摘　　要：以往研究发现,工作转换能够显著提高农民工的工资收入。文章运用7省13市的农民工调查数据和夜间灯光数据检验了工作转换与农民工工资增长之间的因果关系。普通最小二乘法和模糊断点回归的估计结果都表明:农民工通过工作转换实现的工资增长实际反映的是农民工去了一个更好的工作单位或工作城市,工作单位的企业规模和打工城市的经济状况是影响农民工二次流动工资增长的重要因素。但两者的作用存在群体异质性:企业规模只会显著提高换城市流动农民工的工资收入,而对换企业流动农民工没有显著影响;城市的经济状况不仅能够显著提高换城市流动农民工的工资收入,还能显著提高换企业流动农民工的工资收入,经济状况是提高农民工二次流动工资收入更为普遍的影响因素。这些研究发现对于引导农民工在经济新常态时期的工作流动具有重要意义。Previous studies have found that job change can significantly increase migrant workers’wageearnings.Based on the2014survey data from thirteen cities in seven provinces and Night-time Lights Data,thispaper examines the causality between job change and wage growth of migrant workers.The results by ordinaryleast squares(OLS)and fuzzy regression discontinuity(FRD)show that the wage growth of migrant workersthrough job change actually reflects the fact that the migrant workers transfer to a better company or move to abetter city.Company size and economic growth of the city are two important factors affecting the wage increase ofmigrant workers.However,there exists the group heterogeneity.On the one hand,company size can only signifi?cantly increase the wages of the migratory job changers,while it has little effect on the local job changers’.Forthe migratory job changers,the transfer from a smaller company to a larger one may mean a forty percent in?crease in their wages.On the other hand,the Economic growth of the cities can bring about significant increasesin the wages of the migratory job changers as well as the local ones.It is indicated that the move to a more pros?perous city yields a1.3times higher rise in wage than a move to a less developed city,which,therefore,establish?es the economic development of a city as a more common factor determining the migrant workers’wage growth.These findings can reasonably serve as important guides for migrant workers in their work and migration in thenew economic period.
