It not only innovates the traditional theory of international trade, but also makes a conclusion that is more in line with the reality of today’s international trade. This article will explain the innovation of Paul Krugman’s new trade theory from five aspects: the reason of international trade, the trade advantage, the new mode of international trade, the new trend of international trade and the dumping of products.
