本論文は、世界の石炭と石油の価値ネットワークを構築し、過去24年間の特性と回復力を評価。主要国としてサウジアラビアやイスラエルが貿易ネットワークの中心だが、価値ネットワークでは異なる。ロシアは価値流量で2位だが、ノード重要度では15位。ネットワークは回復力を示し、米国とロシアへの攻撃の影響は減少後増加。エネルギー安全保障政策に示唆を与える。
English
This paper constructs a global coal and oil value network, evaluating its evolutionary characteristics and resilience over 24 years. Key findings: Saudi Arabia and Israel are central in trade networks but not in value networks; Russia ranks second in value flow but 15th in node importance; the network shows positive resilience; attacks on the US and Russia show a declining-then-increasing impact. Insights for energy security and transition policy.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は石炭・石油の輸入依存度が高く、本論文の価値ネットワーク分析は供給途絶リスク評価やエネルギー安全保障政策立案に資する。特にロシアの位置づけ変化は、日本を含む主要輸入国の調達戦略に示唆を与える。
In the global GX context
The paper provides a novel network perspective on global fossil fuel value chains, complementing trade-based analyses. Its resilience metrics are relevant for understanding energy security in a transitioning world, especially for countries reliant on coal and oil imports. The findings can inform transition policies that account for supply vulnerabilities.
👥 読者別の含意
🔬研究者:Offers a methodological framework for analyzing energy value networks and resilience, applicable to other commodities or green energy supply chains.
🏢実務担当者:Provides insights for energy procurement and supply chain risk management, particularly for companies dependent on coal and oil imports.
🏛政策担当者:Highlights the importance of network resilience for energy security and the differential roles of key countries; useful for shaping import diversification and emergency response strategies.
📄 Abstract（原文）
Compared with conventional trade networks, the global coal and oil value network provides deeper insights into the competitive capabilities of various countries in the industry. Hence, measuring the resilience of value networks can effectively reflect the authentic recuperative state of energy sectors across diverse nations amid external shocks, which is highly important for maintaining global energy security. This paper, therefore, presents a directed, weighted global coal and oil value network to measure its evolutionary characteristics over the past 24 years. Then, the network’s resilience and the influence of key countries are evaluated through simulated attacks. The main conclusions are as follows. In terms of network characteristics, countries such as Saudi Arabia and Israel, which hold central positions in the coal and oil trade network, do not stand out in the value network. Meanwhile, although Russia ranks second on the value flow scale, it ranks only 15th in comprehensive node importance. Additionally, based on the resilience measurement, the global coal and oil value network has shown positive resilience. Lastly, the impact of attacks on the United States and Russia on the network has exhibited a trend of initial decline followed by an increase. The relevant findings of this study can provide long-term practical references and ideological insights for the governance of global energy security and the formulation of energy transition policies.
