根据静态比较优势理论制定的外贸政策 ,只能导致单向的非互惠自由贸易 ,最终的结果多为贸易的不平衡。绝对优势(动态比较优势)不仅是经济发展(不是增长)的决定因素 ,也是贸易模式和贸易商品的决定因素。因此 ,外贸政策的制定应以动态的比较优势为理论依据 ,否则就要自食静态比较优势所带来的非互惠的单向自由贸易的苦果 ,美国今天的贸易赤字就是最好的教训 The foreign trade policy based on the theory of static comparative advantage can only lead to one-way non-reciprocal free trade. The ultimate result is mostly trade imbalance. The absolute advantage (dynamic comparative advantage) is not only a determinant of economic growth (not growth) but also a determinant of trade patterns and trade commodities. Therefore, the formulation of foreign trade policy should be based on the dynamic comparative advantage, otherwise the result of non-reciprocal and one-way free trade brought about by the static comparative advantage will be the best lesson from the U.S. trade deficit today
