用价值来衡量比较优势的利益存在货币幻觉等不足,应该用产量来衡量比较优势的好处。但是,采用aX/aYbX/bY方法来定义的比较优势掩盖了比较优势陷阱。为深入研究比较优势和比较优势陷阱的关系,运用规范方法,采用aX/aY1bX/bY来重新定义比较优势,创造性地提出"比较优势边界——1"的概念。研究认为,根据比较优势陷阱系数,可以将比较优势陷阱分为"深比较优势陷阱"和"浅比较优势陷阱",当比较优势陷阱系数等于1时,称为比较优势陷阱边界。同时,也可以运用45度对角线原则即比较优势陷阱边界——1来判定某国所处的比较优势陷阱路径,根据该路径可以分析其所实行的国际贸易政策的原因。

Measuring the benefits of comparative advantage by value has some problems such as money illusion, and the good of comparative advantage should be measured by volume of production. But the comparative advantage defined by applying aX/aY>bX/bY covers the comparative advantage trap. In order to thoroughly study the relationship of comparative advantage and comparative advantage trap, criterion method is applied, comparative advantage is redefined by applying aX/aY >1 >bX/bY, and “comparative advantage frontier-1” is proposed creatively. Conclusion is drawn that comparative advantage trap can be divided into “deep comparative advantage trap” and“shallow comparative advantage trap” according to the coefficient of comparative advantage trap, and when the coefficient of comparative advantage trap is equal to 1, it is called comparative advantage trap frontier. At the same time, the principle of 45-degree diagonal, namely, comparative advantage trap frontier-1 also can be used
