摘要
整体结构位置和二元关系程度是社会网络的“质”和“量”特征,区分农户的结构和关系嵌入维度,有助于揭示社会嵌入与化肥施用之间的“黑箱”。本文基于社会嵌入理论构建农户化肥减施行为的嵌入逻辑,利用辽宁省1011户粮食种植农户的实地调研数据,运用Heckman两阶段模型进行实证分析,揭示了社会嵌入对农户化肥减施行为的影响机理。研究结果表明:①社会嵌入有利于农户的化肥减量行为,但结构嵌入和关系嵌入间存在化肥减量选择和减量结果的影响差异,结构嵌入相较于关系嵌入拥有更强的化肥减量效应,“弱关系”更有利于实现农户的化肥减量行为。②社会嵌入的化肥减量作用因农户分化类型而呈现差异,结构嵌入和关系嵌入能提高小农户和兼业户选择减量施用化肥行为的可能性,但关系嵌入能够促进其化肥持续减量。仅结构嵌入和关系质量能提高规模户和纯农户选择减量施用化肥的可能性,并促进其化肥持续减量。关系质量型嵌入适用于小而兼型农业生产经营的化肥减量,结构质量型嵌入适用于大而专型农业生产经营的化肥减量。因此,加强社会网络的嵌入结构建设和制定更有针对性的社会化减量路径,对拓展农业减量社会化、促进农业绿色高质量发展具有重要意义。
The overall structural location and the degree of dual relationship are the“quality”and“quantity”characteristics of the social network.Distinguishing the structure and relationship embedding dimensions of farmers is helpful to reveal the“black box”between social embedding and fertilizer application.Based on the social embeddedness theory,this paper constructs the embeddedness logic of farmers’fertilizer reduction behavior,uses the field survey data of 1011 grain planting farmers in Liaoning Province,and uses the heckman two-stage model for empirical analysis to reveal the impact mechanism of social embeddedness on farmers’fertilizer reduction behavior.The results show that:①Social embeddedness is beneficial to farmers’fertilizer reduction behavior,but there are differences in fertilizer reduction selection and reduction results between structural embeddedness and relational embeddedness.Structural embeddedness has a stronger fertilizer reduction effect than relational embeddedness,“weak tie”is more conducive to the realization of farmers’fertilizer reduction behavior.②The role of social embeddedness in fertilizer reduction varies according to the type of farmer differentiation.Structural embeddedness and relational embeddedness can improve the possibility of small farmers and part-time workers choosing to reduce the amount of chemical fertilizer,relational embeddedness can promote the continuous reduction of their chemical fertilizer.Only structural embeddedness and relationship quality can improve the possibility of scale households and pure households to choose to reduce the amount of fertilizer,promote the continuous reduction of their fertilizer.Relational quality embeddedness is applicable to the reduction of chemical fertilizer in small and part-time agricultural production and operation,while structural quality embeddedness is applicable to the reduction of chemical fertilizer in large and specialized agricultural production and operation.Therefore,strengthening the embedded structure construction of social network and formulating more targeted socialization reduction path are of great significance to expand the socialization of agricultural reduction and promote the green and high-quality development of agriculture.
