摘要：

发展中国家总是面临着是按初始比较优势还是按潜在比较优势进行国际分工和贸易的两难。发展中国家按初始比较优势进行分工和贸易不一定能使贸易利益增加, 而按潜在比较优势专业化生产学习效应强的产品则能得到动态贸易利益。虽然外部效应下的产业内贸易模式仍依赖于要素禀赋状况, 但比较优势是动态的, 一国在某种产品上的比较优势关键取决于所选择产品的“干中学”效应是否强。在外部报酬递增和产业内贸易的情形下, Rybczynski定理和Stolper-Samuelson定理是否成立依赖于外部报酬递增产出弹性的大小; 同时, 产业内贸易福利是否增进也依赖于双方贸易产业的外部报酬递增弹性的大小。

关键词: 外部效应, 报酬递增, 动态比较优势, 产业内贸易

Abstract:

Developing countries are always facing a dilemma: to perform their international divisions and trade just in accordance with their initial comparative advantages or their potential comparative advantages.According to the former, developing countries are not bound to obtain trade gains, and according to the latter, those products possessing strong learning effectiveness in the specialized production can gain dynamic trade benefits.Although the model of trade within industry under external effects still depends on elemental endowments, the comparative advantage of a national product is dynamic, since it depends on whether the selected product has a powerful effect of "learning through doing"or not.Under the circumstances of external payment increase and trade within industry, whether the Rybczynski formula and Stolper—Samuelson formula can be proved correct depends on the magnitude of output resilience with the increase of external payment.Meanwhile, gains in trade within industry also depend on the flexible range of external payment increase in both parties' trade industry.

Key words: external effect, payment increase, dynamic comparative advantage
