This article investigates the impact of flood risk on vulnerability and welfare at the household level in Vietnam. The analytical sample is taken from a household survey conducted in a north central Vietnam community through a three-stage stratified random sampling method. The propensity score matching approach is employed to compare various welfare indicators between flooded and non-flooded households. This study finds that flooding results in significant income losses and imposes higher costs of living, especially housing costs. The two types of households are vulnerable, implying that other natural disasters or socio-economic disadvantages may have adverse effects on households’ livelihoods. The insignificant effect of floods on vulnerability indicates that the flooded households can cope with floods to some extent. However, contrary to family support, formal coping strategies are insufficient or ineffective at reducing household vulnerability to floods.

本文研究了洪水风险对越南家庭一级脆弱性和福利的影响。分析样本取自越南中北部社区的家庭调查，该调查通过三阶段分层随机抽样方法进行。倾向得分匹配法用于比较淹没和未淹没家庭之间的各种福利指标。这项研究发现，洪水会导致严重的收入损失，并带来更高的生活成本，尤其是住房成本。这两种类型的家庭都很脆弱，这意味着其他自然灾害或社会经济劣势可能对家庭生计产生不利影响。洪水对脆弱性的影响微乎其微，这表明被洪水淹没的家庭可以在一定程度上应对洪水。然而，
