“一带一路”建设5年来，中国与沿线国家之间的贸易合作水平逐渐提高。从贸易额和贸易占比看，中国对“一带一路”沿线国家的出口占总出口的比重呈持续上升趋势，自沿线国家的进口则受大宗商品价格波动的影响，呈现波动特征。从贸易结构看，产业间贸易是中国与“一带一路”沿线国家贸易的主要结构特征，但与东南亚国家之间则表现出较明显的产业内贸易特征，显示中国与这些国家和地区的产业内分工水平较高，更高的贸易额也是这种分工的表现。相对而言，中东欧国家尽管工业化水平较高，但与中国的产业间贸易特征表明，中国与这些国家之间还缺乏产业内分工合作。“一带一路”沿线国家贸易合作的发展还表现在贸易便利化的进展方面，其中，沿线自贸区建设是推进贸易便利化的重要手段。
Since the Belt and Road Initiative was proposed five years ago，trade cooperation between China and the countries involved has been boosted gradually.According to the trade value and proportion，the ratio of China’ exports to the countries along the Belt and Road to the total exports is continuously growing while the ratio of imports from these countries fluctuates due to the fluctuation of the prices of staple commodities.In terms of the trade structure，inter-industry trade is the main structural feature between China and the Belt-and-Road countries，while it features obvious intra-industry trade between China and Southeast Asian countries.This shows a higher level of labor division within industry between China and the countries along the Belt and Road，which accounts for the higher trade value.Relatively speaking，central and eastern European countries are more industrialized，but the industrial trade with China demonstrates a lack of intra-industrial labor division and cooperation.The development of the cooperation with the countries along the Belt and Road is still limited to the progress in trade facilitation and the construction of free trade zones which is the main measure taken to promote trade facilitation.
