本文探讨了1993 - 2004年美国大都市统计区之间工资差异驱动的移民中区域经济结构的作用。区域间贸易的迅速增长归因于国际和区域间生产过程的结构调整。贸易和移民都有助于区域劳动力市场的均衡条件。在区际贸易中，当区域分割增加产业内贸易时，我们是否期望看到区际贸易对区域劳动力市场均衡条件的作用越来越大？碎片化可能会迫使一些生产阶段转移到其他地区，换句话说，企业可能会从搬迁到劳动力成本最低、工资率更低的地区中受益。在这一结构调整过程中，区域经济结构的相似性可能会增加IIT的数量，因此，我们可以期待看到贸易在要素价格均衡方面对移民的补充作用越来越大。相反，当区域经济结构差异较大时，人口迁移比贸易对要素价格均衡的作用更大。因此，由工资差异引起的区域间移徙的主要流动更有可能出现在区域经济结构不同的区域。
This paper explores the role of regional economic structure in the wage differential driven migration among the US Metropolitan Statistical Areas for three discrete time periods from 1993 to 2004. Rapidly increasing interregional trade attributes to the restructuring process of production internationally and interregionally. Both trade and migration can contribute to the equilibrium conditions in regional labor markets. When fragmentation increases intra-industry trade (IIT) in interregional trade, do we expect to see the increasing roles of interregional trade toward the equilibrium condition in regional labor markets? Fragmentation may force some production stages to the other regions, in other words, firms may benefit from relocating to the regions where they can minimize labor costs with cheaper wage rates. In this restructuring process, similarities in regional economic structures may increase the volumes of IIT and as a result, we may expect to see the increasing complementary role of trade in factor price equalization to migration. In contrast, when regional economic structures are quite different, migration rather than trade plays more important role in factor price equalization. Consequently, the main flows of interregional migration caused by wage differentials are more likely to be found among the regions where regional economic structures are dissimilar.
