日本語

海運業の脱炭素化においてグリーン燃料への転換が重要だが、実際の意思決定を妨げる要因を韓国海運業を事例に分析。Best-Worst Methodを用いて5次元の評価枠組みを構築し、16人の専門家調査を実施。経済的要因（初期投資・燃料コスト）が最大の障壁であり、供給安定性や技術成熟度も影響する一方、政策要因の直接影響は限定的であることを示した。

English

This study analyzes barriers to green fuel adoption in shipping, using South Korea as a case. Applying the Best-Worst Method to expert surveys, it finds economic factors (initial investment, fuel costs) dominate, followed by supply stability and technology maturity, while policy factors have limited direct influence. Offers insights for policymakers to ease corporate transition concerns.

📄 Abstract（原文）

With the rapid green transformation of the shipping industry, green fuels are considered a crucial way to achieve shipping decarbonization. However, despite continuous technological advancements, shipping companies remain cautious about fuel transitions in their actual operations. Meanwhile, existing research focuses primarily on the technical feasibility of green fuels, while lacking specific analysis of the key obstacles faced by shipping companies in actual decision‐making. Therefore, analysis of the key factors hindering shipping companies from switching to green fuels is essential for the shipping industry. Based on this, this paper uses the South Korean shipping industry as a case study, constructing an evaluation framework encompassing five dimensions: environmental sustainability, social responsibility, regulatory governance, economic benefits, and technological support. Methodologically, this paper employs the Best‐Worst Method to quantify the importance of each evaluation factor. The study obtained a sample of 16 experts with extensive experience to identify and rank the key factors. The results show that economic factors dominate fuel transition decisions, with initial investment costs and fuel costs being the most significant obstacles. Furthermore, fuel supply stability, technological maturity, and infrastructure conditions also significantly impact shipping companies' green fuel transition decisions, while policy factors have a relatively limited direct influence on corporate decisions at the current stage. The findings not only contribute to a deeper understanding of energy transition decision‐making in the shipping industry but also provide important insights for policymakers to design targeted policy tools to reduce the concerns and hesitations companies face during the green fuel transition.
