本研究は、Eurostatの指標を用いて2015～2023年の欧州諸国の持続可能な海運物流への移行パターンを分析。PCAとクラスタ分析により、単一の移行経路ではなく、エネルギー転換、モーダル統合、循環経済、環境持続可能性に関連する複数の異なる経路が存在することを明らかにした。政策立案や戦略計画に有用なベンチマーキング枠組みを提供する。
English
This study analyzes transition patterns towards sustainable maritime logistics in European countries from 2015-2023 using Eurostat indicators. PCA and cluster analysis reveal multiple differentiated pathways rather than a single homogeneous pattern, highlighting heterogeneity in energy transition, modal integration, circular economy, and environmental sustainability. The framework offers a transferable benchmarking tool for policy design and strategic planning.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、海運・物流分野の脱炭素化が課題であり、本分析の枠組みは日本の港湾・物流政策のベンチマークに応用可能。ただし、日本固有のデータは含まれておらず、参考程度の位置づけ。
In the global GX context
This paper contributes to global GX scholarship by providing a comparative framework for monitoring sustainable maritime logistics transitions, relevant to EU Green Deal objectives and potentially applicable to other regions. It emphasizes heterogeneous pathways, which is valuable for policy design beyond static rankings.

📄 Abstract（原文）
Background: Sustainable maritime logistics has become a strategic priority for achieving the European Green Deal objectives and accelerating the transition towards low-carbon and resource-efficient transport systems. Nevertheless, existing studies mainly focus on isolated sustainability dimensions, providing limited evidence on the heterogeneous transition patterns followed by European countries. This study proposes an integrated analytical framework to identify and characterise longitudinal transition patterns towards sustainable maritime logistics across Europe. Methods: A harmonised database was developed using Eurostat indicators covering European countries for the period 2015–2023. Following data preprocessing, missing-value treatment and standardisation, Principal Component Analysis (PCA) was employed to reduce dimensionality, while cluster analysis was applied to identify groups of countries sharing similar sustainability and logistics transition characteristics. Results: The proposed framework reveals that the transition towards sustainable maritime logistics does not follow a single homogeneous pattern but multiple differentiated pathways. The analysis identifies distinct country profiles associated with energy transition, modal integration, circular economy performance and environmental sustainability, highlighting heterogeneous convergence dynamics throughout the study period. Conclusions: The findings provide a robust and transferable benchmarking framework for monitoring sustainable maritime logistics transition at the European level. By identifying differentiated transition pathways rather than static rankings, the proposed approach offers valuable evidence for supporting strategic planning, policy design and decision-making aimed at accelerating the transformation of maritime logistics systems towards sustainability.
