【摘要】：【目的】研究退耕还林工程对农户收入不平等的影响,以检验退耕还林工程目标的实现情况,为政府相关部门调整退耕还林工程后续政策及实施其他生态恢复项目提供决策依据。【方法】基于四川、河北、陕西等6省(区)15个案例县1 158个样本农户1995—2012年的平衡面板数据,考虑参与退耕还林工程的总体影响和边际影响,建立样本农户总收入决定方程;以基尼系数、泰尔-L指数和泰尔-T指数作为衡量收入不平等的指标,采用Shapley值分解法对样本农户的总收入决定方程进行分解,全面系统评估退耕还林工程对农户收入不平等的影响。【结果】经验性结果显示,样本农户是否参加退耕还林工程和参加退耕还林工程面积对总收入的影响均为正且在1%水平上显著。1999—2012年,样本农户是否参加退耕还林工程和参加退耕还林工程面积对总收入基尼系数的贡献率呈先升后降的趋势,贡献率最高为2008年,是否参加退耕还林工程和参加退耕还林工程面积的贡献率分别为3.04%和4.55%;在变化趋势上,退耕还林工程对样本农户总收入泰尔-L指数和泰尔-T指数的贡献与对基尼系数的贡献基本一致。【结论】实施退耕还林工程增加了样本农户的总收入,但拉大了样本农户的总收入不平等。因此,就生态恢复工程对农户收入不平等可能产生的影响而言,有必要引起高度关注,实现生态恢复、农民增收与分配公平的多赢。
[Abstract]:[Objective] to study the project of returning farmland to forest on Farmers' income inequality, in order to realize the inspection of returning farmland to forest project objectives, to provide decision-making basis for restoration projects to the relevant government departments to adjust the project follow-up policy and implement other ecological. [method] Based on Sichuan, Hebei, Shaanxi and other 6 provinces (regions) balance the panel data of 15 cases of 1158 sample households from 1995 to 2012, consider participating in the project of returning farmland to forest overall effect and marginal effect, the establishment of the sample total income equation; by the Gini coefficient, Theil index and Theil index -L -T as a measure of income inequality index, using Shapley value decomposition method of sample total income the farmer decided equation decomposition, on the comprehensive evaluation system of the project of returning farmland to forest on Farmers' income inequality. [results] the empirical results show that the sample farmers participate in returning farmland to Effect of forest engineering and in the project of returning farmland to forest area of the total income are positive and significant at the 1% level.1999 - 2012, sample farmers whether to participate in the project of returning farmland to forest and in returning farmland to forest project area on the total income of the Gene coefficient contribution rate decreased, the contribution rate was the highest in 2008 whether to participate in the project of returning farmland to forest, and participate in the project of returning farmland to forest area accounted for 3.04% and 4.55%; in the trend, the contribution of returning farmland to forest project to household total income Theil index and the Theil index -L -T and the Gene coefficient with basically the same. [Conclusion] the implementation of the project of returning farmland to forest increased the total income of the sample households, but widening the total income inequality of sample farmers. Therefore, ecological restoration on Farmers' income inequality likely impact, it is necessary to pay close attention to, to achieve ecological Recovery, farmers' income increase and distribution fair win.
