摘　　要：基于2006年吉林省进城务工人员调查数据,采用倾向分匹配法对农民工的培训收入效应进行估算。研究结果表明:培训对农民工的收入确实有显著的积极的影响,其中职前培训的增收效果明显高于在职培训。横截面估计和OLS估计的结果也支持这一结论。同时通过比较不同方法中的受试组和参照组个体统计特征发现,倾向分匹配法中参照组的个体统计特征更接近于受试组,亦即基于倾向分匹配法获得的估计结果更接近于随机实验结果。The paper uses the propensity score - matching method to estimate the effects on training on rural labor＇ s earnings based on micro data of Jilin Province in 2006. The estimating results show that both pre - job and on - the - job training have positive effects on rural labors, and the former is higher than the latter. Cross -sectional estimates and OLS estimates also demonstrate the conclusion. But comparing between treatment group and control group in different methods, we find that individual characters are closer between them in propensity score - matching method than others. That is, the estimates of propensity score - matching method are closer to that of random experiments.
