物流绩效对中国机械运输设备出口三元边际的影响——基于“一带一路”沿线国家面板数据分析

The Impact of Logistics Performance on the China's Export Ternary Margins of Machinery and Transport Equipment——Based on the Panel Data of Countries Along “The Belt and Road”

本文选取世界银行发布的物流绩效指数来衡量一个国家的物流绩效综合水平,并运用拓展贸易引力模型实证分析"一带一路"沿线各国物流绩效对中国机械运输设备出口三元边际的影响。研究表明,"一带一路"沿线各国物流绩效对中国机械运输设备的出口有显著的促进作用,这种贸易促进作用主要体现在数量边际的贡献上,对价格边际的贸易促进作用略高于扩展边际; 6个不同维度上的物流绩效指数对中国机械运输设备出口三元边际产生不同幅度的影响,针对不同的贸易增长模式,需有针对性的提供差异化的政策指导;物流绩效水平偏高国家的物流绩效对中国机械运输设备出口价格边际的促进作用显著,而物流绩效水平偏低国家的物流绩效对价格边际的作用并不明显。

Selecting logistics performance index issued by the World Bank to measure the country's comprehensive logistics performance.This paper,by applying the expanded trade gravity model,empirically analyzes the impacts of logistics performance of countries along“The Belt and Road”on the China's export ternary margins of machinery and transport equipment.The results indicate that the logistics performance of countries along“The Belt and Road”can significantly promote the export of China's machinery and transportation equipment,mainly by contributing to the quantity-margin,meanwhile,the promotion of price-margin is slightly higher than the extensive margin;the logistics performance index in six different dimensions causes different marginal effects on China's machinery and transport equipment export ternary marginal,of which the services and the shipment are the key factors;the logistic performance of the countries with high logistics performance has a significant effect on the export price margins of China's transportation machinery,while the logistic performance of the countries with low logistics performance has no obvious effect on the price margins.
