Focusing on the chain-like connections and co-evolution among multiple actors, resource elements, and operational links within the transportation system, this study explores design intervention mechanisms aimed at sustainable mobility. From an ecological chain perspective, it examines the coupling relationships among transportation modes, energy supply, shared last-mile connections, information service platforms, and terminal microcirculation facilities, emphasizing system optimization in terms of node linking, flow regulation, and value circulation. Methodologically, it integrates service design, business ecosystem theory, and dynamic network modeling to analyze inefficient closed loops and broken links, proposing iterative and scalable design strategies. Through prototype experiments and scenario simulations, it promotes the resilience reconstruction and low-carbon transformation of the transportation ecological chain at both urban and rural scales.
