摘要

为定量评价"退牧还草"生态政策对北方农牧交错区农户收入的影响,采用倾向得分匹配法处理样本内生性问题,对宁夏盐池县进行了实证分析。结果表明:在剥离社会经济因素的影响下,"退牧还草"生态政策的实施对农户养殖业收入有提升作用,这种政策实施收益是通过农户生产方式转变的选择来实现的,但政策实施对种植业和非农收入的影响并不明显。通过匹配分析发现,近几年农户总收入的增加并不能仅归因于生态政策的实施,而是社会经济发展、粮食价格变化、思想观念转变和通货膨胀等多种因素综合影响的结果。

Abstract

In order to quantitatively evaluate the effect of ecological policy of Returning Grazing Land to Grassland on farmers' income in the farming-pastoral zone on the north of China, Yanchi Country is selected as the study area. We empirically analyzed the effects of ecological policy of "Returning Grazing Land to Grassland" on farmers' income by using the propensity score-matching method to deal with the endogenous problem of sample. The result showed that the "Returning Grazing Land to Grassland" can improve the farming income under the condition of ignoring social and economic elements, and the farmers gained the implementation of the policy of income by changing their mode of production. But the policy show little effects on planting and non-agricultural income. It was founded out that the increase of farmers' income was attributed to the comprehensive effects of the social and economic development, the price change of foods, the transformation of minds and the inflation, but not the implementation of the ecological policy. This research can provide theoretical basis for the implementation and improvement of Returning Grazing Land to Grassland policy in Yanchi and other similar areas.
