Relative Factor Abundance and Trade
提出一种要素含量贸易预测方法，基于赫克歇尔-俄林-瓦内克模型，发现国家间要素禀赋差异越大，其双边要素含量差异越符合模型预测，对南北贸易尤其显著。
I develop a factor content of trade prediction for the Heckscher-Ohlin-Vanek model (HOV) that relates bilateral differences in country endowments to bilateral differences in factor contents. The results are striking. In comparisons of North-South factor contents or factor contents of countries with very different endowments (e.g., with very different capital-labor ratios), there is clear support for an HOV sign prediction. Thus countries with dissimilar endowment ratios also have very different factor content of trade differences as predicted by the HOV model.
