摘　　要：基于2011—2020年中国健康与养老追踪调查数据库中25个省份3231个农户样本的大型微观样本数据,采用再中心化影响函数(RIF)模型,分析退耕还林工程对农户收入差距的影响及其多维异质性特征。研究发现:(1)退耕还林工程能够显著缩小农户收入差距,退耕补助每多发放1%,基尼系数下降0.078,这一结果在替换被解释变量与解释变量后依然稳健;(2)从退耕农户收入差距与非退耕农户收入差距的差异分析结果来看,相较于非退耕农户,退耕农户收入差距更小,其收入分位距与基尼系数均显著低于非退耕农户;(3)从连续退耕与非连续退耕农户的异质性分析结果来看,退耕还林工程对连续退耕农户收入差距的缩小作用强于非连续退耕农户;(4)从异质性分析结果来看,退耕还林工程对农户收入差距的缩小效应在不同受教育程度农户中存在异质性,对受教育程度低的农户影响更明显。⑴Background——How to steadily increase the income of low-income rural households and narrow the income gap of rural households through ecological protection and restoration projects is related to the sustainable development of ecological protection and restoration projects.It is necessary to analyze the impact of the project of returning farmland to forest on the income gap of rural households from a new perspective of the income increase and common prosperity effect of ecological projects,so as to provide a basis for the income increase effect of ecological protection and restoration projects and promote common prosperity.⑵Methods——This paper first proposed the research hypotheses based on the literature review and theoretical analysis.Then,based on the large-scale micro-sample data of 3231 sample rural households from 25 provinces in the China Health and Retirement Longitudinal Study(CHARLS)Database from 2011 to 2020,Using the Recentered Influence Function(RIF)model,this paper analyzed the impact of the project of returning farmland to forests on the income gap of rural households and its multi-dimensional heterogeneity characteristics.⑶Results——First,the project of returning farmland to forests has significantly increased the rural households’income and narrowed the income gap between the rural households.The Gini coefficient decreased by 0.078 for every 1%increase in the subsidy for returning farmland to forests.After replacing the explained and explanatory variables,the Gini coefficient remains stable.Second,the income gap of the rural households who returned farmland to forests was smaller than that of the rural households who did not return farmland to forests,and their income quantile range and Gini coefficient were significantly lower than those who did not return farmland to forests.Third,the effect of the project of returning farmland to forests on narrowing the income gap of the rural households who continuously returned farmland to forests was greater than that of the rural househo
