[摘　要]　利用“住房压力指数”指标计算2005~2009年北京、上海、武汉和重庆四个城市的住房压力，得出近几年四个城市住房压力的总体趋势、四个城市不同收入水平家庭住房压力的具体情况以及2009年四个城市住房压力比较，最后得出一个重要结论：在我国，随着恩格尔系数达到小康或富裕阶段，住房逐渐替代食物在消费支出中的核心地位，即住房压力指数可以替代恩格尔系数作为衡量家庭经济压力大小、富裕程度、幸福程度以及城市贫富差距的重要指标，同时将住房压力指数命名为“任-金”系数。

Abstract: The housing pressure of Beijing, Shanghai, Wuhan and Chongqing from 2005 to 2009 are measured by housing pressure index. Trend of housing pressure of the four cities, housing pressure of families of different income level of the four cities and the comparison of housing pressure of the four cities in 2009 are analyzed. Finally we got an important conclusion: the housing gradually replaces food and becomes the core of consumption when Engel coefficient reaches well-off level or wealthy level in China, housing pressure index replaces Engel coefficient and becomes the important indicator measuring family economic pressure, wealth, happiness and urban gap between the rich and the poor, and the housing pressure index is called Ren-Jin coefficient.

Key words: housing pressure; housing pressure index; Ren-Jin coefficient; Engel coefficient
