在总结已有城市住宅价格空间分异相关理论体系的基础上,提出了住宅优势度的概念和理论,认为在城市内部,某住宅相对于其他住宅所具有的优势及其量化程度称为住宅优势度,是住宅相对优势的度量。住宅优势度决定住宅价格,住宅价格是住宅优势度的货币体现。构建了住宅优势度研究的基本框架,阐述了其假设前提,提出了其基本构成要素和综合评价体系。将该视角应用于扬州市的案例研究,结果表明其住宅优势度与住宅价格存在显著的正相关关系。证明本文构建的住宅优势度理论及其评价体系具有合理性和可行性,为城市住宅价格的构成要素与影响机理分析提供一个可供选择的新视角。

The differentiation of urban housing price is an important issue for urban geography and urban economics. The theory of housing dominance is that, the dominance and its quantification of certain urban residence against other houses is called housing dominance, which is a measurement of housing relative dominance. The housing dominance determines the housing price, while housing price is a monetary embodiment of housing dominance. It has set up the basic frame of research on housing dominance, explained its prerequisite of assumption and proposed its basic elements and evaluation method. Thereinto, the basic frame of housing dominance includes building dominance and external dominance. The assumptions are housing market of monopolistic competition, lack of inelastic of short-term supply, rational-economic man, housing market of free trade. The basic elements of housing dominance are composed by the own housing dominance and dominance of external action, including 4 aspects of single housing grade and level, community construction grade and level, location and convenience, and surrounding landscape and environment, and then revised by expected elements. On this basis, the appraisal system of housing dominance is established. The appraisal subsystems are composed of housing type and age, architectural feature, community environment, community level, location, life convenience, surrounding landscape, and surrounding environment. Then computing method of weighted summation is applied to catch the score of housing dominance. When such theory and method are applied to the case research of Yangzhou City, the result indicates that, there is obvious positive correlativity between housing dominance and housing price, which has proven that the theory of housing dominance and its evaluation system set forth herein are reasonable and feasible.
