THE SPATIAL VARIATION AND AFFECTING FACTORS OF THE HOUSING PRICE GRADIENTS——THE CASE OF BEIJING
基于单中心假设，使用特征价格模型估计北京住房价格梯度，发现加入空间方向虚拟变量后模型解释力显著提升，价格梯度在不同方向区域存在明显空间变化，主要受城市空间结构和交通基础设施影响。
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.
