城市居民住房承受能力测度研究——剩余收入视角

借鉴扩展线性支出系统模型确定家庭食品、衣着、家庭设备用品及服务等非住房基本消费支出的基础上，运用剩余收入法测度了2003—2008年武汉市七种不同类型家庭的住房承受能力。剩余收入法测度结果能反映出不同类型家庭住房承受能力的具体差距，显示出武汉市中等偏下收入及以下收入家庭面临住房承受能力问题，并且收入越低住房承受能力问题越突出，结果比传统比率法更具有说服力。而比率法测度显示中等偏上户及以下家庭面临住房承受能力问题，扩大了存在住房承受能力问题的家庭范围。运用剩余收入法可以定量地测度各类家庭住房承受能力的大小和绝对差距，有助于确定城市中低收入家庭住房补贴的对象及标准，制定我国公共住房销售、租赁政府指导价格，促进完善住房保障政策。

Measuring the Housing Affordability of Urban Residents——Based on Residual Income

The purpose of this paper is to measure the housing affordability of different households in Wuhan from 2003 to 2008, which the costs of the non-housing necessities, including food, clothing, household facilities, articles and services, and so on, are dedueed by the Extended Linear Expenditure system （ELES）. The empirical study shows that the lower middle income households and below have housing affordability problems for a standardized new home, and the lower income is associated with weaker housing affordability. The outcomes of residual measures are more persuasive than the ratio measures, whieh shows the housing affordability problems of upper middle income households and below are more prominent, and scales up the housing affordability of households. The Residual Income can be used to quantitatively measure various types of family housing affordahility and the absolute size of the gaps, help to define the target households and standards of housing subsidies, determine the sales and leasing guide price of public housing, and promote the housing security policy.
