【摘要】：江淮地區(qū)是《全國主體功能區(qū)規(guī)劃》中明確提出的重點發(fā)展區(qū)域。江淮城市群區(qū)位優(yōu)勢明顯，，經濟發(fā)展勢頭強勁。安徽省要實現(xiàn)跨越發(fā)展，需要大力發(fā)展和重點江淮城市群�？臻g經濟結構是城市群最一般的特征，是認識城市群內在屬性的必然方面。對江淮城市群空間經濟結構特征進行深入研究具有重要價值。 本文首先闡述了城市群空間經濟結構基本理論。根據城市群的不同定義概括出城市群的一般性特征。同時，通過文獻的回顧和總結，界定出最具普遍性和廣泛性的空間經濟結構的概念及核心內涵：規(guī)模等級結構、職能結構、空間結構、經濟聯(lián)系結構。 其次，描述了江淮城市群總體格局。介紹了江淮城市群的由來、發(fā)展意義、組成城市以及基本經濟情況。并與其他城市群比較，了解江淮城市群在國內基本經濟地位，通過與發(fā)達城市群比較，發(fā)現(xiàn)與發(fā)達地區(qū)的經濟差距；通過與中部城市群比較，掌握其在同一級別城市群中的經濟水平。 再次，分析了江淮城市群空間經濟結構特征。在界定了空間經濟結構的內涵和描述了研究對象之后，分別對江淮城市群空間經濟結構的四個方面進行了實證分析。采用城市首位律、城市群金字塔規(guī)律和位序—規(guī)模法則研究了規(guī)模等級結構特征，結果顯示：規(guī)模等級結構特征不盡合理、城市規(guī)模擴大速度緩慢、核心城市首位度偏低。采用區(qū)位商法、多變量分析法對職能結構特征進行了分析，結果表明：城市群整體產業(yè)水平較低，產業(yè)層次不高、各城市間優(yōu)勢職能趨同，突出職能薄弱。根據分形理論研究了空間結構特征，結果表明：首位城市的向心性特征不明顯、城市群空間結構均衡性程度不高、城市之間關聯(lián)水平較低，公路交通網絡通達性水平不高。采用社會網絡分析法研究了經濟聯(lián)系結構特征，結果表明：城市間經濟聯(lián)系水平較低、經濟發(fā)展核心—邊緣特征明顯、各城市經濟地位差異明顯。 最后，提出了優(yōu)化江淮城市群空間經濟結構的路徑。在分析了空間經濟結構特征的基礎上，針對其不足與問題之處，提出了具體的優(yōu)化對策：合理構建等級規(guī)模結構、不斷完善城市職能結構、深入優(yōu)化空間布局結構、繼續(xù)加強經濟聯(lián)系結構。
[Abstract]:The Jianghuai area is the key development area clearly proposed in the National Major functional area Planning. The location advantage of the Jiang-Huaihe urban agglomeration is obvious, and the economic development momentum is strong. The spatial economic structure is the most general feature of the urban agglomeration and the inevitable aspect of understanding the inherent attributes of the urban agglomeration. It is of great value to study the spatial economic structure characteristics of the Jiang-Huai urban agglomeration. This paper first expounds the basic theory of spatial economic structure of urban agglomeration, and generalizes the general characteristics of urban agglomeration according to different definitions of urban agglomeration. This paper defines the concept and core connotation of the most universal and extensive spatial economic structure: scale hierarchy structure, functional structure, spatial structure and economic connection structure. Secondly, it describes the overall pattern of Jianghuai urban agglomeration, introduces the origin, development significance, composing city and basic economic situation of Jianghuai urban agglomeration, and compares with other urban agglomerations to understand the basic economic status of Jianghuai urban agglomeration in China. By comparing with the developed urban agglomeration, the economic gap with the developed regions is found, and the economic level of the urban agglomeration at the same level is grasped by comparison with the central urban agglomeration. Thirdly, it analyzes the characteristics of the spatial economic structure of the Jianghuai urban agglomeration, after defining the connotation of the spatial economic structure and describing the research object, Four aspects of the spatial economic structure of the Jiang-Huai urban agglomeration are empirically analyzed. The characteristics of the scale hierarchy structure are studied by using the law of city primacy, the law of urban agglomeration pyramid and the law of location-scale. The results show that the characteristics of scale grade structure are unreasonable, the expansion speed of city scale is slow, the first degree of core city is low, and the function structure characteristic is analyzed by using location quotient method and multivariate analysis method. The results show that the overall industrial level of the urban agglomeration is low, the industrial level is not high, the dominant functions of different cities converge, and the prominent functions are weak. According to the fractal theory, the characteristics of spatial structure are studied, and the results show that the centericity of the first city is not obvious. The spatial structure of urban agglomeration is not well balanced, the level of correlation between cities is low, and the accessibility level of highway traffic network is not high. This paper studies the characteristics of economic connection structure by means of social network analysis. The results show that the level of economic relationship between cities is low, the core-edge features of economic development are obvious, and the economic status of different cities is different. Finally, the paper puts forward the way to optimize the spatial economic structure of the Jiang-Huai urban agglomeration. On the basis of analyzing the characteristics of the spatial economic structure, and aiming at its shortcomings and problems, the paper puts forward the specific optimization countermeasures: constructing the hierarchical scale structure reasonably. We will continue to improve the urban functional structure, optimize the spatial distribution structure, and continue to strengthen the structure of economic ties.
