Factor Content Functions and the Theory of International Trade
引入直接和间接贸易效用函数，推导出马歇尔和希克斯要素含量函数，用于表达净进口中蕴含的生产要素数量，并证明在某些情况下贸易收益的存在足以使赫克歇尔-俄林定理的要素含量形式成立。
This paper introduces the concepts of direct and indirect factor trade utility functions and uses them to derive Marshallian and Hicksian factor content functions, which express the quantities of factors of production embodied in net imports as functions of the exogenous variables facing the economy. The properties of these functions are discussed and they are used to derive a number of new results. In particular, it is shown that, in certain circumstances, the existence of gains from trade is sufficient for the Heckscher-Ohlin theorem to hold in its factor content form.
