摘　　要：贸易成本是经济活动无法回避的一个现实存在,但却被传统贸易理论甚至整个新古典经济学分析框架长期舍弃了,或仅作为影响经济活动的一个外生变量。到了新经济地理学那里贸易成本才得到真正的"复活",被视为左右经济空间分布的核心变量。新经济地理学意义上的贸易成本,属于三个经济学分支"散论"的集合,即国际贸易理论尤其是新贸易理论之方法论、新制度经济学的交易成本论、新经济地理学的分析框架之间的集合。然而即便在新经济地理学那里,贸易成本主要是被当作影响经济空间集聚的一个因素,在相关分析中往往以虚设变量代替贸易成本,且鲜有实在的数据支撑。Trade cost is a real existence in economic activities that cannot be avoided.But it had been excluded deliberately in trade theory and even in the entire framework of the neoclassical economics for a long time,and dealt with only as an exogenous variable.It is not until the NEG(new economic geography) is created when it gets real 'resurrection'.NEG theory takes trade cost as a core variable in affecting spatial distribution of economic activities.Trade cost in NEG sense belongs to a kind of syntheses of some point of view scattered in the three branch of economic theories;a) international trade theory,especially the new trade theory methodology.b) the transaction cost of the new institutional economics.c) an analytical framework of the new economic geography.However,even in NEG model,trade cost is deemed as a factor that affects the spatial distribution of economic activities and replaces the trade cost with little support of real data.
