Abstract:

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.

Key words: Income Difference between the Public and Private Sector, Blinder-Oaxaca Decomposition Method, Relatively Low
