中国进出口双边贸易成本测度方法比较研究

Measurement of the Bilateral Trade Cost

目前测度贸易成本广为应用的Novy方法存在实践性缺陷,本文直接基于Andersen多边一般均衡微观需求建模思路,重构可行的出口贸易成本测度方程,并以中国经验数据为例证与原有方法进行了对比分析。结果表明,两种方法存在稳健的测度差异,很有必要认真探讨。近年来中国与主要贸易伙伴双边贸易成本整体加速下降,亚太地区及北方邻国贸易成本明显小于其他地区。

Barriers to international trade are known to be large but because of data limitations it is hard to measure them directly for a large number of countries over many years.To address this problem,the paper derives a micro-founded measure of bilateral trade resistance that indirectly infers trade frictions from observable trade data.In an application it shows that China trade resistances with major trading partners declined on average between 2000 and 2011.China and the Asia-Pacific region trade resistance is significantly less than in Europe.
