农民工为何频繁变换工作——户籍制度下农民工的工作流动研究

中国劳动力市场可按三种形态分割：再分配机制下体制内外的分割、市场机制下人力资本高低的分割和户籍制度下城乡身份的分割。城乡身份分割是影响农民工频繁变换工作的关键因素。本研究利用事件史模型，比较农民工与城市工人的工作流动，对不同时期农民工的工作流动进行分析。研究发现：尽管存在人力资本和所处部门对其工作流动的影响，但户籍歧视仍作为一个独立因素影响农民工的工作稳定性，但这种影响随社会发展正在降低。

Why are the Rural Migrant Workers so Prone to Job Change:Job Mobility of Rural Migrant Workers within the Constraint of HukouSystem

The labor force market in China is segregated along three dividing lines: being inside or outside the redistributive state system, having high or low human capital under the market system, and whether registered with a rural or an urban identity in the hukou system (household registration system). The third division is believed to be the key factor that has been associated with the rural migrant workers’ frequent job changes. This study adopts the model of event history analysis to compare the job mobility of urbanites and rural migrants and to examine the latter group’s job mobility patterns in different historical periods. The results show that, although human capital and work sector influence job changes, domicile discrimination contributes uniquely to rural migrants’ job stability. Its impact, however, is decreasing with the development of society.
