改革以来全国总体基尼系数的演变及其城乡分解

China's Overall Gini Coefficient since Reform and Its Decomposition by Rural and Urban Areas since Reform and Opening-up

改革以来,全国总体基尼系数、农村和城镇基尼系数基本上都处于持续上升的态势,且表现出明显的阶段性,这一阶段性特征与改革的阶段性高度吻合;全国总体基尼系数自1992年以来一直大于或等于0.4;城镇基尼系数及其贡献率增长最快,目前是全国总体基尼系数的首要影响因素;城乡差距及其贡献率波动性较大。

China's overall Gini coefficient and Gini coefficients for rural and urban areas have basically both risen constantly since reform. The different stages characterizing their rise are a close fit with the different stages of reform. The overall Gini coefficient has been over 0.4 since 1992. The Gini coefficient for urban areas and its contribution ratio have risen fastest and constitute a major factor affecting the overall Gini coefficient. The gap between the rural and urban Gini coefficient and their contribution ratio shows considerable fluctuation.
