摘要
A novel hedonic model based on spatial accessibility is proposed.This model changes the traditional planar hedonic model from two dimensional to three dimensional(3 D).A 3 D model through space syntax and quantum geographic information system platform was developed.Then,this model was tested through an analysis of 174 residential areas in Tianjin’s central district.Accordingly,the impact of 3 D location characteristics on the property value was examined.The results suggest a positive correlation between spatial accessibility and property value on a city-wide scale.Mass transit may exert negative influences,such as traffic noise and air pollution.On submarket scales,the property value may be influenced by urban functions,historical background,and street layout.The negative correlation between the bedroom number and price reflects a higher real estate market investment value in the Heping District and the high demand for small and medium-sized houses in the Hongqiao and Hedong Districts.This study provides insights for improving neighborhood plans and housing design,and policy making concerned with promoting balanced progress of social,economic,and spatial priorities.
为明确空间可达性、房产特征与房产之间的关系,提出了基于空间可达性的新特征模型,使传统的平面特征模型从二维尺度转向三维尺度.通过空间句法与QGIS平台构建了三维特征模型,对天津市市中心174个居住区的分析结果验证了三维空面特征对房产价格的影响关系.结果表明,市级尺度的空间可达性与房价呈正相关,但公共交通带来的噪音与空间污染可能会产生负外部性.在行政区划尺度,房产价格受到城市功能、历史背景与街道布局的影响较为显著,如卧室数量与房价之间呈现的负相关关系分别体现出和平区房产市场的高投资价值与红桥区、河东区对中小型住宅的高需求.研究结果可为改善住宅设计、社区规划以及城市发展战略提供决策依据,促进社会、经济与空间的平衡发展.
