中文摘要：

集聚-碎化态势研究作为一种新的空间研究视角与方法，旨在分析并表达区域城镇经济、社会与空间的互动演化趋势。在借鉴美国大都市区碎化指数的基础上，根据当前中国都市区发展的特征，发展了均匀度指数等数学方法。对江苏沿江地区21世纪以来都市区域的集聚一碎化态势进行定量计算和多视角分析，认为作为长江三角洲北翼都市带的江苏沿江都市区域经济要素的总体空间发展呈现出较为明显的均匀化趋势，而治理结构则更趋集中或日集权，这一矛盾无疑将直接影响都市区域未来的持续发展。

英文摘要：

In order to research and express the inter-action trend of regional urban economy, society and space, the analysis of agglomeration and fragmentation emphasized the dynamic evolution relationship of the inter-units, especially of the inter-cities in the metropolitan area. Based on the introduction of the American metropolitan fragmentation index （MFI）, this paper improved the uniformity index （UI） according to the characters of the development for the metropolitan areas in China. Taking the metropolitan area along Yangtze River in Jiangsu Province as an example, this paper selected the data of GDP, social total investment of capital asserts, total retail sales of consumer goods, local public finance income, local public finance expense, gross output value of the secondary industry, gross output value of tertiary industry, foreign capital introduction and actual utilization of foreign capital from Jiangsu statistical annual 1999-2005, to calculate the agglomeration and fragmentation since the 21 st century, aiming to figure out the inter-action evolution relationship of the developing trend of economy, space, and governance in Jiangsu＇s metropolitan area through a multi-dimension analysis. This paper summed up the trends of homogenization and general development. Meanwhile, the paper concluded that the development policy making and governance structure constructing should aim at the characters of different regions, and problems in different regions should be treated in respective ways. Finally, the paper argues that the MFI and the improved UI are appropriate when they are used to analyze the dynamic evolution relationship of inter-cities. The MFI is sensitive in analyzing the the evolution of the metropolitan governance structure while the UI is suitable in expressing the evolution of the economic elements.
