进城农民教育和工作经验对收入倒“U”型影响的检验

Inverse U-shape Curve Checking on the Influence of Schooling and Jobbing Experience of Migrant Workers on Their Incomes

进城农民群体被看做是缩小城乡收入差距、促进社会和谐发展的关键群体,虽然相关研究深化了有关进城农民劳动力收入决定因素的认识,但是,针对教育和工作经验对中国进城农民收入影响的研究较少,且缺乏对影响是否持续呈线性的研究。基于明瑟扩展方程,结合典型地区数据,分析发现教育和工作经验对进城农民收入具有显著的正向影响,工作经验与收入之间存在倒"U"型关系,而教育与收入之间不存在倒"U"型关系。在分析结论的基础上提出了完善进城农民教育和培训体系等建议。

The groups of migrant workers, i.e. , the farmer-turned workers in different Chinese cities, are regarded as the people crucial to narrowing the income gap between the city and countryside and advancing the economic development in harmony with the society. In this respect, although the decisive factors of their incomes have been studied in depth, the studies on their incomes in relation to their schooling and jobbing experience are rare, especially whether the influence of schooling and jobbing experience presents the linearity. Based on the extended Mincer equation and combining it with the data from a typical city, an analysis is made which reveals that schooling and jobbing experience affect the migrant workers positively obviously and that no inverse U-shape curve found in the relationship between schooling and income. Thus, some suggestions are given as conclusions to perfect the re-education and job training for migrant workers.
