武汉市轨道二号线沿线房地产增值效益分析

针对城市轨道交通投资的外溢性特点,对武汉市轨道二号线沿线房地产增值效益进行量化估算。首先预测轨道交通开发利益的影响范围,接着建立住宅房地产增值预测模型,并在此基础上对该模型进行改进,建立商业房地产增值预测模型,计算武汉市轨道二号线沿线住宅和商业房地产在地铁建设影响下的增值空间。分析结果表明：距离市中心或副中心较近的车站对周边楼盘价格影响的地理范围较小,而距离市中心较远的车站对周边房地产的影响地理范围较大;其次,无论是住宅房地产还是商业房地产价格,距离市中心或副中心越远,受地铁建设影响越明显,并且商业房地产的增值幅度比住宅房地产更大。

Calculation of External Effect for Wuhan Rail Transit Line 2

Considering the urban rail transit has the feature of externality,this paper calculate the external effect of Wuhan Rail Transit Line 2. Firstly the sphere of influence of rail transit is predicted. Then based on an assessable model in advance,the paper assesses the price increase of the houses around the stations. On the other hand,based on existing real estate increment model,the model which is adequate for the calculation of commercial real estate value-added is modified. Taking the Rail Transit Line 2 as an example,the value-added space of commercial real estate induced by subway construction is calculated. The results are as follows： Firstly,the stations close to city center affect the surrounding estate prices in a smaller geographical area,while the stations far away from city center affect it in a larger geographic scope. Secondly,rail transit has an important impact on raising the prices of the both residential and commercial real estate around the stations. Furthermore,in the suburban area,rail transit has even greater impact on the prices than in the central part of Wuhan. And by comparison,the added value in commercial real estate is much more than residential real estate.
