摘　　要：港口是“一带一路”的重要节点,港口效率的提升为共建“一带一路”高质量发展提供强有力的支撑。本文基于中国沿海11省市对“一带一路”沿线国家的出口数据,运用引力模型实证检验港口效率对出口二元边际的影响。研究表明:中国沿海各省以及“一带一路”沿线国家港口效率存在较大差异;港口效率的提高显著促进中国对“一带一路”沿线国家出口的二元边际;港口效率对工业品出口二元边际的促进效应大于农产品;港口效率对“一带一路”不同区域的影响存在较大的异质性;进一步控制内生性后发现:沿线各国港口效率的提高对中国出口的扩展边际作用大于集约边际。Ports are an important node of the "Belt and Road". The improvement of port efficiency provides a strong support for the high-quality development of the "Belt and Road". Based on the export data of 11 coastal provinces and cities in China to countries along the "Belt and Road", the gravity model is used to empirically test the impact of port efficiency on the dual margin of exports. Studies have shown that there are large differences in port efficiency among China’s coastal provinces and countries along the "Belt and Road";the improvement of port efficiency can significantly promote the dual margin of China’s exports to countries along the "Belt and Road";The promotion effect of port efficiency on the dual margin of industrial exports is greater than that of agricultural products;the influence of port efficiency on different regions of the "Belt and Road" has greater heterogeneity;After further controlling the endogeneity, it is found that the improvement of port efficiency of the countries along the route has a greater marginal effect on China’s extensive margin than the intensive margin.
