城市轨道交通对住房价格影响的计量分析——以南京市地铁1、2号线为例

本文从理论和实证角度,分析验证了城市轨道交通对沿线站点住房价格的影响。首先通过理论分析提出假说,然后基于特征价格方法构建计量分析模型,利用南京市地铁1、2号线站点附近2km范围内二手楼盘数据,实证分析了城市轨道交通地铁对沿线站点住房价格的影响。结果表明:1城市轨道交通对沿线站点住房价格产生了显著的增值效应,不同距离范围影响程度不同,距地铁站点500m以内住房价格比500m以外高出14.3%,1 000m以内住房价格比1 000m以外高出8.9%,1 500m以内住房价格比1 500m以外高出3.9%,当距离范围超过1 500m后,增值效应在统计上不显著;2轨道交通对住房价格的影响程度与距地铁站点直线距离存在着显著的倒"U"形关系,影响程度随距离先增大后减小,在距地铁站点大约320m时影响程度最大;3轨道交通对沿线站点住房价格的影响程度具有显著的分市场效应,对郊区市场的影响程度要远大于主城区市场。

Econometric analysis of the impacts of rail transit on property values:the number 1 and 2 lines in Nanjing

Urban rail transit results in an improvement of residents' accessibility and a change in urban traditional locations. Urban rail has a significant effect on property values,and it is necessary to analyse the extent and degree of impact. Here,from the perspective of theoretical and empirical analysis,we verify the impacts of urban rail transit on property values in Nanjing,Jiangsu. Using theoretical analysis and empirical data we propose a hypothesis and then build an econometric analysis model and hedonic price method based on an area within 2km of subway lines 1 and 2 in Nanjing. We found that urban rail transit has a significant multiplier effect on property values,the influence of different distances from the subway station is different:property values within 500m of a subway station are 14.3% higher than those beyond that distance;property values within 1 000 m of a subway station are 8.9% higher than those beyond that distance;and property values within 1 500m of a subway station are 3.9% higher than those beyond that distance. When the distance is greater than 1 500m,the multiplier effect is not statistically significant. There is an inverted U relationship between the impact of rail transit on property values and linear distance from a subway station:as distance increases,the influence degree firstly increases and then decreases and the greatest degree of influence is 320m from the subway station. The impact of rail transit on property values has a sub-market effect and the influence on rural markets is far greater than on urban markets.
