摘要

在过去的二十年中,轮辐系统极大地改变了港口部门战略投资决策的行为。转运大大改变了海运业的构成和吞吐量,因此,运力大大增加。本研究以地中海盆地33个集装箱码头的技术效率和规模效率为标准,对码头的经济效益进行了衡量和比较。我们选择了DEA(数据包络分析)方法来衡量经济表现,我们在一个时间点使用横截面数据作为基准。DEA不需要任何功能形式的说明。DEA作为一种非参数规划方法,有助于确定决策单元(DMU)的效率。这项工作的结果表明,58%代表规模技术效率的恒定回报,这一结果被分解为69%的纯技术效率和83%的规模效率,因此,研究结果表明,码头在整体技术效率方面存在不足。大多数终端的运营规模都在不断缩小。投资方面的战略决策是集装箱码头部门管理的主要利益。

Measurement and benchmark of economic performance in the Mediterranean port sector
Over the past two decades, the hub & spoke system has significantly changed the behavior of strategic investment decisions in the port sector. Transshipment has significantly changed the composition and throughput traffic for the maritime industry, as a result, capacity has largely increased. This work aims to measure and compare the terminal economic performance based on two criteria: technical efficiency and scale efficiency for 33 container terminals in the Mediterranean basin. We have opted for the DEA (Data Envelopment Analysis) method for the measurement of the economic performance and we have used cross-sectional data for the benchmark in one point of time. DEA doesn't require any specification of the functional form. DEA as a non-parametric programming approach helps in determining the efficiency of a DMU (Decision Making Unit). The findings of this work show that 58% represents the Constant Return to Scale Technical efficiency, this result is broken down into 69% for pure technical efficiency and 83% for scale efficiency, therefore, the findings show that terminals are suffering from a shortfall in terms of overall technical efficiency. Most terminals are operating on decreasing scales. Strategic decisions in terms of investment are of major interest to the management of the container terminals sector.
