本論文は、米中対立下でもロサンゼルス・ロングビーチ・上海グリーン海運回廊が協力を維持できる理由を政治経済学の視点から分析する。制度的隔離と交渉による漸進主義という概念を提示し、岸壁電力や代替燃料の実証実験などの初期成果を評価する一方、燃料価格変動や資金不足が規模拡大を阻むと指摘する。
English
This paper analyzes how the LA–Long Beach–Shanghai green shipping corridor sustains cooperation despite US-China tensions, introducing concepts of institutional insulation and negotiated gradualism. It finds early milestones in shore power and alternative fuels but notes that fuel price volatility and financing gaps limit scale-up.

日本のGX文脈において
日本は海運大国であり、グリーン海運回廊の国際協調の枠組みは、日本の港湾・海運企業の脱炭素戦略に示唆を与える。また、米中対立下での協力維持メカニズムは、日本の国際的な気候外交にも参考になる。
In the global GX context
This paper contributes to global GX scholarship by examining green shipping corridors as governance experiments under geopolitical tension, offering concepts applicable to other international decarbonization initiatives. It highlights the role of subnational actors and industry in advancing climate goals despite national-level conflicts.

📄 Abstract（原文）
Maritime shipping accounts for approximately 2.9% of global anthropogenic greenhouse-gas emissions, and green shipping corridors have emerged as route-specific governance experiments intended to accelerate decarbonization. This paper examines how stakeholders sustain cooperation on a zero-emission shipping corridor under acute geopolitical tension. Using a qualitative case study of the Los Angeles-Long Beach-Shanghai Green Shipping Corridor between 2022 and 2025, the analysis draws on collective-action theory, regime-formation theory, and complex interdependence, and engages recent scholarship on polycentric and multi-stakeholder ocean governance to develop two analytical concepts, institutional insulation and negotiated gradualism. Evidence is drawn from a documented corpus of partnership reports, port and government records, primary trade-policy documents, and independent regulatory, corporate, and trade sources; key empirical claims are triangulated against non-partnership sources and flagged where they rest on partnership reporting alone. Subnational and industry actors sustain operational cooperation even as U.S.-China relations deteriorate, achieving early milestones in shore-power deployment, alternative-fuel voyages, and standardized reporting, while fuel-price volatility, infrastructure-financing gaps, and unequal bargaining power confine activity to demonstration scale. Institutional insulation describes the deliberate channeling of cooperation into bounded technical workstreams to shield progress from national-level geopolitical disruption, with observable indicators that distinguish it from cooperation that merely happens to remain technical and the conditions under which it is expected to fail. Negotiated gradualism characterizes the pattern whereby stakeholders sustain incremental commitments through mutual commercial interest while structural asymmetries in bargaining power, cost distribution, and fuel-market conditions constrain systemic transformation. To the authors’ knowledge, the paper provides the first political-economy analysis of a green shipping corridor operating under acute geopolitical tension, and it specifies scope conditions under which its mechanisms are expected to travel to other cases.
