Resource supplies and changing world agricultural comparative advantage
在动态框架下考察赫克歇尔-俄林理论对农业的适用性，发现资源禀赋变化是解释世界农产品贸易结构演变的重要因素，对农业贸易研究者有参考价值。
Abstract This paper advances consideration of the Heckscher–Ohlin (H‐O) theory of comparative advantage to agriculture in a dynamic setting. The dynamic relationship among trade flows, resource supplies, and factor contents is studied. The view that special circumstances in the agricultural sector render the H‐O theory inapplicable as a guide to agricultural trade is challenged. Consistent with the H‐O theory, the results suggest that changing world patterns of resource abundance are an important explanation of the evolving structure of world trade in agriculture commodities.
