新生代农民工就业稳定性的工资效应研究——以东莞市为例

A Study of the Effectiveness of Employment Stability for the New Generation Migrant Workers' Wages——Evidence from Dongguan

从工作转换次数、劳动合同期限两个方面界定就业稳定性,通过对新生代农民工就业稳定性的工资效应进行分析,提出了相应的研究假设,并利用2010年东莞市微观调研数据和区间回归模型对相关的研究假设进行实证检验。在控制相关变量的条件下,签订长期劳动合同的新生代农民工工资明显高于短期劳动合同,工作转换次数与工资水平呈负向关系,工作转换过于频繁的新生代农民工其工资水平明显低于没有换过工作的新生代农民工。稳定的就业关系有利于企业进行专用性人力资本投资和新生代农民工企业专用性人力资本的积累,对进一步提升其职业技能水平和工资水平,乃至产业转型升级都有显著的积极作用。

This paper attempts to define employment stability from two aspects:the number of job changes and the term of employment contract.Then we made a preliminary analysis and hypothesis of the effectiveness of employment stability for the new generation migrant workers.We used Dongguan micro survey data in 2010 and interval regression model to test the theoretical assumptions.On the condition of controlling relevant variables,there was a negative significant relation between wages and the number of job changes,that is,the fewer the number of contracts,the higher the income.This paper argues that the stable employment relationship may affect the firms' specific human capital investment and workers' enterprise-specific human capital accumulation,and it may further enhance their professional skill level and significantly play positive effect on the growth of wage.
