不同就业类型农户的收入差距及其对总体不平等的贡献

The Income Inequalities of Different Employment Type Household and Theirs Impaction to Overall Inequality

本文利用天津市2002—2008年农村住户调查数据,采用基于相对剥夺理论的基尼系数子群分解方法,研究了四类农户:纯非农户、非农兼业户、农业兼业户和纯农户,群内和群间的收入差距及其对总体不平等的贡献。研究结果表明:天津市农村内部收入差距较大,不同就业类型农户间的相对剥夺差异较大,每个子项对总体收入差异的贡献是人口份额、收入份额和相对剥夺这三个因素共同作用的结果,群内贡献和群间贡献之比大约为3∶7。

Based on the survey data of Tianjin rural household from 2001 to 2008, this paper studies the within-group and between-group income gap of four type＇s rural households （net off- farming household, mainly off-farming household, mainly farming household, net farming household） and their contribution to overall inequality using Gini index subgroup decomposition method based relative deprivation theory. The result shows that the income inequality of overall rural household, the relative deprivation between and within two type＇s rural household is rela-tive more; the contribution of each component to overall inequality is the combined action＇s consequence of population share, income share and relative deprivation; the ratio of within-group contribution and between-group contribution to overall inequality is about 3 ： 7.
