国有部门与非国有部门工资差异及人力资本贡献

本文利用微观调查数据,对我国国有部门与非国有部门的工资差异进行了实证研究。在对工资差异进行分解后,本文发现,我国国有部门的工资优势中有80%以上来自于人力资本的优势,这说明人力资本在国有部门的工资决定中已经发挥了决定性作用。但人力资本对工资差异的贡献在工资分布区间并不均匀,它随着工资从高分位点到低分位点逐渐降低,与此对应的是工资溢价随工资从高分位点到低分位点逐渐升高。从工资差异看,在工资分布的高端——高知识高技能人才的密集区,工资差异完全体现为人力资本的差异,而在工资分布的低端——低技能劳动力的密集区,工资差异有很大一部分是人力资本无法解释的,也即溢价。本研究认为,造成这种现象的原因在于国有部门"共享式"的工资决定模式。这种模式倾向于在压低高技能劳动力的报酬率的同时,抬高低技能劳动力的报酬率。所以国有部门的工资决定应进一步强化人力资本的报酬机制,以提高效率,增强竞争力。

State and Non-state Sector Wage Differentials and Human Capital Contribution

This paper analyses wage differentials between state-sector and non state-sector in China using household survey data. The decomposition of the wage differentials between the two sectors show that there are more than 80% wages advantages come from the advantages of human capital of state-sector. This indicates that human capital has been the key factor in state-sector wage determination. But the contribution of human capital across the wage distribution is not uniform. It declines monotonically with movemen...
