贸易畅通和贸易潜力的发掘是＂一带一路＂战略的重点和基础。文章就中国对＂一带一路＂主要沿线国家的出口潜力和影响因素进行了考察,结果发现,在中国对外出口贸易扩张的过程中,贸易非效率显著存在,未来中国的出口贸易还有很大的提升空间和潜力,这一点对于＂一带一路＂沿线国家尤其如此。同时,影响中国出口贸易效率的因素包括出口市场的基础设施条件、通关手续的复杂度、进口关税水平、金融发展水平和出口市场政府效率等。基于以上结论,文章认为在促进中国对＂一带一路＂沿线国家出口贸易效率提高的政策选择中,贸易自由化与基础设施条件的完善是最为重要的政策方向。

英文摘要：

Trade facilitation and trade potential exploitation play a fundamental role in the Belt and Road strategy. This paper investigates the export potential and its determinants of the main Belt and Road countries. The empirical results suggest a significant existence of export inefficiency during China＇s export expansion, indicating the great potential of China＇s future exports. This conclusion holds especially for the Belt and Road countries. In terms of the determinants of China＇s export potential, the results suggest that infrastructure conditions, custom procedure, import tariff level, financial conditions and government efficiency are important in affecting China＇s export efficiency. Based on the conclusions, we argue that promoting trade liberalization and strengthening infrastructure conditions should be top priorities in future policy options.
