Factor Proportions and the Structure of Commodity Trade
结合赫克歇尔-俄林模型与克鲁格曼的垄断竞争模型，研究要素比例如何决定商品贸易结构，发现国家在密集使用其充裕要素的商品上占有更大生产与贸易份额，且要素积累会推动生产与出口结构向密集使用该要素的行业转移。
This paper examines how factor proportions determine the structure of commodity trade. It integrates a many-country version of a Heckscher-Ohlin model with a continuum of goods with Paul R. Krugman's (1980) model of monopolistic competition and transport costs. The commodity structure of production and bilateral trade is fully determined. Two main predictions emerge. Countries capture larger shares of world production and trade of commodities that more intensively use their abundant factors. Countries that rapidly accumulate a factor see their production and export structures systematically shift towards industries that intensively use that factor. Both predictions receive support from detailed trade data.
