    随着“一带一路”倡议的推进，中国与“一带一路”沿线国家的外贸总值逐渐加大，与“一带一路”区域的外贸格局呈现多样化，西部地区在我国与“一带一路”沿线国家的经济往来中，发挥着更加重要的作用，西部省份与沿线国家的经济往来也日益频繁。在新一轮西部大开发的背景下，要充分融入“一带一路”建设，加强西部地区与“一带一路”区域的贸易交往，通过商品流通为西部地区有效拓展国际市场，对西部省份的经济和社会发展具有重大意义。

   基于西部地区与“一带一路”沿线国家商品流通的现状，运用DEA方法对西部地区的商品流通效率进行评价，发现西部地区2011-2019年间商品流通的效率有所提升，但整体发展效率依旧低下且西部地区区域发展差异大；在以上实证测度的结果上分析造成西部地区的综合效率不高的原因是各省份技术效率低下，基础效率DEA无效。针对上文分析，提出以下建议：第一，完善区域内综合交通运输通道；第二，提升区域内信息技术水平；以此提升西部地区的商品流通效率，促进西部地区的经济发展。

With the advance of the “Belt and Road” initiative, China’s trade with the countries along the “Belt and Road” has gradually expanded in scale and diversified in pattern, the western region is playing an increasingly important role in the economic cooperation between China and the countries along the “Belt and Road”, and the trade between the western region and the countries along the route is also increasing. In the context of the new round of development of the Western Region, we should give full play to the leading role of “Belt and Road”construction, strengthen trade exchanges between the western region and the countries along the route, and effectively expand international markets for the western region through the circulation of commodities, it is of great significance to the economic and social development of the Western Region.

Based on the current situation of commodity circulation in the western region and the countries along the “Belt and Road”, this paper evaluates the efficiency of commodity circulation in the western region by using DEA method, and finds that the efficiency of commodity circulation in the western region has improved from 2010 to 2019, however, the overall development efficiency is still low and there is a big difference in the regional development of the Western Region. Based on the results of the above empirical measurement, the reason for the low overall efficiency of the western region is the low technical efficiency of the provinces and the inefficiency of scale efficiency DEA. In the light of the above analysis, the following recommendations are made: First, we should improve the comprehensive transportation channels in the region. Second, we should improve the level of information technology in the region so as to improve the efficiency of commodity circulation and promote the economic development of the western region.
