珠江三角洲青壮年农民工台阶指数的人口学特征分析

Analysis on Demography Characteristics of the Step Index of the Young and Middle-aged Migrant Workers in the Pearl River Delta

对珠三角城市农民工进行体质测试并结合调查所获取的人口学资料,探讨人口变量和工作负荷因素对台阶指数的影响。通过最优尺度回归对台阶指数起独立影响作用的重要度进行分析。结果显示:工作年限与每天工作时间长短对台阶指数具有重要的影响作用。男女农民工每天工作9 h以上的台阶指数显著低于9 h以下的人群。在收入与健康的关系上,除绝对收入的影响外,还需要考虑性别因素的影响。受教育程度高的台阶指数低于受教育程度较低者,显示受教育程度高者付出更多的工作努力获得较好的经济回报,但这种工作负荷直接或间接地影响到健康水平的提升。

By investigating the physical fitness of the migrant workers in the Pearl River Delta cities, together with the demography information obtained in the research, this thesis explored the influences of individual variables and the workload factor on the step index. Meanwhile, the importance of the independent influence of the step index is analyzed through the optimal scaling. The results showed that： the working years and the length of daily working hours had significant influences on the step index. The step index of the male and female migrant workers working above 9 hours were considerably lower than those of the population working below 9 hours. In respect of the correlation between income and health, in addition to the influence of the absolute income, the impact of the gender factor also should be taken into account. Furthermore, the well - educated population suffered lower step index than those poorly educated, suggesting that the well - educated made more efforts in gaining economic returns. Such workload, however, directly or indirectly impacted the improvement of the health level.
