The Development Model Of Primary And Sub-Urban Agglomeration In Regional Economic Development

Primary and sub-urban agglomeration is a product of urban development to a certainstage. It is one of the important models for the coordination of the regionaleconomy. Building a regional urban agglomeration has become the trend of world economicdevelopment according World Urbanization analysis for the development process. In the"12th Five-Year Plan" of China made clear instructions on the regional economic integrationand township economic development. The development of primary and secondary centralcities in breaking down the administrative barriers, the rational allocation of resources, andoptimization of industrial structure can not be ignored. The main mode of China’s economicdevelopment is still the satellite city mode, but the analysis of the Yangtze River Delta andPearl River Delta urban agglomeration can be seen, the development of the central city hasbecome a trend. Baoding, Hebei Province made the "one main and three strategic"developments in2008to develop the response to the "12th Five-Year Plan" called, in theurban area as the basis, three times the central city building Dingzhou, Zhuozhou and BaigouHot Springs. This article is against this background, systematic and comprehensive analysisof primary and secondary urban agglomeration model, a clear impact on regional economicdevelopment.Urban development theory and regional economic theory to analyze the formationmechanism of primary and secondary urban agglomerations, in Baoding necessity andfeasibility of the development of primary and secondary urban agglomeration on the basis ofanalysis of the build process of urban agglomerations may problems encountered and todevelop countermeasures and suggestions for promoting regional economicdevelopment. The paper first analyzes the regional urban development theories and conceptsto build a theoretical framework for the article. Secondly, to analyze the mode ofdevelopment of the domestic and international cities base through the development andchanges of these three cosmopolitan city of New York, Tokyo and Paris group and China’sPearl River Delta, Yangtze River city group, leads to the city group from the early stages of development of urbanization to The final form of several models, and focus on the satellitetowns and the multi-center mode. Analyzes the formation mechanism of the group of primaryand secondary cities from the inevitability of regional development, the roles andcharacteristics of the primary and secondary urban agglomerations, and Baoding, for example,the use of concentration and first-degree theory, and by the gravity model and exercisepoints model for sub-centers associated degree and feasibility analysis, correctness clearBaoding three strategies. Finally, through empirical analysis process to identify the problemsfaced by the development of primary and secondary urban agglomerations, and put forwardfeasible suggestions: limited expansion of the region, and take advantage of comparativeadvantage, innovation, improve the intrinsic quality of the city, improve the citycarrying functions to achieve sustainable regional economic development.
