The transformation from the quantity of labor supply to the quality of labor supply is an important measure to improve the self-development of migrant workers.
Based on the 2018 China Floating Population Dynamic Monitoring Survey data, this paper uses the 2SLS model based on instrumental variable estimation to analyze the impact of urban and rural integrated medical insurance on the quality of migrant workers' labor supply.
The study found that: First, urban and rural integrated medical insurance can significantly improve the quality of labor supply for migrant workers. Even with different instrumental variables and the use of propensity score matching for counterfactual inferences, the findings remain robust. Second, the impact of urban-rural integrated medical insurance on the quality of labor supply for migrant workers has nonlinear characteristics. At the low quantile, the impact of urban-rural integrated medical insurance on the quality of labor supply for migrant workers showed a downward trend, but with the increase of the quantile, the impact of urban and rural integrated medical insurance continued to increase, showing a U-shaped trend.
Urban-rural integrated medical insurance can not only directly reduce the labor time of migrant workers and ease the labor burden of migrant workers, but also indirectly improve the quality of labor supply for migrant workers through the intermediary role of promoting the availability of public services such as family contracted doctor services and health education.
从劳动力供给数量向劳动力供给质量转变,是提高农民工自我发展能力的重要举措。
基于 2018 年中国流动人口动态监测调查数据,本文采用基于工具变量估计的 2SLS 模型,分析了城乡居民基本医疗保险对农民工劳动力供给质量的影响。
研究发现:第一,城乡居民基本医疗保险能够显著提高农民工劳动力供给质量。即使使用不同的工具变量和倾向得分匹配进行反事实推断,研究结果仍然稳健。第二,城乡居民基本医疗保险对农民工劳动力供给质量的影响具有非线性特征。在低分位数处,城乡居民基本医疗保险对农民工劳动力供给质量的影响呈现下降趋势,但随着分位数的增加,城乡居民基本医疗保险的影响持续增加,呈现出 U 型趋势。
城乡居民基本医疗保险不仅可以直接减少农民工的劳动时间,缓解农民工的劳动负担,还可以通过促进家庭签约医生服务和健康教育等公共服务的可及性等中介作用,间接提高农民工劳动力供给质量。
