国際貿易は、そこから生じる大きな実利によって、計り知れない利益をもたらします。国際貿易の重要性についての確信をいっそう強めるのは、超大国どうしが新たな市場の獲得や、自国の商品を売り込み、原材料を障害なく輸入できる既存市場の保護をめぐって、激しく争い、熾烈な競争を繰り広げているという事実です。国際貿易には、数多くの特徴、利点、そして結果があります。国際貿易が成立する主な理由は、国によって商品の比較費用に差があることです。したがって、各国で比較費用が異なる以上、すべての国にとって、相互に国際貿易を確立することが利益にかなうのです。

International trade yields a tremendous benefit due to the high real profits which are generated from it. What adds to a person’s conviction about the importance of international trade is the ferocious fighting and fierce competition between the superpowers over the acquisition of new markets and the protection of old markets, to which their merchandise is disposed of, and from which they import raw materials without obstacle. International trade has a host of distinguishing features, merits and outcomes. The main reason behind the establishment of international trade is the disparity in the proportional costs of commodities between one country and another. It would therefore be in the interest of all countries to establish international trade between them once the proportional costs differed in each country.
