中文摘要：

运用Watts多维度贫困指数，从收入、知识和健康三个维度测算了我国1990年、1997年和2003年的多维度贫困，并对引起贫困状况变化的原因进行了夏普里分解。测算结果表明，从1990—2003年，我国多维度贫困出现大幅下降，其中，收入贫困下降最多，健康贫困下降最少。同时，近年来在我国整体义务教育水平提高的同时，有一部分人的教育年限却在下降，说明教育发展很不均衡。

The paper analyses the reasons of poverty changes using Shapley decomposition. The result shows that, the Watts multi-dimensional poverty index decreases deeply in 1990 to 2003. Thereinto, income poverty index descends the deepest, and the heath poverty index declines the least. Recently, while the genaral educational level has improved greatly, the educational time of some people is declining, which shows that the development of education in China is in imbalance.
