本論文は、港湾と海運会社の協調的排出削減について、垂直的技術スピルオーバーと共同利益・費用分担を考慮した進化ゲームモデルとスケールフリーネットワークを用いて分析。港湾が脱炭素化のリーダーとして機能し、適度なスピルオーバー強度が最も高い参加意欲をもたらすこと、港湾中心の資源配分が重要であることを示した。
English
This study analyzes collaborative decarbonization between ports and shipping companies, incorporating vertical technology spillovers and joint benefit-cost sharing. Using an evolutionary game model combined with a scale-free network, it finds that ports act as leaders and that moderate spillover intensity maximizes active emission reduction adoption. Port-centered resource allocation is key to system-wide low-carbon transition in maritime supply chains.

📄 Abstract（原文）
Collaborative decarbonization between ports and shipping companies is critical to the low-carbon transition of maritime supply chains. Driven by the new energy transition, vertical technology spillovers have become a key force shaping vertical collaborative emission reduction. However, the mechanisms through which spillovers affect strategic interactions remain unclear, the theoretical basis for emission reduction strategies is insufficient, and practical issues such as benefit sharing and coordination mechanisms are underexplored. To fill these gaps, this study makes three contributions. Theoretically, we incorporate vertical technology spillovers and joint benefit–cost sharing into the port–shipping collaborative emission reduction framework, enriching supply-chain-level spillover theory. Methodologically, we combine an evolutionary game model with a scale-free network to simulate strategy diffusion and conduct scenario comparisons, linking theoretical modeling with industrial practice. Empirically, we confirm that ports act as leaders in collaborative decarbonization, and port-centered resource allocation drives the systemic low-carbon transition of the maritime sector. The findings show that the share of agents adopting active emission reduction strategies first rises and then falls with vertical technology spillover intensity, peaking at a moderate level. The impacts of core factors vary significantly across spillover scenarios. Port-centered resource allocation and benefit distribution are crucial to improving overall participation willingness. Ports are not merely participants but irreplaceable coordinators in the maritime supply chain. These results provide targeted policy and practical guidance for ports and shipping companies to promote global green and low-carbon maritime development.
