港口腹地海铁联运车站的辐射范围分析方法与应用OA

To support precise marketing for railway transportation enterprises and promote the development of rail-sea intermodal transport,a research method was proposed that combines the Generalized Cost Theory and GIS network analysis technology to study the radiation range of railway stations.Using the examples of Fuzhou Port and Xiamen Port in Fujian Province,the radiation range of rail-sea intermodal stations in the hinterland of these two ports were analyzed.Based on this,the effectiveness of Xiamen Port's sea-rail intermodal subsidy policy was assessed from the perspective of changes in radiation range and changes in the share of sea-rail intermodal transport.The results show that the radiation range of railway stations in the hinterland of Xiamen Port and Fuzhou Port is 20～45 km and 20～80 km respectively.Financial subsidies can effectively promote the development of sea-rail intermodal transport at Xiamen Port,manifested by a significant increase in the radiation range of sea-rail intermodal stations in Xiamen Port's hinterland and an approximate 6.22% increase in the share of sea-rail intermodal transport in the study area.However,financial subsidies also bring about issues of fierce competition between neighboring ports in terms of railway freight sources,as approximately 30.96% of Xiamen Port's sea-rail intermodal growth results from the transfer of railway freight sources from Fuzhou Port.
