本文的目的是提出一种不等式分解方法--两阶段嵌套Theil分解方法，它是普通一阶段Theil分解方法的推广.该方法类似于方差分析（ANOVA）中的两阶段嵌套设计。它考虑了一个国家的三级等级结构：地区-省-区，并将基于区一级平均收入的泰尔指数衡量的总体地区不平等分解为三个组成部分：地区间、省间和省内不平等组成部分。省内部分是每个省的省内收入不平等的加权平均数，而省间部分是每个地区内省间收入不平等的加权平均数。该方法以地区而不是省份作为衡量区域收入不平等的基本区域单元，从而可以在一个连贯的框架内分析省内不平等以及省与省之间和地区之间的不平等对总体区域收入不平等的贡献。本文将两阶段嵌套Theil分解方法应用于中国和印尼的地区收入和人口数据，探讨了中国和印尼地区收入不平等的影响因素。
The objective of this paper is to present an inequality decomposition method, the two-stage nested Theil decomposition method, which is an extension of the ordinary one-stage Theil decomposition method. The method is analogous to a two-stage nested design in the analysis of variance (ANOVA). It considers the three-level hierarchical structure of a country: region-province-district, and decomposes the overall regional inequality, as measured by Theil indices based on district-level mean incomes, into three components: the between-region, between-province, and within-province inequality components. The within-province component is a weighted-average of within-province income inequalities for each province, while the between-province component is a weighted-average of between-province income inequalities within each region. The method uses districts as a basic regional unit to measure regional income inequality, rather than provinces, and thus can analyze the contribution of within-province inequalities as well as between-province and between-region inequalities to the overall regional income inequality in a coherent framework. This paper applies this two-stage nested Theil decomposition method to district-level income and population data in China and Indonesia and explores the factors of regional income inequality in China and Indonesia.
