基于GWR模型的武汉市住宅地价影响因素研究

Influencing Factors of Residential Land Price in Wuhan Based on GWR Model

采用文献综述法、地统计法、GWR模型等方法,在分析武汉市2004—2011年住宅地价空间分异特征的基础上,筛选影响住宅地价表现的因素构建GWR(地理加权回归)模型,探索每一影响因素对住宅地价影响力的区位差异,以期从微观区位的角度为城市规划和房地产开发提供建议。研究表明:总体而言,武汉市住宅地价空间呈现较为明显的单中心结构,并随着到市中心距离的增加呈圈层式递减;主干道、地铁及规划管制(容积率)对武汉市住宅地价表现的影响力较大;规划管制(容积率)、主干道、生活品市场及教育资源对住宅地价的影响力具有明显的空间分异特征,即以上因素对住宅地价的影响力在不同的微观区位具有统计学意义上的明显差异。

Based on literature review method, Kriging interpolation, GWR model and analysis on spatial variation characteristics of 2004-2011 residential land price in Wuhan city,this paper screens fac- tors of residential land price and builds GWR model（geographically weighted regression） to explore the regional differences of residential land price influenced by each factor which will provide advice to urban planning and real estate development from the micro perspectives. The result shows that, first, the space of residential land price in Wuhan demonstrates single-centered structure on the whole, and shows a di- minishing circle style with the increasing distance from the city center; second, the main road, metro and planning control （floor area ratio） have the big influence on residential land price; thirdly, planning con- trol, main roads, supermarkets and educational resources have obvious spatial differentiation characteris- tics to residential land price. All the above factors on residential land price have great influence in differ ent micro-locations and the obvious difference is statistically significant.
