【摘要】：我国的城镇劳动力市场分割形式多样。本文利用中国城镇家庭调查数据,基于回归、分解和倾向值匹配等方法展开实证分析,考察在不同雇佣合约下工人收入的影响因素是否存在显著差异,并进一步区分不同雇佣类型工人的收入差距是市场有效性的反应还是市场分割带来的租金。回归结果表明,雇佣合约期限与收入之间存在正向关系,不同雇佣合约关系下的工人收入决定机制存在差异。进一步的分解发现,在均值和不同分位数上分割效应对收入差距的解释程度始终高于禀赋效应,即不同雇佣合约类型之间存在劳动力市场分割现象。本文还采用分层倾向值匹配去除可观测的样本选择偏差,结果进一步验证了不同雇佣合约之间存在劳动力市场分割导致的收入差距这一结论。
[Abstract]:China's urban labor market segmentation forms are diverse. Based on the data of urban household survey in China, this paper makes an empirical analysis based on regression, decomposition and preference value matching to examine whether there are significant differences in the influencing factors of workers' income under different employment contracts. It further distinguishes whether the income gap of workers of different types of employment is the reaction of market efficiency or the rent brought by market segmentation. The regression results show that there is a positive relationship between the duration of employment contract and income, and there are differences in the mechanism of determining workers' income under different employment contract relationships. Further decomposition found that the segmentation effect on the mean and different quartiles explained the income gap higher than the endowment effect, that is, there exists labor market segmentation among different types of employment contracts. In this paper, hierarchical preference matching is used to remove observable sample selection bias, and the result further verifies the conclusion that there is income gap caused by labor market segmentation among different employment contracts.
