Research On Economic Spatial Linkage Of Jinan Metropolitan Area On The Basis Of Urban Flow

Under the impetus of the economic globalization and information, Metropolitan area plays an increasingly important role in regional economic competition and cooperation. Metropolitan area is an open system, its formation force is on a "flow" in the form of inter-city interaction. That is space-space flow about elements of various in inter-industry and inter-city of the metropolitan area, the flow includes information flow, logistics, capital flow, technology flow and service flow, etc. The result is forming spatial linkage of the metropolitan area's economy. Jinan Metropolitan area is as a part of strategies of Shandong metropolitan regional development. It is an important part of Northeast Asia and Bohai-Rim Economic Circle, north-south to undertake two major metropolitan of Shanghai and Beijing, connects Shandong Peninsula Urban Agglomeration. Jinan Metropolitan area has great significance for the promotion of economic and social development in Shandong Province, the construction of "big and strong, rich and beautiful" new Shandong.At present, the geographic study on the theoretical system, formation mechanism, momentum and spatial structure has been very in-depth. However, the study on the economic spatial linkage is insufficient. In addition, Jinan metropolitan area has just been formed, the research mainly confined to the building of metropolitan area, development strategy, urban system, etc. Therefore,urban flow is as a starting point in this article. Theories and methods of urban geography, economic geography, quantitative geography and regional economics are used. With mathematical statistics and analysis software, economic spatial linkage of Jinan metropolitan area is analyzed qualitatively and quantitatively. Specific contents include: exploring the theoretical system of economic spatial linkage of the metropolitan area;Based on urban flow model,the paper analyses characteristics of from intensity and structure of urban flow; The paper also studies spatial structure of the Metropolitan economy, including the size class structure, functional structure and spheres structure; The basis of the above aspects, optimal strategies of economic spatial linkage based on urban flow Are systematically presented. In this paper, methods and conclusions include:By calculating the extrovert energy, orientation and intensity of urban flow of the cities, the intensity of urban flow is obtained, economic spatial linkage is analyzed quantitatively, and is compared horizontally. The result is: Jinan is the core of linkage, linkage is not tight enough; By building the model of the intensity and using the analysis of linear regression, it is discovered that the third industry hold leading position in the intensity of urban flow.From the intensity of urban flow, urban population, urban first degree and rank - size rule, This paper explains the scale structure of Jinan metropolitan area, the first city status of Jinan is not obvious, medium and small cities are too much. According to location providers and functional intensity of main outward sector in Jinan metropolitan cities, the functional structure of cities is obtained combination of the status of the cities industries; Based on the formula of strength of economic linkage and breaking point, spheres structure is divided.Based on model of Intensifying Urban Flow, in the paper economic spatial linkage is enhanced, from the linkages of circle and outsider urban, the circle city's linkage.
