摘要

本研究的目的是评估竞争和环境因素对欧洲港口技术效率低下的影响，采用Simar和Wilson(2007)的两步方法。在第一阶段，非参数DEA方法(数据包络分析)为我们提供了比较9个欧洲国家的30个港口的效率得分的手段，这些港口被认为是最大的集装箱港口。在第二阶段，我们使用了截断的自举回归，以确定技术效率的决定因素。结果表明:港口间竞争激烈，导致投资过度，技术效率下降。

The impact of competition and environmental factors on technical inefficiency of European ports

The goal of this study is to assess the effects of competition and environmental factors on technical inefficiency of European ports using the approach in two steps of Simar and Wilson (2007). During the first stage, a non-parametrical DEA method (Data Envelopment Analysis) provided us with the means to compare efficiency scores of 30 ports related to 9 European countries, these ports deemed as the largest container ports. During the second stage, we have used a truncated bootstrap regression so as to identify the determinants of the technical efficiency. Results show that an intense inter-port competition leads to over-investment and a decrease in technical efficiency.
