Technical Differences and Inter-Industry Trade in the Nordic Countries
研究了北欧国家间贸易中的产业间专业化，发现技术差异和资本劳动比共同决定净出口，国家在相对劳动生产率高和研发支出高的行业成为净出口国，同时也在密集使用其充裕要素的行业成为净出口国。
Interindustry specialization in intra-Nordic trade is studied in the context of a simple model where technical differences and capital-labor ratios interact in determining net export. The empirical test largely concurs with the theory. Countries are net exporters in industries where their relative labor productivity is high and where they have high R&D expenditures. In addition, countries are net exporters in industries that make intensive use of their abundant factor. Copyright 1996 by The editors of the Scandinavian Journal of Economics.
