Using the updated data from the 2016 Vietnam Household Living Standard Survey, this study examines the role of education in the livelihood of households in the Northwest region, the poorest region in Vietnam. Our micro-econometric analysis shows that education has a positive effect on choosing better livelihoods, household income and poverty reduction, even after controlling for all other factors in the models. However, our quantile regression analysis reveals that the returns on education are substantially heterogeneous across percentiles of income distribution and tend to be higher for better-off households. This implies that education has an increasing effect on within-level income inequality. The finding suggests that a conventional approach employing only mean regression to study the effect of education on income could miss heterogeneity of interest to policymakers.

越南西北地区教育在家庭生活中的作用

本研究使用2016年越南家庭生活水平调查的更新数据，研究了教育在西北地区（越南最贫困的地区）的家庭生计中的作用。我们的微观计量经济分析表明，即使在控制了模型中的所有其他因素之后，教育也对选择更好的生计，家庭收入和减少贫困​​产生积极影响。但是，我们的分位数回归分析显示，在收入分配的百分位之间，教育的回报率基本上是异质的，对于富裕家庭而言，教育的回报率往往更高。这意味着教育对内部收入不平等的影响越来越大。
