长三角城市群各业用地价格的空间分布格局及影响因素

运用空间自相关及地理加权回归方法,揭示长三角城市群各业用地价格的空间分布及关联特征,并分析其影响因素的空间异质性,丰富和发展城市群地价空间分布规律的理论研究。研究结果表明:工业用地价格普遍偏低,商住地价价格较高,符合城市间土地级差收益规律,但商住倒挂现象明显;在空间分布上,工业地价从浙东南向苏北呈梯度递减,在空间上呈现显著空间正相关,表现为低值空间集聚;居住地价在空间上呈现出较强的空间正相关,具体表现为一、二线城市为高值集聚,商服地价不存在空间自相关性;人均可支配收入、公共财政支出对长三角城市群工业地价的影响空间差异显著,城市等级、国内生产总值和人均可支配收入对居住地价的影响空间差异明显,商服地价主要受到社会消费品总额、每万人公共汽车数量和公共财政支出影响。

SPATIAL ANALYSIS OF VARIOUS LAND PRICE AND ITS INFLUENCING FACTORS IN YANGTZE RIVER DELTA AGGLOMERATION

This paper aims to reveal the spatial distribution and influencing factors of various land price such as industrial,commercial and residential land,etc.in Yangtze River Delta Agglomeration.Both spatial autocorrelation model and geographically weighted regression model were used to enrich and develop the theoretical study on spatial distribution of land price in urban agglomeration.The results showed that industrial land prices were generally lower,commercial and residential land prices were higher.It was in accord with the laws of urban land differential benefit,whereas it appeared the phenomenon of inversion between commercial and residential land price.The industrial land prices descended from the southeast of Zhejiang Province to the north of Jiangsu Province,and it showed a significant spatial agglomeration with low values.There is a strong spatial correlation in the residential land prices differences.The first and second tier cities showed high-value clustering,whereas commercial land prices showed a weak spatial correlation.The impact of disposable personal income and public finance expenditure on the industrial land price showed significant spatial differences,the spatial difference of influencing factors,including urban grade,GDP and disposable personal income on residential land price was obvious,and the commercial land price was mainly affected by total social consumer goods,number of buses per million and public finance expenditure.
