North American Economic Integration and Industry Location
综述了北美自由贸易对加拿大、墨西哥和美国产业区位的影响，发现墨西哥制造业向北部迁移、技能工资溢价上升，而美加影响较弱，但美墨边境城市就业与墨西哥出口正相关。
Does regional economic integration affect the location of economic activity inside countries? Discussed in this paper is recent academic literature on whether the movement towards free trade in North America has influenced the spatial organization of production in Canada, Mexico, or the United States. In Mexico, closer economic ties with the United States appear to have contributed to a contraction of employment in the Mexico City manufacturing belt, a rapid expansion of manufacturing employment in northern Mexico, and an increase in the wage premiums paid to skilled workers. The effects of economic integration on industry location in Canada and the United States seem to have been much weaker. One exception to this finding is US cities on the Mexican border, whose employment growth is strongly positively correlated with export production in neighbouring Mexican regions. The implication of a possible hemispheric free-trade agreement are also discussed.
