Spatial Heterogeneity and Locational Determinants of Bid-rent of Office Land in Beijing
基于竞租理论和空间计量模型，利用1992-2012年北京中心城区办公用地交易数据，分析了办公用地竞租的空间依赖性和异质性，发现集聚经济是影响办公租金空间差异的最重要因素，并揭示了多中心发展趋势。
Based on the bid-rent theory and spatial econometric models,this paper examined spatial dependency and spatial heterogeneity of bid-rent of office land in Beijing.By collecting the transaction dataset of office land from 1992 to 2012 in the downtown Beijing,we reported the kernel density estimation maps of the transacted office land.The maps show that office lands in Beijing,in general,have evident agglomeration characteristics.In general,the bid rent of office land in Beijing decreases gradually from city center to periphery.However,it also presents an evident spatial variation.The bid rent reaches the peak at CBD,financial street,Zhongguancun and Olympic Park area,etc.In the same period,the emergence of several hotspots of office space reflects the polycentric development trend of spatial structure in Beijing.By employing mono-centric and poly-centric regression models,and geographical weighted regression model,we evaluated the main determinants that have significantly affected the spatial pattern of office land rent in Beijing.It concluded that agglomeration economy is the most important factor for the explanation of urban spatial variation of office rent.There is significant spatial dependence and spatial cumulative effect in the distribution of office location,that is,the existing office clusters will affect the location of new office space.As China’s urban land market develops mature and the impact of the market mechanism on land development mode is strengthened,it’s important to study the relationship between land price and spatial location.It can help to enrich and improve the spatial structure theory of urban land use,and provide references for land use and planning practice as well.
