北京市居住用地出让的时空格局演变

:Since t he 1980s Chinese cities have experienced dramatic transformation of its land use system from free allocation toward a leasehold system. Recent literature has drawn attention to spatial features of land market in transitional Chinese cities, in comparison to its counterparts in advanced market economies. Nonetheless, research on this issue haven been limited by the lack of systematic data - especially spatial data - on land leasing parcels as well as other related data sources. Based on about 2600 residential land leasing parcel data from 1992 to 2006 and Beijing Digital City integrated data , this paper is processing general evaluation and actual description of the tempo spatial characteristics of the residential lands’ expansion since China launched the market-oriented land-leasing policy in 1992. The authors choose the spatial analysis met hods with the aid of GIS, to evaluate the spatial pattern in t he downtown area of Beijing. Generally speaking, the residential land market has a “Classic Concentric” overall pattern and an obvious spatial differentiation structure over time. In particular , we studied some major residential districts of Beijing including CBD , Zhongguancun , and Olympic-Park district etc. Based on the analysis, we found t hat : (1) The residential land-leasing market of Beijing showed a growing trend from 1992 to 2006 , with the expansion of t he residential lands’ number , size , and t he flat tendency of residential land price; (2) Residential land price showed a “North high-South low” spatial pattern, and residential land number and size showed an “East high-West low”spatial distribution structure; (3) The high residential land price sections extended from city center to t he outside from 1992 to 2006 gradually ; (4) The Tianqiao and CBD districts have become the highest residential land price sections of t he North-South axis and t he East-West axis, respectively. And the residential land price is relatively high in some districts with better locations. We believe our research would enrich the existing knowledge of the emerging urban land market in transitional China , and provide information for further land and housing policy making.
