本文应用异质性处理效应模型方法研究了珠江三角洲农村的职业培训，发现：（1）村民的不可观察变量在村民的参与决策和收入获得中发挥了重要的作用；（2）不可观察变量使得那些最有可能参加培训的村民从培训中获得的边际收益最低，反而那些不太可能参加培训的村民的边际收益最高；（3）参加者的处理效应低于平均处理效应，而后者又低于未参加者的处理效应。我们的实证结果隐含的政策建议是政府应该吸引和动员那些不参加职业培训难以提高工资收入的村民参加培训。

Applying heterogenous treatment effect model, this paper estimates the treatment effects of vocational training in rural Guangdong province. We find that （1） the unobservables play an important role for the villagers to decide whether or not participate the training programs, （2） In terms of unohservables, those most likely to partieipate benefit the least from the programs and those not likely to participate benefit the most, （3） the treatment effect for the treated is lower that the average treatment effect and the latter is lower than the treatment effect for untreated. The empirical result suggests the training programs should help the villagers with observed and unobserved characteristics that make them the least likely to increase their non-farming incomes without training.
