我国单位物流成本对国际贸易的影响——基于贸易引力模型的实证分析

用单位货物周转费用代表单位物流成本，考察物流对贸易的影响，引入贸易引力模型并对其进行合理的改进。并提出模型的理论假设。通过回归分析和因果关系检验，可以得到的结论是：单位货物周转费降低对国际贸易具有明显的促进作用，证明了中国与世界上其他国家的双边货物贸易额与双方的人均收入成正比，与单位货物周转费用成反比。既验证了传统贸易引力模型的正确性。也肯定了对贸易引力模型说进行的改进。

Influence of Unit Logistics Cost on International Trade Based on Empirical Analysis on Trade Gravity Model

This paper takes turnover cost of unitized cargo as unitized logistics cost,researching influence of logistics on trade,and introduces trade gravity model and reform it reasonably to present a theoretical hypothesis on the model.Through regression analysis and granger causality,this paper concludes that the decline of turnover cost of unitized cargo will promote international trade obviously,i.e.there exists positive relations between the bilateral trade volume and their income per capita between China and ...
