中文摘要：

为进一步缩小由于区域发展不平衡形成的苏南、苏中、苏北三个阶梯性经济发展群的差距,加速苏北地区经济的良性增长,分区域对江苏省的经济展开研究具有十分重要的意义。本文基于1999-2007年间江苏省13个地级市的土地经济密度数据,采用GIS分析法和Pearson相关系数法,对城市土地经济密度变异进行空间分析,并利用库兹涅茨曲线作比对。结果表明：（1）不同区域的土地经济密度的差异大小基本上体现了区域经济的发达程度;（2）不同区域土地经济密度的差异性与区域经济结构的稳定性之间具较大的一致性;（3）发达地区市场化程度对土地经济密度的影响力大;而相对落后区域经济发展助推力更依赖于城市化的强势;（4）发达地区人口聚集更有利于经济的发展,相对落后区则相反。针对以上结论,本文提出3点促进欠发达地区经济发展的建议。

英文摘要：

Because of regional development not balanced formed middle, south and north of three ladder-like economic development groups in Jiangsu. To further narrow the gap between the groups and accelerate economic growth in the northern regions benignly, it has great significance to points out the economic area of jiangsu province to make research. Based on the relevant data from 13 prefecture-level cities from 1999 to 2007 in Jiangsu, in the thesis, GIS analysis and Pearson＇s correlation coefficient were used to analysis the spatial variance of urban land economic density, while Kuznets Curve was applied in the study of the temporal variability of land use. The result shows that land economic density differences of different area basically reflects the regional economic development level. Different regional land economic density differencese has great consistency with economic structure stability. The level of marketization of developed areas has great influence on land economic density, but relatively backward regional economic development aid thrust depend more on the mighty of urbanization. The gathered population of developed areas is more advantageous to development of economy, the relatively backward area is opposite. From the conclusions above this paper puts forward three points to promote the economic development of the underdeveloped areas.
