Two-by-Two International Trade Theory with Many Goods and Factors
用对偶理论将两商品两要素赫克歇尔-俄林模型的性质推广到任意数量商品和要素、联合生产、要素国际流动等更一般情形，并考察了部门特定要素及商品与要素数量相等时的结果。
This paper adopts a new approach to the problem of generalizing the properties of the two-by-two Heckscher-Ohlin model, asking whether we can obtain results which hold in very general models for dichotomous categories of commodities and factors. Using duality theory, some results of this kind are derived, which generalize certain properties of the Heckscher-Ohlin model to models which allow for any number of goods and factors, joint production, international factor mobility, and substitution between primary factors and intermediate inputs. The consequences of assuming sector-specific factors and equal numbers of goods and factors' are also examined.
