摘要
住宅价格影响因素的研究对于购房者购买住房及政府制定相关政策具有重要影响。然而,目前对于住宅价格问题的研究大多从宏观角度进行,而从微观角度入手的相对较少。此外,对住宅价格的研究通常需要建立多元回归方程,但这样会造成多重共线性问题,导致伪回归,不能准确地分析各因素对住宅价格的影响。针对该问题,本文从微观角度出发,运用定量与定性相结合的方法,建立特征价格模型,并且选择逐步回归法对其进行修正,将其中显著性不强、经济意义不明显的变量逐步剔除,从而更准确地探究影响住宅价格的主要因素。本文以南京市住宅价格为实验数据,并初步选择12个影响因素对该方法进行验证。结果表明,该方法能够有效地剔除二级商业中心、建筑类型、生活配套设施3个显著性不强的影响因素,保留重点学校等9个影响较大的因素。本文方法更为精准地分析了住宅价格的影响因素,为购房者购买住房及政府制定相关政策提供了一定的理论基础。
With the urbanization and the rapid growth of economy, the housing price of cities continues to rise and the spatial differentiation of housing price increases, which has attracted a widespread attention from the public and the government. Exploring the influencing factors of housing price is of great significance for understanding house-buying of the public and provides useful support for the government to formulate relevant policies. Until now, many researches have studied the influencing factors of housing price from a macro perspective and only a few studies are conducted from the micro perspective, which leads to inadequate understanding of the influencing factors of housing price. In addition, the method of establishing multiple regression equations is usually adopted to study the relationship between housing price and multiple influencing factors. However, the selection of influencing factors are usually subjective, which leads to an artificial regression that cannot characterize the influence of various factors accurately. To solve these problems, a hedonic price model combining both quantitative and qualitative methods is proposed from the micro perspective of structure characteristics, location characteristics, and neighborhood characteristics in this study. Moreover, a stepwise regression method is applied to modify this model by eliminating non-significant factors. To validate the proposed method, a case study in Nanjing city, Jiangsu is conducted, and 12 primary influencing factors are selected. The results show that the proposed method eliminates three insignificant influencing factors including secondary commercial centers, building types, and living facilities, and keeps the rest nine factors. Compared with traditional methods, this paper analyzes the influencing factors of housing price more quantitatively and provides a theoretical basis for house-buying of the public and policy making of the government. What’s more, it is conducive to the real estate management department to have an in-depth
