上海地铁8号线对城市住宅价格的时空效应定量研究

以上海地铁8号线周边二手房交易数据为样本，运用基于栅格建模的可达性分析原理计算时间成本以划定8号线影响范围，进而筛选影响住宅价格的特征变量，并应用特征价格模型分析8号线对周边住宅价格影响的时空效应.结果表明，8号线对其周边住宅价格产生正效应，距离地铁站点越近，住宅价格越高，且随着远离地铁站点，这种影响逐渐减弱.另外，8号线的开通对周边住宅价格产生明显的时间效应，导致其价格上涨，且在不同区位具有不同上涨幅度.关于划定轨道交通影响的空间范围，较之以前的凭经验判别在技术方法上进行了新的尝试，对轨道交通新线路开通影响周边房地产价格的时间性进行了探索.

Quantitative Research on the Spatial and Temporal Effects of Shanghai Metro Line 8 on Urban Housing Price

By collecting the record of second hand housing price around Shanghai Metro Line 8, this paper applies a grid based accessibility analysis model to compute the impacted areas. In addition, the characteristic variables are defined in oder to analyze the spatial and temporal effects of the Line 8 on housing price around it by applying the hedonic price model. The result shows that the Line 8 has positive effect on housing price. If the location of the house is close to the Metro station, the price will be higher than other houses; and the impact gradually gets weaker when housing is farther and farther away from the Metro station. Furthermore, Shanghai Metro Line 8 has an obvious temporal effect, Metro station in different location has different rising rate. The accessibility analysis and temporal effects of new line involved in this paper are seldom used.
