在本文中，我们采用社区一级的数据，从越南研究是否有三种类型的自然灾害对移民数字的影响。因此，我们区分了临时和永久移民，也区分了最近发生的灾害事件的影响和中期灾害趋势的变化。我们发现，间歇性的干旱和洪水事件往往会导致移民从受影响的公社。虽然干旱主要造成临时移徙，但洪水事件往往导致永久性地迁离受影响地区。在过去十年中，每当干旱或洪水事件被认为变得更加严重时，我们也发现受影响社区的移民人数系统性地增加。偶发台风或台风恶化趋势在短期和长期内仍然没有任何重大影响。
In this paper we employ commune-level data from Vietnam to study whether three types of natural disasters have an impact on emigration figures. We thereby distinguish between temporary and permanent emigration and also differentiate between the effects of recently occurring disaster events and changes in medium-term disaster trends. We find that episodic droughts and flood events tend to cause emigration from the affected communes. While droughts primarily cause temporary migration, flood events tend to induce permanent moves out of the affected regions. Whenever drought or flood events are perceived to have become more severe over the last decade, we also find systematically higher emigration from the affected communes. Episodic typhoons or worsening typhoon trends remain without any significant effect in both the short- and the long-run.
