Research On Coupling And Synergy Of Railway Transportation And Logistics In Consumption-based Megalopolises

In recent years,with the development of economy and society,urban consumption has been continuously upgraded.However,urban logistics has shown many disadvantages while it benefits from economic development.The limitations of the existing organizational model and the limited stock of logistics resources have gradually hindered the healthy development of urban logistics and even the city,and many drawbacks need to be improved urgently.Especially,the real problems are more obvious in the consumption-based megalopolises.However,the development dilemma of urban logistics coincides with the basic situation of railway transportation stagnation.In the current development period,the benefits of a single development model are limited,and the integration of development will become an inevitable trend.The coordinated development of railway transportation and urban logistics will be an effective way to break through the predicament,while the consumption-based megalopolises provide a powerful platform for the coordinated development of them.Based on this,the coupling relationship between railway transportation and urban logistics has been analyzed in the background of the consumption-based megalopolises,and the system,coupling railway freight yard with urban logistics distribution,has been clarified as a coupling form between railway transportation and urban logistics.Meanwhile,the railway freight yard system and urban logistics distribution system are analyzed from the aspects of elements,structure and environment,and the coupling relationship between the two systems has been probed from the holistic perspective.Then this paper expounds the basis and power source of the coupling system,with analyzing the elements,structure,environment and function orientation of the coupling system.And the coordinated development path of coupling system has been discussed based on Hard System Methodology.Furthermore,the evaluation index system of the coupling coordinative degree is introduced on the basis of the coupling relationship among elements,network and environment of the coupling system.Then the coupling theory model based on set pair analysis is established by using Set Pair Analysis Theory,Rough Set theory and System Coupling Theory,which can quantitatively analyze the adaptability of using railway freight yard resources to serve urban logistics distribution.Finally,Beijing is taken as an example,which is a typical consumption-based megalopolises.Three typical railway freight yards in this city are selected as the object of analysis and the adaptability of using railway freight yard to serve urban logistics distribution is analyzed based on the evaluation method system proposed in this paper.The result shows that the model is validity,and the path of collaborative development between the three railway freight yards and urban logistics distribution is also analyzed from a realistic point of view.At last,considering the reality in a comprehensive way,some countermeasures and suggestions are put forward to promote the coordinated development between railway freight yard system and urban logistics distribution system,which can provide reference for industry development and urban management.
