摘要

由于国际海事组织制定了 2020 年低硫法规，航运公司纷纷采用极低硫燃料或洗涤器，从而改变了成本结构和竞争力。本研究通过建立两个航运公司在有和没有该法规情况下的博弈论模型，研究了该法规对低硫战略的影响。研究结果表明，虽然该法规对托运人不利，但对承运人和燃料供应商却可能有利。然而，在低竞争环境下，由于低硫要求，没有慢速蒸汽的承运商可能会陷入困境，从而最大限度地减少托运人的损失。这项研究旨在寻求一种均衡的低硫战略，发现速度并不总是能提高市场份额或利润。利用洗涤器可实现帕累托效率，避免其他战略中存在的囚徒困境。此外，最佳平衡可能会提高海运供应链的效益，从而强调了战略性采用低硫和遵守法规对于可持续竞争优势的重要性。

Has the low sulfur strategy benefited the maritime supply chain?

Owing to the IMO 2020 low sulfur regulation, shipping carriers have adopted either very low-sulfur fuels or scrubbers, altering their cost structures and competitiveness. This study examines the regulation’s impact on low sulfur strategies by building game theory model of two carriers under scenarios with and without the regulation. The results reveal that while the regulation can disadvantage shippers, it potentially benefits carriers and fuel suppliers. However, in low-competition contexts, the carrier without slow steaming might struggle due to the low sulfur requirement, thus minimizing shipper losses. The research aims for an equilibrium low sulfur strategy, uncovering that speed does not always enhance market share or profits. Utilizing scrubbers achieves Pareto efficiency, avoiding the prisoner’s dilemma present in other strategies. Furthermore, the optimal equilibrium may enhance maritime supply chain benefits, emphasizing the importance of strategic low sulfur adoption and regulatory compliance for sustainable competitive advantage.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
