港口服务业逐年发展，在各国经济和运输市场中发挥着越来越重要的作用。这增加了人们对衡量他们表现的兴趣。本文利用稳健的非参数方法对一组欧洲海港的性能进行了评估。利用阶数m和Bootstrap过程，克服了传统数据包络分析和自由处理方法的主要问题--噪声、孤立点的存在和“维度诅咒”。这项研究发现，欧洲海港部门的效率相当低。
Abstract Seaport services have been developing year on year, playing an increasingly important role in the economy and the transportation markets of each country. This increases interest in measuring their performance. This paper evaluates the performance of a set of European seaports by means of robust non-parametric approaches. Using order-m and bootstrap procedures, the major problems of traditional data envelopment analysis and free disposal hull methods – concerning noise, presence of outliers and the ‘curse of dimensionality’ – are overcome. With this study considerable levels of inefficiency were found in the European seaports sector.
