摘要
基于单中心城市假设,利用特征价格模型对北京市住房价格空间梯度进行了实证研究,发现传统单中心假设由于与实际偏离较大,模型解释能力不强。纳入方向区域变量后的修正模型解释能力显著提高,住房价格梯度在各空间区域表现出显著差异,这种空间互异性主要受交通基础设施与城市空间结构的影响,与北京市的实际情况非常吻合。
Based on the monocentric assumption of the urban spatial structure, the paper uses a hedonic regression model to estimate the housing price gradients of Beijing. The result shows that the model with dummy variables representing the spatial direction attribute explains much better than the original simple monocentric model. The spatial variation of the housing price gradients across different direction region of the city is significantly observed, which is mainly influenced by the urban spatial structure and the transportation infrastructure. The regression result is highly consistent with the actual situation of Beijing.
