摘　　要：探究农地转入对农户黑土地保护性耕作行为的影响,为政府制定促进农户采纳黑土地保护性耕作技术相关政策提供参考。本文利用黑龙江省三江平原典型县市的农户微观调研数据,运用多元有序Logistic回归模型、中介效应模型等方法探究农地转入对农户黑土地保护性耕作行为的影响效应及影响机制,研究结果表明:1)农地转入对农户黑土地保护性耕作行为有显著正向作用,具体表现为转入面积、转入费用、转入市场化程度对农户黑土地保护性耕作行为具有显著正向作用。2)农地转入、转入面积及转入市场化程度能够通过缓解农地细碎化显著促进农户黑土地保护性耕作行为。3)相对于小农户,农地细碎化在农地转入对规模户黑土地保护性耕作行为影响中的中介作用更显著。据此本文从优化农地流转政策、财政与金融激励并举和推进“小田变大田”改革三个方面提出了对策建议。Investigating the inffuences of agricultural land transfer on farmers’conservation tillage practices of black soil farmland can provide valuable references for the government in formulating relevant policies to promote farmers’adoption of black soil farmland conservation tillage techniques.Based on a micro-survey data of farmers from typical counties and cities in the Sanjiang Plain of Heilongjiang Province,this paper explored the impacts and mechanism of agricultural land transfer on farmers’conservation tillage behaviors of black soil farmland by the multivariate ordered Logistic regression model and the mediating effect model.Results indicate:1)Agricultural land transfer has a signiffcant positive effect on farmers’conservation tillage behaviors of black soil farmland.Speciffcally,the transfer area,transfer cost,and the degree of marketization of transfer have significant positive effects on farmers’conservation tillage behaviors of black soil farmland.2)Agricultural land transfer,the transfer area,and the degree of marketization of transfer can significantly promote farmers’conservation tillage behaviors of black soil farmland by alleviating land fragmentation.3)Compared with small-scale farmers,the mediating role of land fragmentation in the inffuence of agricultural land transfer on the conservation tillage behaviors of large-scale farmers is more significant.Based on the above results,this paper puts forward some countermeasures and suggestions,including optimizing agricultural land transfer policies,implementing both ffscal and ffnancial incentives,and promoting the reform of“converting small ffelds into large ffelds”.
