLDS2018的实证研究
The Effect of Health Shock on Income Level—An Empirical Study Based on CLDS2018

基于中国劳动力动态调查(CLDS) 2018年的数据，探讨健康冲击对于收入水平的影响，并分析劳动供给在其中的中介作用。采用OLS回归和中介效应模型进行分析，并运用PSM模型进行内生性处理和稳健性检验。结果表明：遭受健康冲击会导致收入水平显著降低，健康冲击会导致劳动力供给降低，进而导致收入下降，即劳动力供给是这一影响的重要传导中介。异质性分析结果表明，接受过高等教育、缴纳商业医疗保险在遭受健康冲击时对收入的影响不显著，未接受过高等教育、未缴纳商业医疗保险在遭受健康冲击时对收入水平的影响显著。据此提出重视劳动者健康素养的提升；加大对劳动者的医疗保障力度；提高劳动者教育水平等政策建议。
Based on the data of China Labor-force Dynamics Survey (CLDS) in 2018, this paper discusses the impact of health shock on income level, and analyzes the mediating role of labor supply in it. The OLS regression and mediating effect model were used to analyze the model, and the PSM model was used to process the endogenous and test the robustness. The results show that health shock will lead to a significant reduction in income level, and health shock will lead to a reduction in labor supply, which will lead to a decline in income, that is, the supply of labor is an important transmis-sion agent of this effect. The results of heterogeneity analysis show that higher education and pay-ment of commercial medical insurance have no significant impact on income when suffering health shock, lack of higher education and non-payment of commercial health insurance have a significant impact on income levels when suffering health shocks. Based on this, the author puts forward some policy suggestions, such as paying attention to the improvement of workers’ health literacy, strengthening the medical security for the workers, and improving the education level of the work-ers.
