西北干旱地区农民收入差异实证分析

Empirical analysis of farmers' income difference in the northwest arid land

以甘肃民乐县为样本,运用基尼系数测度指标,分析了农民收入的差异程度。基尼系数分解结果显示:经营性收入将会导致收入差异进一步扩大,工资性收入比重的增加将会进一步减小收入差异;进一步利用2007和2009年两年的问卷调查数据,通过面板数据(Panel Data)进行回归,结果显示:劳动力、耕地地块数、种植结构、是否签订马铃薯协议以及地区特征等因素对收入影响较为显著。因而要减少或消除农村地区间家庭收入的不平等,在保证经营性收入稳定增长的基础上,应大力提高获得工资性收入的机会。

Minle county in Gansu province was taken as the sample,the farmers＇ income difference degree was analyzed by using the Gini coefficient measure index.Gini coefficient decomposition results showed that operational income would lead to further income difference,the increase in the proportion of salary income would further reduce income difference.Based on the survey data in 2007 and 2009,and using the panel data for regression analysis,the results showed that the labor,the number of cultivated land,planting structure,potato agreements,regional characteristics and other factors had significant impacts on the farmers＇ income.Thus it is necessary and important to substantially improve the opportunity of getting salary income in order to reduce and eliminate the family income inequality in rural areas on the basis of the guaranteed operational income.
