摘要
通过提出洛伦兹曲线模型构造方面一个基本定理,获得了若干种拟合效果良好的洛伦兹曲线模型,与目前经济理论文献中的模型比较,这些模型能表达更灵活的曲线,实践中可能获得更理想的拟合效果。使用新引进的模型,对2000—2006年湖北省农村收入不平等、贫困、两极分化进行的测算表明,近几年湖北省农村人口的收入不平等逐年扩大,贫困程度逐年增加,2004年达到峰值,以后两年有所改善。上述方法除可以用于监控我国农村人口的收入分配外,也可以用于我国各地区、各行业、各种人口结构等群体内的收入分配分析。
Based on a fundamental theorem raised in the construction of the classic Lorenz curve,we developed several Lorenz curve models characterized by a high level of goodness-of-fit.Compared with other models in the current literature on economic theory,these models may offer a more flexible curve and achieve better goodness-of-fit in practice.Using these models,we calculated inequality in income distribution,poverty and polarization in the rural areas of Hubei between 2000-2006.We found that the rural income gap widened over this period and the level of poverty worsened,reaching a peak in 2004.The following two years saw a slight improvement.The new models outlined in this paper can not only be used in monitoring rural income distribution in China,but can also help us analyze income distribution in different regions,industries and demographic groups.
