Increasingly, studies are examining whether the incidence of natural disasters influences household migration. This paper examines whether the severity of natural disasters is important for migration decisions in Vietnam, rather than just examining their occurrence. Data for a sample of 1,003 farm households from the Vietnam Household Living Standard Survey are examined for the period 2006–2008. A residual generated regressor approach is adopted to isolate the direct impact of disasters on migration from the indirect impact they have on migration through reducing agricultural output and income. Findings suggest that more severe disasters are directly associated with a greater probability of migration. Furthermore, such outcomes are the same for poor households vis-à-vis their non-poor counterparts.

自然灾害对移民的影响：越南的调查结果

越来越多的研究正在研究自然灾害的发生率是否会影响家庭迁移。本文探讨自然灾害的严重程度是否对越南的移民决策很重要，而不仅仅是检查它们的发生。对 2006-2008 年越南家庭生活水平调查中 1,003 个农户的样本数据进行了检查。采用残差生成回归量法，将灾害对移民的直接影响与灾害通过减少农业产出和收入对移民产生的间接影响区分开来。研究结果表明，更严重的灾害与更大的迁移概率直接相关。此外，对于贫困家庭来说，这样的结果是相同的相对他们的非贫困同行。
