退耕还林政策实施对退耕者经济纯效益的影响评价——以甘肃4个退耕还林试点县为例

在总结前人对退耕还林政策实施效果评价的基础上,从退耕者所得到的经济效益角度,评价退耕还林政策的方法,并以甘肃4个退耕还林试点县为例进行实证研究.具体步骤为:首先,构建评价所需的指标体系,然后通过实地调查得到所需指标数据,再运用费用效益法估算政策实施前后退耕者所得纯经济效益.最后,运用比较分析法对比政策实施前后退耕者所得纯经济效益的大小,从而实现退耕还林政策对退耕者经济纯效益的影响评价.

Evaluation on the Effects of Implementing the Policy of Returning Land from Farming to Forestry and Grassplot on Farmers' Pure Economic Returns——A Case Study in Four Test Regions of Gansu Province

Under the current circumstances of the serious deterioration of ecological environment in China,a series of measures of ecological conservation have been implemented,one of them is the policy of returning land from farming to forestry and grassplot.After summarizing the achievements in researching the effects of implementing the policy of returning land from farming to forestry and grassplot,carried out by many scholars,in this paper the methods of evaluating the increase of farmers' pure economic returns after implementing the policy of returning land from farming to forestry and grassplot are discussed,and a case study on the evaluation of the effects of implementing the policy of returning land from farming to forestry and grassplot on farmers' pure economic returns in 4 test regions of Gansu Province is carried out.The detailed study steps are that the evaluation index systems are developed at first,then the data are collected by field survey,the pure economic returns before and after implementing the policy are estimated using cost-profit method,and the pure economic returns before and after implementing the policy are compared using comparison-analysis method so as to derive the evaluated results of farmers' pure economic returns after implementing the policy of returning land from farming to forestry and grassplot.
