| 摘 要： | 贫困指数是衡量社会总体贫困程度的指标,在众多的贫困指数中.本文选择具有良好性能的瓦特指数和由此派生出来的脱贫时间指数,分析了我国城镇上个世纪90年代以来的贫困变化趋势.研究发现,城镇贫困在1997年达到高峰,然后逐渐缓和;贫困人口的收入增长在初期能使脱贫时间迅速下降,但边际效果是递减的;贫困人口之间的收入分配不平等延长了脱贫时间:如果贫困人口的初始收入增加,会明显降低脱贫时间.

| Abstract: | The most widely used poverty measures do not show when poverty might be eliminated. As a new poverty measure derived from Watts poverty index, the average exit time is not only distributionally-sensitive, but also has a ready interpretation as the average time to exit poverty with a constant and uniform growth rate. The index is illustrated with data from China. We find that the economic growth can shorten the average exit time, but the marginal effects are decreasing; inequality increases average exit time. |
