北京房地产中介空间格局演化特征及驱动因素分析

EVOLUTION CHARACTERISTICS AND DRIVING EFFECTS OF SPATIAL PATTERNS OF BEIJING REAL ESTATE AGENTS

本文基于微观企业数据,采用泰森多边形、核密度及空间自相关方法,多尺度考察2001—2010年北京房地产中介门店空间格局演化特征,通过构建地理加权回归模型(GWR),探究2010年房地产中介空间格局驱动因素。研究表明:(1)房地产中介集中分布在城六区,数量增速最快功能区是城市发展新区。(2)空间格局不均衡性增大,空间集聚态势加强。(3)集聚主核心点出现由"东城"向"朝阳"方向的东推位移,集聚程度加深,主核心区团块面积扩大,次级核心点增多,"两轴、两带、多中心"基本版图形成。(4)空间集聚现象明显,热点区域扩张,但始终集中在区域中心。(5)驱动效应最大的因素为常住人口,多种驱动因素效应均比较强的街区(乡镇)基本上属于各区县经济水平相对发达的区域。此外,政府政策对其影响也较大。

To develop the real estate intermediary industry can improve labor efficiency, reduce transaction costs, and promote the sustainable development of real estate industry. To study the evolution of the spatial pattern and the optimal layout of the real estate intermediary industry is of great theoretical and practical significance to promote the sustainable development of the real estate industry. Based on the data of micro enterprises, using the Tyson polygon, kemel density and spatial autocorrelation method, this paper study the spatial pattern evolution characteristics of Beijing real estate intermediary stores from 2001 to 2010 through multi scale, then, we use construction of geographically weighted regression model （GWR） to probe into the driving factors of the spatial pattem of real estate intermediary in 2010. The research shows that： 1） The real estate agency is concentrated in six district of central city of Beijing.The functional area with the fastest growth rate is the new urban development area. 2） The imbalance of spatial pattern increases and the spatial agglomeration trend is strengthened. 3） The main core points of the cluster are moved eastward from the ＂Dongcheng＂ to the ＂Chaoyang＂ direction.The degree of agglomeration is deepened and the area of the main core area is enlarged.Secondary core points increase. The basic layout of two axle, two and multi center is formed. 4） The phenomenon of spatial agglomeration is obvious, and the hot spot is expanding, but it always concentrates in the regional center. 5）The biggest driving factor is the resident population. Basically, a block （town and town） with the effects of a variety of driving factors are obvious that is the region with relatively developed economic level in each district and county. In addition, the government policy has a great impact on it.
