黄河流域农村人口老龄化对农业生态效率的影响OA
The Impact of Rural Population Aging in the Yellow River Basin on Agricultural Ecological Efficiency—An Analysis of the Mediating Effect Based on Agricultural Land Management Efficiency
根据2012-2021年黄河流域各省(区)的面板数据,首先利用超效率SBM模型测算该流域农业生态效率,再实证分析农地经营效率在农村人口老龄化对农业生态效率影响的中介效应.结果表明:①黄河流域农业生态效率值均大于1,整体表现出曲折发展的趋势.区域中,上游的农业生态效率均值最高,中游相对较低,下游最低.②农村人口老龄化对黄河流域农业生态效率和农地经营效率均有显著的正向作用.③农地经营效率在农村人口老龄化对农业生态效率的影响中具有部分中介作用,农村人口…查看全部>>
This article uses provincial panel data from the Yellow River Basin from 2012 to 2021.Firstly,the super efficiency SBM model is used to measure the agricultural ecological efficiency in the Yellow River Basin.Then,the intermediary effect model is used to empirically an-alyze the mediating effect of agricultural land management efficiency on the impact of rural population aging on agricultural ecological efficien-cy.The results showed that:① The agricultural …查看全部>>
