TEMPORAL AND SPATIAL ANALYSIS OF REGIONAL DIFFERENCES OF URBANIZATION QUALITY IN JIANGSU PROVINCE

According to the meaning of urbanization and the aim of promoting urbanization,from population urbanization,economic urbanization,residential living urbanization,landscape environment urbanization and infrastructure urbanization,we build the evaluative indices system of regional urbanization quality and use entropy method to estimate the urbanization quality of the counties and cities of Jiangsu Province from 2001 to 2009.And then taking these as variables,we also use coefficient of variation to analyze the process and pattern of urbanization quality of the counties and cities of Jiangsu Province.The results are as follows: firstly,since the beginning of the new century,the differences of regional urbanization quality in Jiangsu Province have shown the trend of expansion;secondly,the urbanization quality of cities and counties in Jiangsu Province improves gradually,but their spatial polarization becomes increasingly obvious at the same time.Prefecture-level city downtown areas give priority to downward convergence,central and northern Jiangsu counties give priority to upward convergence;Lastly we should accelerate counties economic development of the northern and central areas in Jiangsu Province(especially in coastal areas),constantly improve their infrastructure construction and people's living standards,establish the regional cooperation organization which is promoted by the government in order to break through the region as a unified regional economic system.With those measures have been finished can we accelerate the upgrading of the urbanization quality development in Jiangsu Province,narrow the disparities in regional development and promote the strategic transformation of urban development initiatives.
