农机社会化服务对农户家庭耕地经营规模的影响——来自CLDS的经验证据

Influence of agricultural machinery socialization service on the farmland scale of farmer households:Empirical evidence from CLDS

为探究农机社会化服务对农户家庭耕地经营规模的影响,将农户家庭耕地面积、流转面积和弃耕地面积放在同一分析框架内进行理论机制分析,并利用CLDS2018数据进行了实证检验。结果表明:第一,农机社会化服务对农户家庭耕地面积和弃耕地面积均有显著负向影响,对转入地面积没有显著影响。第二,规模异质性分析表明,农机社会化服务对于规模经营农户的耕地面积和转入地面积具有显著正向影响,对小农户和规模经营农户的弃耕地面积均有显著负向影响,农机社会化服务通过增加规模经营农户的转入地面积增加实际经营的耕地面积,减小了小农户的耕地面积。第三,区域异质性分析表明,农机社会化服务对东、中西部地区的农户家庭耕地面积和弃耕地面积均有显著负向影响,对中西部地区农户家庭的转入地面积具有正向影响,此外,对于东、中西部地区农户家庭弃耕地面积均有显著负向影响。最后根据结论提出完善农机社会化服务供给和加快户籍制度改革。

In order to explore the impact of agricultural machinery socialization service on the farmland scale of farmers’households,the arable land area,transferred area and abandoned farmland area of farmer households were put into the same analysis framework for theoretical mechanism analysis,and the CLDS2018data were used for empirical tests.The results are as follows:First,agricultural machinery socialization service has a significant negative impact on the arable land area and abandoned farmland area of farmer households,but has no significant impact on the transferred area.Second,the analysis of scale heterogeneity shows that the agricultural machinery socialization service has a significant positive impact on the arable land area and transferred area of large-scale farmers,and has a significant negative impact on the abandoned farmland area of small-scale farmers and large-scale farmers.Third,the analysis of regional heterogeneity shows that the agricultural machinery socialization service has a significant negative impact on the arable land area and abandoned farmland area of farmer households in the eastern and central and western regions,and has a positive impact on the transferred area of farmer households in the central and western regions,but it is not obvious for the eastern region.In conclusion,it is proposed to improve the supply of agricultural machinery socialization services and accelerate the reform of the household registration system.
