空气污染对劳动力回流的影响——基于CHFS调查数据的研究

The Impact of Air Pollution on Labor Return:Based on CHFS Survey Data

随着中国人均收入水平的提高,人们对美好的生活环境的要求也日益强烈,这影响了人们定居和工作的选择。本文采用Probit概率模型分析了空气污染对劳动力回流决策的影响。结果显示,空气污染是影响劳动力回流决策的重要因素,在保持其他条件不变的情况下,AQI指数每增长一个标准差,劳动力回流概率增加10.45%。异质性分析发现空气污染对资产较少、30~44岁的群体、中西部地区人口以及南方地区的人口回流有着更为显著的影响。机制分析部分表明空气污染主要通过影响身体健康、降低工作收入两个微观因素以及地区的产业结构、地区环境规制两个宏观因素影响回流决策。根据研究结论,本文得出要重视环境要素的作用,对回流人口进行扶持以促进乡村振兴和共同富裕等启示。

With the improvement of China's per capita income level,people's requirements for a better living envi-ronment are becoming increasingly strong.It also affects people's choice of where to live and where to work.In this paper,Probit probability model is used to analyze the influence of air pollution on labor return decision.The results show that air pollution is an important factor affecting the decision of labor return.If other conditions remain un-changed,the probability of labor return increases by 10.45%for every one standard deviation increase of AQI index.Heterogeneity analysis found that air pollution has a more significant impact on the population with less assets,the population aged 30~44 years,the population in the central and western regions,and the population in the southern re-gion.The mechanism analysis shows that air pollution mainly affects the return decision through two micro-factors of health and income reduction,and two macro-factors of regional industrial structure and regional environmental regu-lation.According to the research conclusion,this paper draws a conclusion that we should pay attention to the role of environmental factors and support the returning population to promote rural revitalization and common prosperity and so on.
