城市轨道交通可达性提高和住宅价格增值关系

从分析影响因素出发,将城市轨道交通对住宅价格的影响分解为交通效益和集聚效益,并建立可达性提高计算模型进行量化.以上海市轨道交通11号线的16个车站为例对可达性提高计算值和住宅价格增值之间的关系进行分析.实例研究结果初步表明,城市轨道交通对住宅价格的影响约为城市轨道交通对住宅年可达性提高的5倍,并且在城市轨道交通开通前后就已经释放;各个车站因自身的区位及在城市轨道交通网络中的位置不同,对其影响范围内房价的影响程度不同,影响幅度分布在2%~18%之间,并呈现郊区大、市中心小的趋势.该方法可以为规划阶段的城市轨道交通线路开发利益还原及车站周边土地开发建设提供参考.

Analysis of Relationships between Urban Rail Transit Accessibility Improvement and Residential Property Appreciations

The impacts of urban rail transit on residential property values were classified into traffic effects and agglomeration effects, both of which could be measured by the accessibility improvement model. A case on 16 stations of Shanghai Metro Line 11 was studied to verify the model by analyzing the relationships between the accessibility improvement values and the residential property appreciations. The results indicate that the residential property appreciation is about 5 times the accessibility improvement value per year and this has occurred as soon as the stations open due to the expectation effect. Furthermore, because of the different locations of the stations, the impacts are markedly different, ranging from about 2 percent in the city center to about 18 percent in suburban areas. This method can provide suggestions for urban rail transit value capture and land use planning of areas surrounding the stations.
