摘要
本文通过构建收入决定模型,利用Blinder-Oaxaca分解法将公、私部门收入的差异分解为反事实合理收入差异与反事实收入溢价,通过对反事实收入溢价的分析发现：控制诸如教育水平、性别、职业、工作经验等常规收入决定因素之后,公共部门平均工资和月收入①与私人部门相比均相对偏低②;但当引入区域变量时,公私部门的收入情况出现变化——公共部门平均工资与私人部门相比仍相对偏低,但考虑地域因素后的公共部门平均收入高于私人部门。实证表明,我国公、私部门平均工资的地区性差异不大,但公、私部门的平均收入水平差异具有较强的地区差异敏感性,这种显著的地区差异导致对公共部门收入的＂一刀切＂式简单变革,反而会增大我国公、私部门间收入对于＂同工同酬＂原则的扭曲。
By constructing income determination method and using Blinder-Oaxaca decomposition method,this paper decomposes the income differences between the public and private sector into counterfactual reasonable income difference and counterfactual income premium. Through the analysis of counterfactual income premium,it is found that compared to the private sector,the average wage and month income of public sector are both relatively low when we control education,gender,occupation and experience. But the income of public sector is relatively high when we add area variable into the model. The conclusion indicates that the differences in average income are more sensitive to area. The significant regional differences lead that the simple reform for the public sector income with the same type will increase the distortion of the＂equal pay for equal work＂principle which should be followed in the public and private sector income.
