Import Competition and Internal Migration
研究美国给予中国永久正常贸易关系后，进口竞争加剧如何影响国内人口迁移，发现受冲击大的地区十年后人口增长相对放缓，尤其对年轻人和低教育群体影响显著。
Abstract We examine the U.S. internal migration response to increased import competition following the granting of Permanent Normal Trade Relations to China in 2001. Using a variety of data sets and empirical approaches, we find that local labor markets most exposed to the policy change experienced a relative reduction in population growth over the following decade. The majority of the effect occurs at a lag of seven to ten years and is most pronounced among young individuals and low-education groups. Such population adjustments should influence the interpretation of evidence in the growing literature on import competition and local labor markets.
