摘　　要：本文使用全国数据分析了改革以来中国城镇居民收入差距的总体特征,并基于天津市典型调查数据,应用基尼系数分解方法研究了近20年来城镇居民收入差距的变动轨迹及其影响因素。针对基尼系数的收入构成分解研究显示,工资性收入的分布状况基本上决定了城镇居民收入差距的变动趋势,财产性收入和经营性收入的分配状况趋于相对均等化,转移性收入对总收入差距的平抑作用被大大削弱,社会保障体系在覆盖面扩大的同时可能存在识别和瞄准上的方向性偏误;而从人口特征角度进行的基尼系数分解研究则显示,居民行业差别、就业性质以及受教育程度成为影响城镇居民收入差距最重要的三大因素。This paper used the national data after reform to analyze the overall characteristics of China＇ s cities income gap, then based on the Tianjin typical survey data used the method of Gini Coefficient Decomposition to research the change path and the influencing factor of cities income gap for near 20 years. Gini coefficient income structure decomposition indicats that： wage income＇ s distributed condition basically decides the tendency of cities income gap change. Property income and managerial income＇ s assignment condition tends to equalization. Transferability income＇ s holding down function to the gross income disparity has been wreaked guish with coverage promotion. The employment nature, greatly, social security system possibly exists bias error to distineducation level and the profession category are the most important three big factors which affect income gap among cities inhabitant. Finally, the article gave the policy suggestion.
