摘　　要：对新发展的极化测度指标及其分解公式做进一步的分解,并分析了中国农村地区间人均纯收入的极化及其变动。结果表明:2006年之前极化程度波动上升,随后逐年下降;从收入来源的角度来看,工资性收入对极化程度的贡献最大,而财产性收入和转移性收入对极化程度的贡献逐年提高;收入变动的结构效应会导致极化程度的提高,而集中效应会导致极化程度的降低。This paper analyzes the regional income polarization and its change in rural China using the newly developed polarization measure index and the corresponding decomposition formulas.The results show that： Firstly,the degree of polarization increased with fluctuation before 2006,then decreased year by year;Wage income played the most important role in the degree of polarization,in contrast,the contribution of property income and transferability income increased year by year.The structure effect of income change would raise the polarization while the concentration effect played the opposite role in the changes in polarization.
