本研究は、水素エネルギー政策のガバナンス構造を評価するための四次元枠組み（政策目標、政策強度、政策手段、政策主体）を提案し、エントロピー重み付けTOPSIS法を用いてG20諸国を比較分析した。結果、米国、英国、ドイツ、フランス、カナダ、日本が上位グループを形成し、政策主体と政策目標が国間差に強く寄与していることを示した。
English
This study proposes a four-dimensional governance framework (policy objectives, policy intensity, policy tools, policy subjects) to assess national hydrogen policy frameworks. Using entropy-weighted TOPSIS, it compares G20 countries, finding the US, UK, Germany, France, Canada, and Japan in the leading group, with policy subjects and objectives contributing most to cross-national differentiation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本が水素政策で上位グループに位置づけられたことは、国内の水素基本戦略や国際連携の方向性を再確認する材料となる。今後、日本の政策設計の強み（政策主体の明確さなど）を活かし、SSBJやGX実現に向けた具体的な施策との連動が期待される。
In the global GX context
This paper provides a replicable method for benchmarking hydrogen governance frameworks globally. For countries developing hydrogen strategies, it highlights the importance of clear policy objectives and engaged policy subjects, offering a structured tool for policy learning and coordination in the global energy transition.
👥 読者別の含意
🔬研究者:Provides a structured four-dimensional framework and a replicable quantitative method for comparative hydrogen policy analysis.
🏛政策担当者:Offers actionable insights on which policy dimensions drive cross-country differences, helping prioritize policy design elements in national hydrogen strategies.
📄 Abstract（原文）
Hydrogen energy has emerged as a strategic pathway for decarbonization, industrial transformation, and energy security across major economies. This study does not directly evaluate ex post policy outcomes. Instead, it develops a Four-Dimensional Governance Framework to assess the structural effectiveness and implementation-oriented capacity embedded within national hydrogen policy frameworks. The analysis examines G20 countries through four dimensions, namely policy objectives, policy intensity, policy tools, and policy subjects. Using the entropy weighted TOPSIS method, the study compares the relative coherence of hydrogen governance architectures across countries. The results show that countries such as the United States, the United Kingdom, Germany, France, Canada and Japan consistently rank among the leading group in the comparative evaluation, while other countries occupy intermediate or lower positions according to the composite index results. Policy subjects and policy objectives receive relatively higher weights in the empirical analysis, indicating their stronger contribution to cross-national differentiation within the constructed index. The study provides a structured basis for comparing hydrogen governance frameworks and offers a replicable method for future research linking policy design to implementation evidence.
