摘要:

草原牧区的发展对于我国畜牧业而言具有非常重要的战略意义,为了促进牧区的可持续发展和牧民增收,我国政府于2011年开始实施草原生态补偿政策,在此政策背景下,基于16篇实证研究的3099个样本,运用Meta分析和累积Meta分析方法,探讨了政策实施以来影响牧民收入的重要因素,并分析了这些因素的影响作用随时间的变化趋势。研究结果表明,显著促进牧民收入的因素有牧民受教育程度、家庭劳动力数量、牲畜养殖规模、草场承包面积;其中牧户最为关注的因素有草场承包面积和牲畜养殖规模;而随着政策实施,牲畜数量的影响作用明显增加,其他因素都在减弱;很多变量都存在异质性,其中家庭劳动力数量和草场面积的异质性来源主要是地区因素,除此之外还有政策实施时间和抽样方式的影响。

Abstract:

The development of grassland pastoral areas is of great strategic significance for animal husbandry in China. To promote the sustainable development of pastoral areas and increase the income of herders, the Chinese government implemented the Grassland Ecological Compensation Policy in 2011. Based on 3099 samples identified from 16 empirical studies, we conducted a meta-analysis and cumulative meta-analysis to explore factors affecting herdsmen’s income since the implementation of this policy, and analyzed the effects of certain factors over time. The factors significantly increasing herders’ income included education level, amount of household labor, number of livestock, and the leased area of grassland. The main concerns of herders were the grassland area and the number of livestock. Since the implementation of the policy, the effect of the quantity of livestock has increased significantly, while the effects of other factors have decreased. Many variables showed a degree of heterogeneity. The heterogeneity of household labor and grassland area was mainly due to regional factors, the policy implementation time, and the sampling methods.
