广西农民收入的地区差异及其收入来源分解

Guangxi farmer income's district difference and income origin decomposition

文章根据2011年广西各地的农民纯收入数据,运用基尼系数的定义以及收入来源分解公式,度量了广西农民收入的地区差异以及对该差异进行收入来源分解。结果表明,广西农民收入的地区差异要低于全国省际间水平,工资性收入在总收入中的比重偏小,家庭经营性纯收入的地区差异最小,财产性收入是唯一能扩大地区收入差距的收入来源,转移性收入能降低地区间的收入差异,不过由于对总体不平等的贡献较小,其作用还有待进一步加强。

Based on the data of the Guangxi rural residents’ net income of 2011,the paper gets the Gini coefficient which is used to measure the regional income gap in rural Guangxi and decomposes the gap according to the income sources.The result shows that the regional income gap in rural Guangxi is smaller than the China’s inter-provincial’,the proportion of the salary income is smaller than the outer provincial’,the regional gap of the family business net income is smallest among the all income sources,the financial income is the singal source which can expand the regional income gap and the transferred income can lessen the regional income gap but its effect is weak today because of its small contribution to the overall reginal income gap.
