中文摘要	本文借鉴工程学和统计学领域构造双变量联合分布函数的方法,首先利用家庭收入和人均住房面积的分组数据分别对中国城镇家庭收入和人均住房面积的分布函数进行估计,然后利用Pearson相关系数法构造了家庭收入和人均住房面积的二维联合分布函数,并依此讨论了我国保障性住房体系中准入标准和保障范围之间的关系,对比分析了保障性住房供需端的匹配情况.整体来看,地方现行的保障房申请条件能够覆盖12%~32%的城市家庭,且各城市间存在较大差异;将这一保障范围与国家"十二五"期间3600万套保障房建设任务的分配进行对照,可以计算出7大地区中代表性城市的保障性住房的供需比在0.6~1.9之间变动,存在较为显著的供需不匹配现象.本文在最后还提出了"保障范围无差异曲线"的分析工具.本文的测算方法和分析工具可以为相关政策进一步细化提供决策支持.; This paper estimates the distribution functions of household income and living space per capita in Chinese cities,based on the statistic data of these two variables which are presented in groups.Then we combine the two distribution functions into a joint distribution function of "income-living space" for urban households using the Pearson correlation coefficient method.Based on this estimated joint distribution function,we present the relationship between the share of households that should be covered by public housing policy( "household coverage ratio") and the eligibility requirement in 20 cities,and also compare the size of this share(demand-side) with the share of public housing supply specified in the 12 th "Five-Year Plan".The results show that,given the current eligibility requirements in those cities,the share of lowincome households that need public housing in a city varies between 12%and 32%,and there is a significant variation among different cities.The supply-demand ratio of public housing in the 7 major regions varies between 0.6 and 1.9,which indicates a serious mismatch between the public housing construction task(supply) assigned by the central government and the size of households that are eligible for those public housing(demand).At the end of the paper,we propose a technique called "coverage ratio indifference curve" which can convert the eligibility requirement to the household coverage ratio of public housing,or from the latter to the former.The estimation method and technique can be used as quantitative support tools for public housing policies.
