Abstract

This paper aims to assess container terminal (CT) efficiency with the effect of carbon neutrality. Among mechanisms to achieve carbon neutrality in CTs' operations, emission taxes are deemed the most preferred tool to internalize the external costs associated with greenhouse gas emissions by placing a financial burden on polluters. This paper first uses cluster analysis to determine the homogeneous decision-making units (DMUs), i.e., container terminals. A novel approach is proposed to determine the level of emission taxes that DMUs should be levied based on how much CO2 they discharge. Since emission taxes are an undesirable output from the operations of CT operators (CTOs), the Slacks-based Measure Data Envelopment Analysis (SBM-DEA) model is thus employed to incorporate the emission taxes into the research model and to determine the optimal emission taxes for CTOs. Finally, the CTOs in Vietnam (hereafter the VN-CTOs case) are empirically surveyed to verify the proposed model. The proposed research framework can contribute a methodological reference toward the relevant literature in achieving carbon neutrality. Further, the empirical results can provide practical information for the Vietnamese CTOs to improve their CT efficiency.

从碳中和角度评估越南集装箱码头效率

本文旨在评估集装箱码头（CT）在碳中和效应下的效率。在实现集装箱码头运营碳中和的机制中，排放税被认为是最可取的工具，它通过对污染者施加经济负担，将与温室气体排放相关的外部成本内部化。本文首先利用聚类分析确定同质决策单元（DMU），即集装箱码头。本文提出了一种新颖的方法，根据 DMU 的二氧化碳排放量确定其应征收的排放税水平。由于排放税是集装箱码头运营商（CTO）运营过程中产生的不良产出，因此采用了基于斯拉克斯的计量数据包络分析（SBM-DEA）模型，将排放税纳入研究模型，并确定集装箱码头运营商的最优排放税。最后，对越南的 CTO（以下简称 VN-CTO 案例）进行了实证调查，以验证所提出的模型。所提出的研究框架可为实现碳中和的相关文献提供方法论参考。此外，实证结果可为越南 CTO 提高碳中和效率提供实用信息。

期刊介绍： Utilities Policy is deliberately international, interdisciplinary, and intersectoral. Articles address utility trends and issues in both developed and developing economies. Authors and reviewers come from various disciplines, including economics, political science, sociology, law, finance, accounting, management, and engineering. Areas of focus include the utility and network industries providing essential electricity, natural gas, water and wastewater, solid waste, communications, broadband, postal, and public transportation services. Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
