The goal of this study is to analyse the efficiency and profitability performance of Spanish ports of general interest over the 2011–2018 period. The approaches adopted so far do not include both variables. It is based on our own original methodology, defining and calculating different ratios for each port and its clusters according to size, geographical location and cargo specialisation.

The paper culminates in relevant findings in terms of the qualitative nuances involved in identifying the most efficient and profitable groups of Spanish Port Authorities, which will be of value to policy makers.

西班牙港口是否高效且有利可图？定量分析

这项研究的目的是分析2011-2018年西班牙感兴趣的西班牙港口的效率和获利能力表现。到目前为止，所采用的方法并未同时包含这两个变量。它基于我们自己的原始方法，根据规模，地理位置和货物专业化为每个港口及其集群定义和计算不同的比率。

本文的最终结论是在确定西班牙港口当局最有效和最有利可图的群体方面所涉及的定性差异，这将对决策者有价值。
