摘要
本文发展出一个衡量收入差距的基尼系数计算公式,并分解出构成总收入的各类收入基尼系数及其对总收入差距的贡献率的计算方法。利用《中国统计年鉴》2003—2010年按收入五等份分农村居民家庭基本情况的有关数据,测算出农民各类收入的基尼系数及其分解结果和贡献率情况。实证研究结果表明,近年来我国农民收入实现了持续快速增长,特别是财产性收入和转移性收入增长尤为迅速,农民纯收入中工资性收入和家庭经营纯收入占据了绝对份额;我国农民收入差距呈现出稳中有降的态势,各类收入中财产性收入差距最大,工资性收入和家庭经营纯收入差距对农民纯收入差距的贡献最大。
This paper develops a simple calculation formula of Gene Coefficient, and decomposes the calculation formula of Gene Coefficient about all kinds of income which make the total income, as well as gets a calculation method of the contribution rate about various types of income gap on the total income gap. We use the data of basic situation of rural dweller families in five equal parts of income in ＂China Statistical Yearbook＂ from 2003 to 2010, measure and calculate the Gene Coefficient, decomposition results and contribution rate about all kinds of income. The empirical study shows that farmer income grew quickly and continuously in recent years, and the property income and transfer income grew rapidly especially. The salary income and operating net income of the family occupied the absolute share in net income, The income gap among famers showed a stable slow - down. The gap of property income was the largest among all kinds of income. Wage income and operating net income had the greatest contribution to farmers＇ net income gap.
