Study On The Spatial Structure Characteristics And Its Driving Factors Of Harbin-changchun City Cluster Under The Perspective Of Multiple Flow

Globalization of economic development,information network reconstruction have provided the foundation and power for the connection between cities.City cluster has also gradually become the most promising development potential and economic vitality space for all countries in the world because it carries the important means of production or a large number of people in national development.Lement integration and resource sharing through capital flow,traffic flow,logistics and information flow among cities.The interaction of multiple streams between cities has brought great vitality and potential to the comprehensive development of urban agglomeration.It can break through the limitations and show the connection between the cities.Harbin-Changchun city cluster is an important measure to revitalize the old industrial base in northeast China and promote regional economic development.It is also the first of the national second-class city agglomeration and one of the important urban agglomerations in northeast China.Studying the spatial structure of Harbin-Changchun city cluster under the perspective of multiple flow will help to improve the problems of the urban agglomeration themselves and better integrate into the development process of the 14 th Five-Year Plan.This paper focuses on the formation of flow space,urban agglomeration spatial structure and flow space of the domestic and foreign literature review,analyzes the research and practice,on the existing research and practice,the convection space,multiple flow,urban agglomeration spatial structure concept,for the analysis of urban spatial structure laid the theoretical foundation.Second,respectively from the capital flow,traffic flow,logistics,information flow and composite flow perspective to construct the long urban agglomeration spatial structure network,from individual to local to the whole,the urban node centrality,urban connection strength and direction characteristics and urban hinterland characteristics,namely the quantitative analysis of "point-line-surface" dimension,in the 2010-2019,on the basis of numerical change trend analysis,the 2010,2019.The study found that from the perspective of multiple flow,the urban agglomeration takes Changchun and Harbin as "double cores",forming a structure with low connection level and unbalanced distribution of spatial connection.The connection between the two provinces is less and the coordination level is relatively low,and the overall and local connection of different cities need to be further strengthened.Then,the long urban agglomeration spatial structure driving index selection,index system construction,combining qualitative and quantitative analysis illustrates the point,line,surface level long urban agglomeration drivers of spatial structure,found the long urban agglomeration point,line,surface level of transportation level,infrastructure construction,industrial development level,economic development level.The above driving factors are combined with the imbalance of hierarchical structure,weak node strength,scattered spatial linkage,inefficient urban connection,serious industrial homogeneity,insufficient radiation capacity and other industries.Specifically,combined with the actual development of the cities,from the hierarchical structure,strengthen the overall strength,enhance the line element strength,expand the scope of radiation,in order to improve the spatial situation of the urban structure to provide reference.
