摘要
李嘉图比较优势理论的新古典经济学的现有几何图形分析存在着两个明显的不完善之处:一是在研究过剩供给时没有考虑到贸易之后各国实际国民收入的变化对国民需求变化的影响,从而使得现有分析对某些问题的解释不够清楚,在作几何图形时具有较大的随意性;二是在分析大国与小国之间的贸易时对有关问题解释得不清楚。本文在数理分析的基础上,指出了现有分析的这两个不完善之处,为完善李嘉图比较优势理论的新古典经济学分析补充了必要的内容,供广大学者在教学与研究当中参考。
There are two evident imperfect analysis in the existing geometric analysis of Ricardo Theory of Comparative Advantage in Neoclassical Economics. Firstly, The existing analysis does not consider the effect of the improved national income on the change of the national demand after the division of labor between the two countries has happened, which leads to ambiguous explana- tions for some important problems and being at discretion when making geometric analysis; Secondly, existing analysis can not make explicit explanations for the relative problems when studying the trade between a big country and a small country. In order to perfect the analysis of Ricardo theory of comparative advantage in neoclassical economics, this paper points out the two imperfect analysis based on the analysis of mathematical economics and supplements the necessary analysis for reference.
