The China-Europe Freight Train (CEFT) serves as an important carrier and platform for international economic cooperation and international trade circulation between China and Europe. Since it worked, its actual operation and development have been affected by many factors, but the level of its actual operating efficiency and the main affecting factors of CEFT have been difficult to find, which has severely limited its sustainable development. Therefore, this paper scientifically selected the operation efficiency evaluation indicator system of CEFT and combined grey system theory, cross-efficiency method, and DEA to construct a new DEA evaluation model based on grey cross-efficiency, which can not only overcome the problem of ignoring the relative importance ratings of the evaluation indicator in the general DEA evaluation model and the traditional cross-efficiency DEA evaluation model but also more accurately evaluate the actual operation efficiency of CEFT. At the same time, based on the actual operating data of CEFT from 2011 to 2018 and the above new evaluation models, the CEFT’s operation efficiency was evaluated and tested by examples, showing that on the one hand, the grey cross-efficiency DEA evaluation model can more accurately evaluate the actual operation efficiency of CEFT than other traditional evaluation models; on the other hand, it is found that the “overseas cities,” “operating lines,” and “entry-exit nodes” are currently the main factors that limit the actual operation efficiency of CEFT and indicating improvement direction for the future efficient and sustainable development of CEFT.

基于灰色交叉效率DEA的中欧班列运行效率评价

中欧班列是中欧国际经济合作和国际贸易流通的重要载体和平台。自成立以来，其实际运营和发展受到诸多因素的影响，但其实际运营效率水平和CEFT的主要影响因素难以查明，严重制约了其可持续发展。因此，本文科学选取了CEFT的运行效率评价指标体系，结合灰色系统理论、交叉效率法和DEA，构建了基于灰色交叉效率的新的DEA评价模型，不仅可以克服通用DEA评价模型和传统交叉效率DEA评价模型中忽略评价指标相对重要性等级的问题，而且可以更准确地评价CEFT的实际运行效率。同时，基于CEFT 2011-2018年的实际运行数据和上述新评价模型，对CEFT的运行效率进行了评价和实例检验，一方面表明灰色交叉效率DEA评价模型可以比其他传统评估模型更准确地评估CEFT的实际运行效率；另一方面，发现“海外城市”、“运营线路、
