基于主成分分析的住宅项目特征定价模型

Housing Project Hedonic Price Model Based on Principal Components Analysis

讨论了房地产特征价格模型在确定新建住宅项目单位销售均价中的应用,针对应用中出现的样本少、部分特征因素间存在相关性的问题,将主成分分析运用于房地产特征价格模型,建立了基于特征因素主成分分析的住宅项目特征定价模型.通过案例,分析了特征隐含价格的经济意义与作用,利用所建模型较准确地确定新建住宅项目的单位销售均价.

Real estate hedonic price model is applied to determine the average sale unit price of newly built housing projeer. In order to solve the problems of the lack of sample and the high correlation of some of the housing characteristic factors with each other in this application, a housing project hedonic pricing model based on principal components analysis of housing characteristic factors has been established. Through a case, the author has analyzed the economical significance of the implicit prices. With the model, the average sale unit price of a newly built housing project can be determined by rule and line.
