摘　　要：新时期我国不平等问题表现出新的特征,传统的单一维度的不平等已经无法反映现今不平等问题的多维性特点。本文将量化不平等的视角从一维拓展到多维,基于单维不平等合成多维不平等等三种方法测度了收入、教育和医疗多维不平等程度,同时还对多维不平等指数进行了分解。测算结果显示,2010—2014年,我国社会整体的多维不平等程度有所提高,收入不平等依旧是贡献程度最大的单维不平等。本文得到的一个重要政策启示是认识和解决不平等问题必须注重单一维度和多维相结合;收入差距缩小并不代表多维不平等的同步改善,应对民生领域,特别是教育、医疗领域制定有针对性的政策,进一步缩小差异,以避免多维不平等程度的加深。In the new period,inequality in China has new features,and traditional single-dimension inequality is unable to adapt to the multidimensional nature. This paper extends the perspective of quantitative inequality from one dimension to multiple dimensions,measures the multidimensional inequality of income,education and medical treatment using three methods, and gives the decomposition of multidimensional inequality index. It shows that the multidimensional inequality in China has improved from 2010 to 2014. The income inequality is still the one with the biggest contribution. The suggestion is that it is important to combine single dimension inequality with multidimensional inequality for understanding and solving the inequality problem. The narrowing of income gap does not mean the simultaneous improvement of multidimensional inequality. It should formulate targeted policies for people＇s livelihood,especially in the fields of education and medical care to reduce the differences and avoid deepening the multidimensional inequality.
