基于因变量方差分解法的乡村居民收入差距影响因素研究

Analyse the Influencing Factors of Income of Rural Residentsbased on Independent Variables Variance Decomposition

乡村居民的收入来源主要是农业和非农收入,因此农业和非农收入的差距就决定了乡村居民收入差距的基本格局。本文提出因变量方差分解法,可以定量分析出解释变量对以方差衡量的居民农业和非农收入差距的贡献,由此可发现有政策含义的影响因素。研究发现:家庭人均耕地数量,农业条件,农民是否兼业等对农业收入差距贡献较大;交通条件,性别,父母收入状况,信息交流状况,是否兼业等对非农收入差距贡献较大。

Agriculture income and non-agriculture income are primary income sources of rural residents.So,the difference between these two incomes determines the income gap level of rural residents.We use the method—independent variables variance decomposition—to do the analysis.This method can do a quantitative analysis to find the contribution of the independent variables to the income difference,which measured by the variance between the agriculture income and non-agriculture income.Thus we can see the factors which are valuable to the government policy.In our research,we find the average amount of farmland,agriculture production condition,and part-time job have significant influence on the agriculture income of rural residents.The transportation condition,gender,parents'income,information transparency,and part-time job have a significant influence on non-agriculture income.
