房地产龙头企业住宅投资空间分布格局及阶段性特征——以TOP30房地产企业为例

Spatial pattern and stage features of residential investment of real estate leading enterprises:top 30 real estate enterprises as an example

利用空间自相关、核密度估计、平均中心—标准差椭圆等方法,对2009-2017年房地产龙头企业住宅投资分布的空间格局及演化特征进行了探讨。结果显示:房地产龙头企业住宅投资分布呈现正的空间相关关系,且具有空间分异与集聚特征;高高集聚城市分布在京津冀、长三角、珠三角城市群,低高集聚城市毗邻京津、苏州、深圳等高销售城市,高低销售城市为内陆省会城市;住宅投资平均中心迁移轨迹为“驻马店—阜阳—信阳”,总体向东移动30.23 km、向南移动65.39 km;房地产龙头企业住宅投资在地理上趋于集中,但城市间差异程度加大。建议加强都市圈、城市群的一体化建设,增强热点城市对周围城市的辐射及带动作用。

Based on the methods of spatial autocorrelation,kernel density estimation,and the mean center of standard deviation ellipse,this paper studies the spatial pattern and evolution features of leading residential real estate investment enterprises from 2009 to 2017.Results show that the distribution of leading residential real estate investment enterprises shows positive spatial correlation;evidence of spatial differentiation and agglomeration are also significant.High-high clustering cities are mainly distributed in urban agglomerations of the Beijing-Tianjin-Hebei regions,Yangtze River Delta,and Pearl River Delta.The low-high clustering cities are adjacent to cities having the highest concentration of sales such as Beijing,Tianjin,Suzhou,and Shenzhen.The high-low clustering cities are mainly inland capital cities at a provincial level.The center of residential investment moved from Zhumadian to Fuyang and then to Xinyang city with an overall movement of 30.23 km eastward and 65.39 km southward.Leading residential real estate investment enterprises tend to concentrate geographically,but the differentiation of residential investment among cities enlarges.It is suggested to promote the integration of metropolitan areas and urban agglomerations to enhance the radiation effects of hot-spotted cities on surrounding cities.
