农地确权方式与农户农业服务外包行为——来自PSM-DID准实验的证据

农地确权对农户农业服务外包的影响在学界引起了关注,但仍未见文献关注不同地权界定方式对农业服务外包的影响。利用广东省阳山县提供的“常规确权”和“整合确权”独特准实验场景,研究不同确权方式对农业服务外包的异质性影响,运用PSM-DID模型的计量结果表明:相较于常规确权,整合确权促进农户农业服务外包行为更加显著,提高幅度达到30.41%;但整合确权对不同环节、不同种植规模农户的服务外包行为的影响不一致,主要提升了小规模农户的整地环节外包程度。本研究表明,农地确权方式选择对农业服务规模经营发展具有不同的影响效应,有必要分离出不同确权方式影响的细致差异。

Methods of Land Titling and Agricultural Service Outsourcing:Evidence from PSM-DID Model Based on Quasi-experimental Data

The impact of land titling on farmers’agricultural service outsourcing has begun to attract attention in the academic sector,but there is still no literature on whether there are differences in the impact of various methods of land titling on agricultural service outsourcing.Based on a quasi-experiment of“general land titling”and“land consolidation titling”that appeared simultaneously in Yangshan County,Guangdong Province,this article distinguishes the differences in the impact of various methods of land titling and their heterogeneous impact on agricultural service outsourcing.The results of PSM-DID estimation show that,compared with the general land titling,the land consolidation titling significantly promotes the farmer’s agricultural service outsourcing,leading to a 30.41%increase in the farmer’s agricultural service outsourcing.However,the land consolidation titling has a significant heterogeneous impact on the outsourcing services links and farmers’rice planting scales,mainly to improve small-scale farmers’ploughing link.These findings reveal that the choice of land titling methods has different effects on agricultural service scale management,and it is necessary to distinguish the different microscopic impacts between multiple methods of land titling.
