选取超大型综合性城市以外的全国不同区域和职能类型的33个城市为样本,采用地价密度梯度曲线模型,对其进行曲线回归分析,得出各城市商业、住宅地价的中心值和曲率系数。分析发现现阶段我国城市地价密度梯度曲线总体上符合城市地价变动的一般规律:城市中心地价与城市规模呈正相关关系;曲率系数与城市规模呈负相关关系;商业地价曲线曲率系数比住宅地价曲线曲率系数高。再此基础上对地价梯度曲线曲率系数进行聚类分析,总结出中国城市地价的不同类型特征。另外通过对我国东中西部30个城市样本的地价梯度系数的统计分析,从空间差异角度发现三类地区的地价呈现不同特征规律。 |

Taking 33 cities from different regions and categories in China as research objects,this essay carries out land price curve regression analysis to simulate their land price density gradient.Then some coefficients of density gradient curve of urban commercial and residential land price are obtained.According to these coefficients,the phenomenon of Chinese urban land price density curves adapting to the normal rules of market economic countries is observed through analysis,which indicates that the city land price can reflect the true value of land,the main method of allocation of land resource in China through 30 years of marketing reform.Moreover,the conclusion that land price density gradients have different categories in China has been drawn based on clustering analysis of commercial and residential curve curvature.According to the commercial land price curve curvature and residential land price curvature,the cities in China except multi-center cities such as Beijing and Shanghai,are identified into four types.Every type of city is corresponding separately to different levels of development,city capacity,economic scale and parameters of land price curvature.So through analyzing land price curvature,we can reveal different city land pricing characteristics and its phase of development.By comparing land price density gradient parameters of the three regions in China,namely eastern China,central China and western China,this paper presents the spatial distribution of city land prices in different regions.The developed and densely populated eastern China has the maximum average of city center land price,minimum average of curve curvature,and biggest standard deviation of city center land price.With the moderately prosperous economy and medium-density population,central China has the minimum average of curvature,but the minimum average of city center land price and smallest center land price standard deviation.As for western China,its average city center land price and center land price standard deviation are at an average level,its averages of curvature and curvature standard deviation are maximum,although it has the most sparsely population. |
