基于比较优势及规模经济的国际贸易万能公式探讨

为了探讨国际贸易发生的真正原因,定义了比较优势势力和规模经济势力的概念。运用对比方法和图形方法,通过放松一些假设条件来考察"两个版本"的规模经济引发国际贸易的过程,将比较优势和规模经济统一起来,发现了国际贸易"万能公式"。研究结论认为:比较优势和规模经济共同引发了国际贸易,在引入"补偿贸易条件线"概念条件下,可以将国际贸易的起因分解成比较优势势力效应和规模经济势力效应。同时,国际贸易"万能公式"可以用来解释里昂惕夫之谜。

Study on the Universal Formula of International Trade Based on the Comparative Advantage and the Economies of Scale

In order to discuss the real cause of the international trade, this paper has defined two new concepts that are the comparative advantage power and the scale economic power. Making use of the comparative method and the graphical method, this paper has unified the comparative advantage and the scale economy, and found out the international trade ＂ universal formula＂ through relaxing some assumptions to study the process of international trade caused by the scale economy including ＂ two versions＂ Conclusion is drawn that the comparative advantage and the scale economy have caused international trade in common. Under the condition of introducing ＂compensation trade condition line＂, the cause of the international trade is decomposed into the comparative advantage power effect and the scale economic power effect. Meanwhile, Leontief paradox may also be used to explain the international trade ＂universal formula＂.
