空间尺度对城市竞标地租理论的适用性影响分析——以深圳经济特区为例

The Applicability of Spatial Scale on the Bid Rent Theory:a case Study of Shenzhen

以深圳建筑普查数据为基础,以GIS空间分析为技术方法,整理得到深圳经济特区城市尺度和组团尺度的建筑平均高度和商业办公、工业仓储和居住等三大类土地利用数据,对比分析空间尺度对城市竞标地租理论的适用性影响。结果表明:组团尺度的土地竞租能力和土地利用强度是符合距离衰减效应的,而城市尺度的地域空间结构相比组团尺度则显得更复杂,体现了空间尺度对竞标地租理论的适用性。

The bid rent theory tells that the urban land use follows the principle ＂of best value use of the land while the bid rent ability and land use intensity present a distance decay effect from the city center to the outside. The theory premises of classic urban regional spatial structure such as the Cosmetic Zone Theory,while as the development of social economy and increment of city construction area,the modem urban regional spatial structure becomes so complex that it is hard to directly make the theory applicable to the research on the complex regional spatial structure of a city. Considering the spatial scale effect,the single cluster within a city matches the theory well,so the spatial scale has applicability on the bid rent theory. This paper is based on the construction census data of Shenzhen Economic Zone, and uses GIS spatial analysis method,and concludes the average architect height and land use results of city scale and cluster scale and then compares the applicable effects of the spatial scale on the theory. Results show that the land bid rent capacity and land use intensity of the cluster scale matches distance decay effect better, and the regional spatial structure on city scale is more complex than the cluster scale, showing that the spatial scale has great applicability on the bid rent theory.
