摘要
贫困山区农户生计问题为退耕还林工程可持续发展带来了严峻挑战。本文基于甘肃省会宁县的农户(包括退耕户和非退耕户)调查数据,采用双重差分法(DID)对退耕还林工程的经济效益进行评估。结果表明:退耕还林政策存在处置效应即退耕还林政策对退耕户家庭收入具有显著的负面影响,退耕还林工程使得退耕户收入下降近2000元;差分回归模型分析结果进一步证实了DID方法的研究结论。为实现退耕还林工程的可持续性,建议大幅度提高农户退耕还林的补贴额度,延长退耕还林补贴款年限,建立退耕还林补贴政策的动态调整机制,保证退耕还林工程发挥正的经济效应。
The livelihood problems in poor mountainous areas brought severe challenges for the sustainable development ofthe Grain-for-Green Program. Based on the survey data from rural households （including farmers in and not inGrain-for-Green Program） in Huining County of Gansu Province, this paper evaluated the economic benefits with theDifference in Difference method （DID）. The results showed that the policy of the Grain-for-Green Project has a significantnegative impact on the household incomes of returning farmers. On average, the program reduced the income of returningfarmers by nearly 2,000 yuan. The difference regression model further confirmed the conclusion. In order to ensure thesustainability of the Grain-for-Green Program, this paper proposed to increase the allowance of returning farmland to forestsignificantly and extend the years of subsidies and establish a dynamic adjustment mechanism for the subsidy policy toensure a positive economic effect.
