Abstract:

Cargo flow reflects the economic ties and spatial interaction among different region unites, which helps to probe the economic networks. Based on comment on research progress of railway cargo, we constructed the GIS data base of railway cargo flow in China since 1950s, and analyzed its spatial regularity (including the distribution and flow configuration), its evolution and flowing path. We drew these conclusions: (1)With more and more cities tied by railway, the covering scope and interaction density of railway cargo has been expanded, urging interregional economic ties to expand from interior to exterior and develop the cooperating networks. (2)There is a zoning character of cargo distribution with different scales in East, Middle and West Regions or in North and South Regions, but with weakening trend. North China became their central region. Additionally, resource regions and several transport hubs became the main outflow region of cargo, but industrial regions and many transport hubs became the main inflow region.(3)Due to concentrative transportation of cargoes, trunk railways have the great amount of cargo flow and density which developed into transportation way and compete the interregional economic ties and their adjacent regions with a great scale of railway cargoes which developed into the cargo belt.(4)Cargo flow occurred largely in East and Middle Regions or North Regions, and most are lognitudinal and some are transmeridional but with increasing trend.(5)There occurred the polarization of cargo flow, and some urban clusters (especially capital regions) became the concentrative regions of railway cargo and flow, but some cities or regions, due to the resource distribution and transport location, became the flowing hub, and (6)Cargo flow between resource cities and ports or industrial regions became increasingly important, but container flow occurred among the regional central cities. Those discussions help to probe the interregional economic ties and urban spatial interaction.
