摘要 文章基于中国劳动力动态调查数据,分析工作时间对流动人口健康状况的影响并对工时健康差异进行分解,采用中介机制分析其影响机理。研究发现,与正常工时者不同,超时工作者工作时间显著降低了其健康水平。工作时间明显扩大了正常工时者与超时工作者自评健康差异、心理健康差异和BMI指数差异。除BMI指数差异外,女性工时自评健康差异和心理健康差异高于男性。与其他维度相比,男性工时BMI指数差异、女性工时自评健康差异更多由可观测因素造成。流动人口工时自评健康差异和心理健康差异最大的是西部,而工时BMI指数差异最大的是东部。随年份推进,流动人口工时健康总差异呈扩大趋势,且可观测因素对工时心理健康差异和BMI指数差异的解释能力逐渐减弱。锻炼时间和睡眠状况是工时影响流动人口健康的中介变量,且对不同工时群体存在不同的中介效应。 Based on the data of China’s Labor Force Dynamic Survey,this paper analyzes the influence of working hours on the health of floating population and decomposes the health difference.It explores the intermediary mechanism of working hours on health.The study finds that working hours significantly deteriorate the health status of overtime workers.Working hours significantly exaggerate the differences in self-rated health,mental health and BMI index between normal workers and overtime workers.The working hours make greater differences in self-rated health and mental health for females than for males.Compared with other health dimensions,the differences in BMI index for males and self-rated health for females were more explainable by observable factors.For the floating population,the largest difference in self-rated health and mental health was in the western areas,while the largest difference in the BMI was in the eastern areas.The overall health difference between regular workers and overtime workers enlarges over time among the floating population,and the health difference explained by observable factors declines for mental health and BMI.Exercise time and sleep condition mediate the effect of working hours on health,and it is heterogeneous among different working groups.Research on the Changing Spatial Gravity of China’s Population,Economy,and Industry Center:Based on the Provincial Data from 1978 to 2019 Zhang Jianwu and Others·64·Based on the data of 31 provinces in China from 1978 to 2019,this paper uses the"gravity center"method to analyze the spatial changes of China’s population,economy,and industry center,and it outlines the track of 8 specific industries’gravity centers in longitude and latitude dimensions.The results show that:(1)since 2010,the gravity centers of population,economy,and industry have all shifted toward southwest,but the situation of their overall agglomeration in the southeast coast has not changed.(2)Compared with the economy and industry gravity centers,the population gravity center in China has changed little,and the inter-region development is still unbalanced.The gap between the east and the west is attributed largely to the primary industry,and the gap between the north and the south is caused by the tertiary industry.(3)From the perspective of sub-sectors,the internal differences in the primary industry are caused by agriculture,forestry,animal husbandry and fishery.The internal differences in the secondary industry are caused by industry.The east-west differences in the tertiary industry are dominated by the financial industry and real estate industry,and the north-south differences are mainly resulted from wholesale and retail industry.It is important to give full play to the comparative advantages of each region,allocate resources and relocate industries rationally,and promote coordinated regional development.
