摘　　要：本文基于CHNS的微观调查数据,运用Heckman样本选择模型对我国城镇居民的就业选择和工资收入进行了实证估计,进而运用修正的Oaxaca-Blinder分解和Quantile分解对公共部门与非公共部门的工资差异进行了均值分解和分位数分解。研究发现,在第一阶段(1992～1996年),公共部门工资均值低于非公共部门;在工资分布区间的高端,特征差异不显著;非公共部门存在显著正的工资溢价。在第二阶段(1999～2008年),公共部门工资均值显著高于非公共部门,而且差异呈递增趋势;在整个工资分布区间内,特征差异显著;在工资分布区间的中低端,公共部门存在显著正的工资溢价;在工资分布区间的高端,工资溢价不显著。同时,在这一阶段,公共部门的教育和工作经验存在显著正的工资溢价。Based on CHNS data and the Heckman sample selection model,this paper conducts empirical estimation of the employment choice and the wages of China＇s urban residents,and then uses the modified Oaxaca-Blinder decomposition and Quantile decomposition to decompose the public and non-public sector wage differences.The conclusions are： In the first phase（1992-1996）,the mean wage of the public sector is lower than the non-public sector,in the high end of wage distribution there is significant positive wage premium in the non-public sector.In the second phase（1999-2008）,the mean wage of public sector is significant higher than the non-public sector,and the differences show an increasing tendency;the characteristic difference is significant in the whole wage distribution;there are significant positive wage premium in the mid and low end of wage distribution;in the high end of wage distribution has no significant positive wage premium.At the same time,education and work experience have significant positive wage premium in public sector.
