本研究は、EUのCBAM導入を背景に、越境サプライチェーンにおける炭素コストの伝達メカニズムを定量的に測定するモデルを構築。鉄鋼・アルミ産業を事例に、政策ショックから段階的伝達、産業別調整までの三段階モデルを用い、高炭素産業での伝達弾力性が高いことや、越境物流・中間投入が重要ノードであることを示す。企業の炭素コスト管理とグリーンサプライチェーン強化への示唆を提供する。
English
This study constructs a three-stage quantitative model to measure carbon cost transmission in cross-border supply chains under the EU CBAM. Using steel and aluminum cases, it finds higher transmission elasticity in high-carbon industries and identifies cross-border logistics and intermediate inputs as key nodes. Offers countermeasures for enterprises to manage carbon costs and enhance green supply chain management.

📄 Abstract（原文）
With the implementation of the European Union’s Carbon Border Adjustment Mechanism (CBAM), green trade barriers have entered a phase of rigid cost constraints. The transmission of carbon costs within cross-border supply chains has become a central issue affecting the competitiveness of Chinese export enterprises. Integrating global value chain theory and system dynamics methodology, this study constructs a three-stage quantitative measurement model comprising ‘policy shock, stage-by-stage transmission, and industry-specific adjustment.’ This model deconstructs the transmission pathways of carbon costs across upstream and downstream supply chain nodes and cross-border interfaces, identifying key influencing factors such as policy intensity and industry characteristics. Using the steel and aluminum industries as cases for measurement and sensitivity analysis, the study finds that carbon costs exhibit evolutionary characteristics of ‘policy-triggered, stage-transmitted, and industry-amplified’ effects, with transmission elasticity significantly higher in high-carbon industries than in low-carbon industries. Cross-border logistics and intermediate inputs are identified as key nodes. Finally, the paper proposes countermeasures concerning accounting systems, coordination mechanisms, and policy adaptation to help enterprises manage carbon cost impacts and enhance green supply chain management capabilities.
