From Green Port to Green Corridor: Managing Decarbonization Mismatch in Seaport–Dry Port Multimodal Systems under the Maritime Silk Road

Greener operations at a seaport do not necessarily produce a lower-carbon seaport–dry port corridor when connected infrastructure, freight services and governance arrangements are misaligned. This study examines decarbonization mismatch as a difference in the readiness or compatibility of interdependent corridor components. Drawing on a bounded, purposive integrative reading of 26 cited scholarly publications, rather than an exhaustive systematic database review, it develops a four-dimensional Decarbonization Alignment Framework covering energy/infrastructure, modal/service organization, institutions/standards, and investment/incentives. The framework is translated into a four-state diagnostic matrix, provisional screening rules and a six-stage management roadmap. A fully hypothetical sequence involving Ningbo–Zhoushan, Zhejiang inland nodes and Central Asia/Uzbekistan explains how managers might distinguish interacting constraints; no current corridor performance is measured. The proposed Decarbonization Mismatch Index and Transition Readiness score separate readiness gaps from overall transition level, but neither measures actual emissions reduction. The contribution is a theory-informed, transparent starting point for cross-node diagnosis. Future research should test the indicators, thresholds, carbon outcomes and governance choices with observed corridor data.
