城市房地产价格空间结构研究前沿动态————基于城市经济学的视角

本文从城市经济学的视角出发，梳理了城市房地产价格空间结构的理论演进脉络和实证研究，为国内开展房地产价格空间结构研究提供借鉴。研究指出城市房地产价格空间结构研究通常是通过估算价格梯度（竞租曲线斜率）来衡量的。国外城市经济学者在三类假设（单中心假设，多中心假设，对城市空间结构不事先假设）三大方法（早期的负指数函数模型、特征价格模型和改进的重复销售模型）下展开价格梯度估算研究的。最后对国内的研究进行了评论和展望。

A Survey of Studies on Property Price Spatial Diversity

This paper reviews the studies that have been conducted on property price spatial diversity. Prices gradient is an important index used to measure price spatial differentiation. There are basically three different methodologies of estimation and three different assumptions on the spatial structure of an urban area. The three methods are: 1） the negative exponential model; 2） the hedonic pricing model and 3） the repeat-sales model. And the three assumptions are: 1） the monocentric assumption; 2） polycentric assumption and 3） no priori assumption about the urban spatial structure. The methodologies and the findings of these previous studies are compared and analyzed to clarify the path for further studies.
