不同模式农地整治对农民生活满意度的影响差异研究——基于生计资本总量和结构的中介效应分析

Impact of Rural Land Consolidation in Different Modes on Farmers'Life Satisfaction:Mediating Effect of Quantity and Structure of Livelihood Capital

基于可持续生计框架,选择生计资本总量和结构作为中介变量,采用“双重差分-中介效应”模型和农户调查面板数据,实证分析了不同模式农地整治对农民生活满意度的影响效应及其作用机理。结果表明:(1)地方政府主导模式和新型农业经营主体主导模式不仅对农民生活满意度具有显著的直接正向效应,而且通过增加生计资本总量和改善生计资本结构,进而对农民生活满意度产生显著的正向间接效应;(2)相比于地方政府主导模式,新型农业经营主体主导模式更能显著增加生计资本总量和改善生计资本结构,进而更能显著提升农民生活满意度;(3)地方政府主导模式通过增加生计资本总量提升农民生活满意度的作用更强,而新型农业经营经营主体主导模式通过改善生计资本结构提升农民生活满意度的作用更强;(4)通过winsorize缩尾处理进行稳健性检验,证实研究结果具有相当的稳健性。

Based on the sustainable livelihoods framework,livelihood capital quantity and structure were selected as mediating variables,and then difference-in-difference model and mediation-effect model were employed to analyze the impact mechanism of rural land consolidation projects(RLCP)in different modes on farmers'life satisfaction.The result indicated that:(1)Local government-dominant mode and new agricultural management entities-dominant mode RLCP had significant positive direct effect on farmers'life satisfaction,and also had significant positive indirect effect on farmers'life satisfaction by increasing livelihood capital quantity and improving livelihood capital structure.(2)Compared with local government-dominant mode RLCP,new agricultural management entities-dominant mode RLCP had significant positive effect on farmers'life satisfaction by significantly increasing livelihood capital quantity and improving livelihood capital structure.(3)The mediating effect of livelihood capital quantity was larger than that of livelihood capital structure in local government-dominant mode RLCP,while the mediating effect of livelihood capital structure was larger than that of livelihood capital quantity in new agricultural management entities-dominant mode RLCP.(4)Winsorization approach was adopted to carry out robustness tests,which confirmed the main estimation results were considerably robust.
