北京商品房价格的空间分布及变化趋势(2002-2014)

Spatial Distribution and Its Change of Housing Price in Beijing(2002-2014)

北京市新建商品住房的平均价格在近12年增长了约3.6倍,但平均值不能反映价格的空间特征。利用平均房价等值线,分析2002年至2014年上半年住房价格的空间分布变化,并从交通基础设施的角度进行解释。研究发现,这一时期新建住房区位向郊区迅速扩展,郊区与南部地区的相对房价出现了增长,使不同地区的价格差距得以缩小,但近年来郊区价格的增长趋势有所减缓。从交通基础设施来看,北京城市道路和轨道交通建设显著降低了不同地区的区位条件差异,引导住房建设向郊区与南部地区转移;但交通改善本身不足以对城市空间结构转变起决定性作用,郊区就业与服务的发展速度落后于交通设施,不利于形成健康的住房市场。

Average housing price in Beijing has increased by approximately 460% during the last 12 years.Average itself,however,obscures the location attributes of price.Based on average price contours,the research analyses the spatial distribution of housing price from 2002 to the first half of 2014 and explains it using transportation infrastructure.The research finds that the newly-built residential projects during this periodhave swiftly spread to the suburb and relative prices of suburban and southern projects have gone up,which narrows the gap between different locations within the metropolitan area;nevertheless,this increase in suburban price has slowed down.From the perspective of transportation infrastructure,improved highway and rail transit have reduced the difference between different locations and led residential development to the suburb and southern city.However,the transportation development alone is not enough to determine the change of urban spatial structure;the lagged development of suburban employment and public service retards the forming of a healthy housing market.
