东北地区沿海港口铁路集疏运能力分析与提升研究OA

With the ongoing revitalization of Northeast China and the implementation of the national strategy to reduce logistics costs,the share of railway transport in the cargo collection and distribution systems of coastal ports in this region is expected to rise continuously.To identify the existing problems and propose effective railway service improvement measures,this study first reviewed the technical standards and capacity utilization status of the hinterland transport links serving six major ports(Dalian,Yingkou,Jinzhou,Huludao,Panjin,and Dandong).Based on this analysis,key issues in their railway-based collection and distribution systems were identified,including congestion in port-dedicated railways and hinterland corridors,outdated terminal facilities,and poor intermodal connectivity.Accordingly,three categories of enhancement measures were proposed:upgrading the capacity of port railway hinterland corridors,improving the service level of terminal facilities,and strengthening the coordination between ports and railways.The results can provide a valuable reference for optimizing railway services to support the revitalization of Northeast China and for advancing the regional"shift from road to rail"policy.
