Abstract:

Currently, many provinces have proposed to build urban agglomeration, and there is a certain degree of “urban agglomeration hot” in the country. Urban agglomeration is not simply formed through administrative kneading, We should focus on the development quality of urban agglomeration, and the development quality of urban agglomeration needs us to focus on the city quality development within the group and the city group internal coordination problems between cities. By building the indicators of economic quality development, social and life development quality and environmental quality, we used Dynamic Factor Analysis to evaluate the quality of 38 cities in the years of 2004-2011 in the Yangtze River City Group, and analyzed the space spillovers of city quality within the urban agglomeration using spatial autocorrelation. From the evaluation of city quality within urban agglomeration,We found the spatial characteristics of Yangtze River City Group development quality were that four capital cities formed four distinct cores, the urban development within urban agglomeration with a clear imprint of administrative divisions. The cities of secondlevel quality surrounded around the good quality cities, clearly led by the good quality cities. The third and the fourthlevel cities partly located in the interprovincial border regions, partly were adjacent to the core area, but the core area “polarization effect” was clear, thereby formed “black light” effect. By analyzing the city quality dynamics figure, many cities of general quality and poor quality were in the regressive development, the city quality gap was widening in the urban agglomerations, and it caused serious polarization. We should strengthen the construction of medium and small cities to improve city quality, to improve the small and medium cities hosting population transfer of the core cities, to achieve the rational functional division of different levels of cities, so that to maximize the effectiveness of regional resources, to improve the overall efficiency of urban agglomerations. From the city coordination between cities within the urban agglomerations, the cities within Yangtze River City Group had little spatial impact, and the urban development of the provinces did not break administrative barriers. Interregional economic, social and environment cooperation had no substantial progress, currently the quality development of the Yangtze River city group was not high. We need to learn more from the successful urban agglomerations such as the Yangtze River Delta city group, the Pearl River Delta city group and Bohai Bay city group, promote the cities economic ties within the group cities, strengthen industrial division of labor and cooperation, promote market integration, develope the cities within the urban agglomerations from the “competition” to “synergy”, promote integrated construction of the infrastructure and social undertakings and public service facilities to highlight the “city effect”, and we also need to avoid falling into the strange circle of “executiveled” urban agglomerations development and prevent from “urban agglomeration disease
