农地确权、农机社会化服务选择与农户农业生产效率

Farmland Right Confirmation,Socialized Service Selection of Farm Machinery and FarmersAgricultural Production Efficiency

积极引导小农户卷入社会化分工经济,已经成为当前我国农业农村发展的重要导向。农户的农机社会化服务选择的产权含义始终没有引起学界重视,并且鲜有研究探讨农机社会化服务参与是否会提高确权农户农业生产效率。本文通过构建“农地确权—农机社会化服务参与—农业生产效率”的分析框架,根据2014年和2016年中国劳动力动态调查(China Labor⁃force Dynamic Survey,简称CLDS)的两期面板数据,采用PSM⁃DID模型,对农地确权对农户农机社会化服务与农户农业生产效率的净效应进行估计,并识别了农户农机社会化服务选择对农地确权效率决定的调节作用。研究结果显示:农地确权显著诱导农户参与农机社会化服务,但确权政策并未提高农业生产效率;农机社会化服务的参与将强化农地确权对农业生产效率的激励作用;农地经营规模差异引致农户对农机外包服务与自我服务的不同行为选择。

Actively guiding small farmers to participate in the socialized division of labor economy has become an important guide for the development of my country's agriculture and rural areas.The meaning of property rights of farmers’choices of agricultural machinery social services has never attracted the attention of academic circles,and there are few studies to explore whether participation in agricultural machinery socializd services will bring about improvements in the agricultural production efficiency of farmers with confirmed rights.This paper constructs the analytical framework of“Agricultural Land Right Confirmation—Agricultural Machinery Socialized Service Participation—Agricultural Production Efficiency”.Based on the two-phase panel data of the China Labor Force Dynamics Survey(CLDS)in 2014 and 2016,the PSM-DID model is used to estimate farmland confirmation.The net effect of the right to farm households'agricultural machinery socialized services and farm households'agricultural production efficiency,and to identify the moderating effect of farm households'agricultural machinery socialized service choices on the efficiency of farmland right confirmation.The research results show that:1)Farmland right confirmation significantly induces farmers to participate in agricultural machinery socialized services,but the right confirmation policy has not achieved a clear improvement in farmer's agricultural production efficiency;2)However,participation in agricultural machinery socialized services will strengthen the incentive effect of agricultural land right confirmation on agricultural production efficiency.Further evidence shows that the difference in the scale of farmland management has caused farmers to choose different behaviors for agricultural machinery outsourcing services and self-service.
