Abstract: This paper examines the heterogeneous effects of education and work experience on job quality of migrant workers measured from income, working hours, and social insurance in Chinese cities. Results show that both the years of schooling and work experience are positively correlated with the overall job quality. The years of schooling affect all three dimensions of job quality, while work experience does not significantly influence working hours. The marginal returns to years of schooling are 9 times higher than those to work experience. Further, education has indirect effects on job quality through influencing occupational levels and formal/informal employment while work experience does not. Education not only fundamentally sets the starting point of job quality by influencing the attributes of migrant workers' first job, but also indirectly affects the further improvement of job quality as indicated by the significant differences between the returns to human capital (i.e. years of schooling and work experience) in jobs at different levels.

摘要： 构建工作收入、工作时间和社会保障三维度综合就业质量指标体系，分析受教育年限与工作经验人力资本对流动人口就业质量的影响及其路径。结果显示：受教育年限对流动人口就业质量及其各维度的影响程度都高于工作经验，且后者对工作时间没有显著影响；受教育年限能够通过职业层次和就业正规性的显著中介效应间接影响就业质量，而工作经验对就业质量只有直接影响。从生命历程的角度解析教育对流动人口就业质量的关键作用：迁移就业前的教育水平在很大程度上决定流动人口的职业层次，低层次就业者的工作经验边际回报更低、就业质量提升空间受到限制，进而加剧流动人口就业质量的群体分化。
