Many economists have argued that income is an inadequate indicator of welfare. In this paper, we conduct a multivariate analysis of the distribution of individual welfare in China at three selected time points: 1991, 1997 and 2006. Instead of using income as the only welfare indicator as in most distributional analyses, we explicitly consider the role of health in welfare distribution. We adopt the Naga and Geoffard (2006) decomposition method by which we can decompose a bidimensional welfare inequality index into two univariate Atkinson-Kolm-Sen indices that measure the inequalities in health and income, and a third term that measures the contribution from the joint distribution of the two attributes to total inequality. We show that the third term might be used as an alternative to the concentration index to measure the income-related inequality in health.
许多经济学家认为，收入是福利的一个不充分指标。在本文中，我们对中国在三个选定时间点（1991 年、1997 年和 2006 年）的个人福利分布进行了多元分析。与大多数分配分析中仅将收入作为唯一福利指标不同，我们明确考虑了健康在福利分配中的作用。我们采用了 Naga 和 Geoffard（2006）的分解方法，通过该方法，我们可以将二维福利不平等指数分解为两个衡量健康和收入不平等的单变量 Atkinson-Kolm-Sen 指数，以及衡量两个属性联合分布对总不平等的贡献的第三个术语。我们表明，第三个术语可以用作集中指数的替代指标，以衡量与收入相关的健康不平等。
