港口当局的主要目标是,运营商,而投资者则是实现高效运营和有效环保。这是因为集装箱港口的环境性能对于其竞争力和可持续发展至关重要。然而,随着海上丝绸之路(MSR)的快速发展,其中最重要的问题是环境污染。在本文中,我们的目标是衡量和比较MSR沿线十个主要集装箱港口的环境表现和运营效率,包括上海港,香港,新加坡,Kelang,LaemChabang,科伦坡,迪拜,巴塞罗那,安特卫普,汉堡。我们开发了一种改进的,不可分离的数据包络分析(DEA)模型和基于松弛的措施(SBMs)来评估和比较环境绩效和运营效率,并且我们结合了容器吞吐量的期望输出以及CO2排放的不期望输出。我们的结果表明。总体而言。这些集装箱港口在运营效率方面的表现优于环境表现。我们还为具有不同运营效率和环境绩效水平的集装箱港口的管理层和政策制定者提供见解。
A major goal for port authorities, operators, and investors is to achieve efficient operations and effective environmental protection. This is because the environmental performance of a container port is important for its competitiveness and sustainable development. However, the container ports along the Maritime Silk Road (
MSR) have caused numerous problems with the rapid development, among which the most significant problem is environmental pollution. In this paper, we aim to measure and compare the environmental performance and operational efficiency of ten major container ports along the
MSR, including the ports of Shanghai, Hong Kong, Singapore, Kelang, Laem Chabang, Colombo, Dubai, Barcelona, Antwerp, and Hamburg. We develop an improved, inseparable data envelopment analysis (DEA) model with slack-based measures (SBMs) to evaluate and compare the environmental performance and operational efficiency, and we incorporate the desirable output of container throughput as well as the undesirable output of CO2 emission. Our results show that. Overall. these container ports perform better in terms of operational efficiency than environmental performance. We also provide insights for management and policy makers for container ports with different levels of operational efficiency and environmental performance.
