Research On The Logistics Spatial Difference Of Shandong Peninsula And East Liaoning Peninsula Urban Agglomeration On The Construction Of Trans-Bohai Strait Passageway From "Space Of Flows"

In the age of globalization,people pay close attention to "space of flows" and its factors.The transportation network has become an important system to support globalization and promote the flow of transnational capital,trade,personnel and products.The Trans-Bohai Strait Passageway is an important strategic channel for the Bohai economic circle and the coastal areas of eastern China,which has a profound influence on the inter-regional logistics communication and the integration of urban agglomeration.Based on the theory of "space of flows" perspective,this study associated logistics space and the construction of the Trans-Bohai Strait Passageway.The main line of this study is the difference of logistics space between Shandong peninsula and Liaodong peninsula agglomeration before and after the completion of channel construction.While expanding and deepening the theoretical content spectrum of "space of flows",it reveals the heterogeneous response of the hub transportation project to the flow of the factors of urban agglomeration.It is expected to provide reference for early research and demonstration of Trans-Bohai Strait Passageway.This research is divided into 5 chapters: The first chapter introduces the background significance of the research,the main theory and the research area.It systematically sorts out the domestic and foreign research achievements such as "space of flows" and its factors,logistics space network and trans-river/sea channel,etc.And it provides theoretical and practical guidance for this research.In addition,a top-level design was made for the technical route and research scheme of this article.Chapter 2 elaborates the comprehensive research methods used in the article,including the traffic accessibility measures of urban agglomeration before and after the construction of the Trans-Bohai Strait Passageway,the construction of output data flow index model and the combination of social network analysis method.The clarification of its content directly determines the authenticity and credibility of the results of the logistics spatial difference of urban agglomeration.Chapter 3 and chapter 4 are the key chapters of this study.Based on the exchange of logistics between the Shandong peninsula and the Liaodong peninsula urban agglomeration,it strengthens the discussion on the characteristics of "liquidity","orientation" and "relationship".By means of accessibility,centrality,maximum contact flow and network density method,it separately researches the urban agglomeration road and the railway logistics space before and after the completion of the Trans-Bohai Strait Passageway,then it finds out:(1)The influence of the Trans-Bohai Strait Passageway construction on traffic accessibility is mainly concentrated on the top areas of Shandong peninsula and Liaodong peninsula urban agglomeration.And it is even not economical for the distant city.(2)After the completion of the Trans-Bohai Strait Passageway,the logistics communication of the passageway is generated,therefore,the logistics spatial pattern has undergone fundamental changes.The internal logistics of urban agglomeration is much higher than that of inter-provincial communication.The construction of the Trans-Bohai Strait Passageway specially strengthens Dalian's logistics radiation ability to the Shandong peninsula,and Yantai,Qingdao and Weifang's to the Liaodong peninsula,while maintaining the reciprocity of logistics concentration and radiation.The maximum contact flow pattern of the passageway is complicated.The main shaft of highway logistics in Dalian-Yantai-Qingdao is basically formed.(3)The density of the logistics space before and after the completion of the bohai channel has changed.In 2050,the logistics of land transportation will continue to dominate.The logistics communication of the passageway mainly occurs between Dalian,Qingdao,Yantai,Weifang and other local key cities,but distant cities are gradually "marginalized" in network structure.Chapter 5 is the conclusion and prospect.It points out the advantages of "space of flows" theory and SNA method in analyzing the spatial pattern of flow factors,summarizes the traffic accessibility and the heterogeneity of logistics in "node" "connection" and "network" and discusses the innovation of the article and the key issues that should be paid attention to in the future in the end.
