公平是法律永恒的追求,国际贸易法也不例外。本文首先从GATT到WTO演变发展的角度讨论了自由贸易与公平原则之间的内在关联。在此基础上,以反倾销调查中的非市场经济规则为例,从规则制定与规则实施两个层面,分析了公平原则受到的冲击。此外,基于理想与现实之间的张力,作者也对于应该如何恰当地理解国际贸易法中的公平原则作了分析。 Fair is the eternal pursuit of law, international trade law is no exception. This article first discusses the inherent relationship between free trade and fairness from the perspective of evolution of GATT to WTO. On this basis, taking the non-market economy rules in the anti-dumping investigation as an example, this paper analyzes the impact of the principle of fairness from two aspects: rule making and rule implementation. In addition, based on the tension between ideal and reality, the authors also analyzed how the proper principles of fairness in international trade law should be analyzed.
