退耕还林对农户收入的影响分析——基于PSM-DID方法

Analysis on the Influence of Returning Farmland to Forest on Farmers' Income—— Based on PSM-DID Method

基于中国家庭追踪调查面板数据,文章利用双重差分倾向得分匹配方法就退耕还林政策对农户的收入效应进行了研究。实证结果表明:退耕还林政策对农户的财产性收入存在显著正效应,但总体增收效果不明显,甚至存在负效应,而非农就业能有效提高各种类型收入进而提高其总收入。这为下一步完善退耕还林政策、更好地解决农村贫困问题提供了决策参考。

Based on the panel data of China Family Panel Studies,this paper used the dual differential propensity score matching method to study the income effect of farmers on the policy of returning farmland to forest.The empirical results showed that the policy of returning farmland to forest had a significant positive effect on the property income of farmers,but the overall income increase effect was not obvious,and even had a negative effect.Non-agricultural employment could effectively increase various types of income and increase their total income.This provided a decision-making reference for the next step of improving the policy of returning farmland to forest and better solving the problem of rural poverty.
