常见的交通成本模型和特征价格模型对数据要求较高,因此,利用类比分析方法探讨预估新兴轨道交通城市新建项目对周边房地产价格的增值作用。首先分析了房地产价格的影响因素,初选7个类比指标,结合相关性分析及回归分析将人均GDP和人均消费支出作为最终类比指标。以南京市地铁项目为实例,详细介绍了类比分析法的应用步骤,将南京与北京、上海、深圳、成都几个城市进行类比,得到南京市轨道交通对周边房地产价格的增值效益值。结果表明,与其他常用方法相比,类比分析法普遍相对误差为18%以内,且对数据要求较低,操作简单,特别是对于轨道交通建设处于起步阶段的城市,这一方法可发挥最大的优越性。最后,提出类比分析法的缺陷及在应用过程中的注意事项。
Due to the fact that commonly used Travel Cost Model (TCM) and Hedonic Price Mode l (HPM) require more data,this paper investigates the effect of new rail transit lines on the price of adjacent real estate by analogy analysis.After studying the influential factors of real estate price the seven primary indices were selected for the analysis.Two analogy indices,GDP per person and average personal expending,were finally chosen based on correlation and regression analysis.Taking the rail transit construction in Nanjing as an example,the paper elaborates the application of analogy analysis method,and obtains the value-added benefits of rail transit in Nanjing by comparing with cases in Beijing,Shanghai,Shenzhen,and Chengdu City.The results show that compared with the commonly used methods,the analogy analysis method is easily applicable for cities in the initial stage of rail transit development,requires less data and can limit the error within 18%.Lastly,the author points out the application requirements and the potential weakness of the method.
