摘　　要：摒弃以家庭收入和住房价格平均数(或中位数)为核心的传统度量逻辑,本文以家庭收入分布和住房价格分布为基础,借鉴洛伦兹曲线和基尼系数思想,运用住房可负担倍数、住房可负担百分比和住房可负担度等微观指标以及住房洛伦兹曲线和住房基尼系数等宏观工具,构建了一个全新的从家庭到社会的住房负担能力度量理论框架。运用该理论对上海、深圳、武汉和苏州四个一二线城市二手住房负担能力的实证研究表明:四城市中等收入及以下家庭住房负担能力普遍偏低;除苏州外,其他三城市中等收入和中高收入家庭的住房负担能力也不乐观;四城市的社会住房负担能力不佳,其中上海和武汉的情况尤甚;房价较低的二线城市的住房负担能力状况不一定优于房价较高的一线城市。Following the ideas of Lorenz curve and Gini coefficient, and taking account of the overall distribution of household income and house prices rather than just the mean or the median, this paper built a new theoretical measurement system for housing affordability. It was deduced through a path from households to society by using individual indicators such as housing affordable multiplier, housing affordable percentage and housing affordable degree, and aggregate analyzing instruments such as housing Lorenz curve and housing Gini coefficient. The empirical analysis for the second - hand housing market in four cities in China showed that the housing affordability of households with disposable income below medium -level was low in all sample cities; except Suzhou, the housing affordability of households with medium and medium higher income is not satisfactory; and the social housing affordability in those cities wasn＇ t good enough, especially in Shanghai and Wuhan. No evidence showed that the situation of housing affordability in a big city is certain to be worse than that in a smaller city.
