中文摘要：

本文以江苏省68个地级与县级市的城市地价为样本，运用因子分析方法对影响地价的诸多变量进行分析，发现城市集聚规模与城市经济发展水平是影响地价的重要因素。对江苏省城市地价进行地统计分析，发现江苏省城市地价明显表现出区域空间分布规律，表现为江苏省城市地价存在南北、东西两个方向上的梯度变化，运用线性回归方法求得两个方向上的梯度值；江苏省城市地价整体有一定正相关性，但局域自相关性表现不强；地价以南京、苏州为高地价点，省内地价存在沿沪宁铁路与长江的高地价条带区域。结合因子分析结果对以上规律做出解释。

英文摘要：

Taking the land price of 68 cities in Jiangsu province as sample data, the reason of influencing the city land price is analyzed Firstly. Ten variables relevant to city land price are introduced. By factor analysis, we got two new factors, one is the factor who is about the city volume, and the other is about the economic developing level. Further more, through making multiple regressions simulating analysis, we found the two factors can explain the city land price easily, and their influence weight is almost same. Second, by interpolat- ing the land prices of 68 cities in, we found the city land price in Jiangsu province has obvious regular pattern. The south part of Jiangsu has dark color, which represents higher price; the middle part of the province has rather light color, which represents moderate price; in the north, the color is the lightest, which means the land price is the lowest, there is the darkest color in the dark color part, it is the highest price part. But the ten- dency along the west-east direction is not obvious in the interpolating graph. The descending gradient values in two directions were got through regression analysis. The comparing result represents that the descending gradient value along north-west direction is larger. The other phenomenon is the land price in Jiangsu province has two highest parts, which are called two poles. They are Nanjing city and Suzhou city. By profile and regression analysis, found they have different influence range. Due to depending on huge economic body-Shanghai city, the Suzhou city has larger influence range. Another characteristic about city land price in Jiangsu province is that a higher city land price strip was produced along the Yangzze River and Hu-ning Railway due to transportation reason.
