工作转换、流动与农民工收入增长

Job Change,Urban Mobility and Wage Growth of Migrant Workers

本文利用2008年实施的中国住户收入调查数据的城市移民数据分析了农民工工作转换、城市流动及其收入增长。研究发现,有工作转换经历的农民工总体中38%为当地工作转换者,62%为迁移型工作转换者。决定二者收入增长的因素存在差异:受教育程度对当地工作转换者更重要,教育水平越高越有利于其获取高收入增长;而具有经验和专有人力资本积累的农民工通过迁移型工作转换可以获得更高的收入增长。简单的变换城市变量无法准确衡量其对流动就业农民工的收入增长效应。区分不同方向的城市流动后发现,农民工在转换工作时从西部城市、中部城市流动到东部城市均可显著提升其收入增长情况;反方向的流动则不利于其收入增长。

Using the urban migration data of CHIP data that is executed in 2008,this paper examines the job change,urban mobility and wage growth in a sample of migrant workers who have the experiences of job mobility. The results show that overall 38% of migrant workers are local job changers,62% migratory job changers. There are differences in the determination of wage growth between the two types of migrant workers: the level of education is more important for the local job changers,the higher education the higher wage growth. The experience and the firm-specific human capital accumulation are key factors for the migratory job changers to gain more wage growth. The variable of change cities can not accurately measure the additional revenue growth effect of migrant workers,After distinguishing the different direction of urban mobility,we find the job changers who flow away from the western city,and those who flow to the eastern city from the midland city can significantly improve their wage growth; Flow in the opposite direction is unfavorable to their revenue growth significantly. There is no doubt that the results are biased due to ignoring the urban mobility behavior and its effects on the revenue growth when we study the migrant workers only from the perspective of job changes.
