Research Of Spatial Economic Structure And Optimization In The Jianghuai Urban Agglomeration

The Jianghuai Urban Agglomeration is not only the important region that thecountry clearly puts forward to the development, but also the strategic fulcrum ofeconomic leap of Anhui province and mid rise. Spatial economic structure is the mostgeneral structural features of the Urban Agglomeration. Spatial economic structure isthe certain aspects of understanding of the intrinsic properties. Only deeply researchon the space economic structure features, can Jianghuai Urban Agglomeration realizethe target of leaping development and driving Anhui economic to fly, leading midrise abruptly.Firstly, this paper describes the basic theory of economic structure of the groupspace. According to the different definitions of urban agglomeration, outlines thegeneral characteristics of the Urban Agglomeration. Meanwhile, through literaturereview and summarize define the connotation of the most universal and extensivespatial economic structure and the core contents: scale hierarchical structure,functional structure, spatial structure, economic ties structure.Secondly, it describes the overall pattern of Jianghuai Urban Agglomeration, andthe origin of the groups, the development significance, the composition of the city aswell as the basic economic conditions. Through comparing with the other UrbanAgglomerations find the economy status of the Jianghuai Urban Agglomeration.Through comparing with the developed Urban Agglomeration find the gap with thedeveloped areas. Through comparing with the mid Urban Agglomeration grasp theeconomic level in the same level of the Urban Agglomeration.Thirdly, it analysis the economic and structural characteristics of the JianghuaiUrban Agglomeration. After definition of the meaning of spatial economic structureand description of the research object, analysis the four aspects of the economicstructure of the Jianghuai Urban Agglomeration respectively. Using the first law of thecity, the urban agglomeration pyramid law and the rank-size rule to study the scalelevel structure characteristics, the results show that: the scale level structural featuresis quite reasonable, slow urban scale, low core cities of the first degree. Locationquotient, multivariate analysis method to analyze the functions of the structuralfeatures of the result: lower the urban agglomeration overall industrial level, industriallevel is not high, the advantage of the functions of convergence among cities,prominent functions weak. Based on fractal theory to study the spatial structurecharacteristics, the results show that: the concentric features, the first in the city is notobvious, the spatial structure of the urban agglomeration degree of balance is not high,the association between low levels of the city, the road transport network accessibilitylevel is not high. Social network analysis to study the structural characteristics ofeconomic ties, the results show that: the lower level of economic ties between the city,the core of economic development-the obvious edge, obvious differences in the theeconomic status between different cities.Finally, it proposed the optimal path to the economic structure of the JianghuaiUrban Agglomeration. Based on analysising of the structural characteristics of the space economy, in view of its inadequacy and problems，put forward the specificcountermeasures of optimization: reasonable construction of the grading scalestructure, constantly improve the city rank structure, depth optimize the spatial layoutstructure, and continue to strengthen the structure of economic ties.
