【摘要】 农村第二轮土地承包陆续到期延包在即，妥善处理人地关系、促进人地要素高效流动至关重要。基于广东、广西两个地区894户农村家庭的微观调研数据，构建“农村家庭结构转型—劳动力迁移—土地流转”理论框架，综合运用Probit、OLS等模型进行实证检验，并引入中介效应分析劳动力迁移的传导作用。趋势性分析发现，当前农村家庭结构呈现三种转型规律:规模结构小型化，“大家庭”向“小家庭”转型;形态结构裂解化，“同爨共炊”向“析箸分家”转型;居住结构离散化，“聚耕而居”向“离工而散”转型。实证结果表明，农村家庭结构转型降低了对自营土地的依赖性。家庭规模结构小型化、形态结构裂解化以及居住结构离散化显著促进土地流转，且劳动力迁移在其中发挥中介效应。异质性分析表明，农村青年和男性户主的家庭在结构转型后表现出更强的土地流转倾向。探究农村家庭结构转型、劳动力迁移与土地流转的动态关系，为优化人地要素配置提供理论依据。更多还原

【Abstract】 As the contracts of the second round of rural land contracting are gradually expiring and about to be extended,properly handling the relationship between people and land and promoting the efficient flow of humanland factors have become crucial. Based on micro survey data from rural households in Guangdong and Guangxi(894 households), this paper constructs a theoretical framework of “ rural household structural transformationlabor migration-land transfer ”, employs Probit, OLS, and other models for empirical testing, and introduces mediation analysis to examine the transmission role of labor migration. Trend analysis shows that current transformations in rural household structure present three patterns: miniaturization of household size structure,characterized by the shift from “large families” to “small families”; fragmentation of household form structure,characterized by the shift from “living and eating together” to “separate households with independent kitchens”;and dispersion of residential structure,characterized by the shift from “ living together and farming locally” to“ working away and living apart”. Empirical results indicate that rural household structural transformation reduces dependence on self-operated land. The miniaturization of household size structure, fragmentation of household form structure,and dispersion of residential structure all significantly promote land transfer,with labor migration playing a mediating role. Heterogeneity analysis further shows that,after household structural transformation,rural youth and male household heads display a stronger tendency toward land transfer. Exploring the dynamic relationships among rural household structural transformation, labor migration, and land transfer provides a theoretical basis for optimizing the allocation of human-land factors.更多还原
