Intraindustry Trade: Sources and Effects on Protection
实证分析产业内贸易的决定因素，发现两向贸易发生在有利于国际专业化的条件下，与斯提格勒-威廉姆森分工分析一致，且产业内贸易显著影响保护主义压力，相关产品出口可缓解进口带来的关税提升效应。
This paper provides an empirical analysis of the determinants of intraindustry trade. The authors demonstrat that two-way trade flows occur where conditions are favorable to international specialization consistent with the Stigler-Williamson analysis of the division of labor. The results are inconsistent wit h the prevailing product differentiation-cum-scale economies model of intraindustry trade. In addition, the authors show that intraindustr y trade has a significant impact on protectionist pressures. Exports of closely related products have the effect of mitigating the tariff- raising effects that imports would otherwise exert. Copyright 1987 by University of Chicago Press.
