This paper aims to assess the efficiency of Irish and North Atlantic Spanish ports in generating traffic and examine changes in efficiency over the period 2000-15. Specifically, technical efficiency scores are derived by using stochastic frontier analysis. Subsequently, cluster analysis is employed to develop a robust typology of ports for efficiency benchmarking. This paper has identified two clusters of ports with the estimated average technical efficiency of cluster 1 ports being much higher than the efficiency of cluster 2 ports. Differences in efficiency and main characteristics of clusters have persisted during the period 2000-15.

爱尔兰和北大西洋西班牙港口的效率基准：对蓝色增长的影响


本文旨在评估爱尔兰和北大西洋西班牙港口在产生交通方面的效率，并研究 2000-15 年期间效率的变化。具体来说，技术效率得分是通过使用随机前沿分析得出的。随后，采用聚类分析来开发强大的端口类型以进行效率基准测试。本文确定了两个港口集群，集群 1 港口的估计平均技术效率远高于集群 2 港口的效率。 2000-15 年期间，集群的效率和主要特征仍然存在差异。
