摘要
为探究农业机械化服务对玉米生产效率的影响,利用面板随机前沿模型测算2004—2017年我国玉米主产区的玉米生产效率,并运用面板Tobit模型实证分析农业机械化服务对玉米生产效率的影响。研究结果表明:第一,我国玉米生产效率值整体上呈现增长趋势,玉米生产的效率损失从2004年的25.50%减少到2017年的23.40%。第二,农业机械化服务的供给水平和使用水平均对玉米生产效率具有正向影响,且分别通过10%和1%水平的显著性检验。据此提出加大对农业机械化服务组织的扶持力度、推进农业生产全程机械化服务和发展农业服务规模经营等对策建议。
In order to explore the impact of agricultural mechanization services on corn production efficiency,this study uses the panel stochastic frontier model to measure the corn production efficiency in China’s main corn producing regions from 2004 to 2017,and the panel Tobit model was used to analyze empirically the impact of agricultural mechanization services on corn production efficiency.The research results show that:the whole value of China’s corn production efficiency is increasing,and the efficiency loss of corn production has decreased from 25.50%in 2004 to 23.40%in 2017.In addition,the supply and use levels of agricultural mechanization services have a positive impact on the efficiency of corn production,and pass the significance test at 10%and 1%statistical level respectively.This research suggests that,it is helpful to strengthen the support to agricultural mechanization service organizations,promote the whole process mechanization services in agricultural production and develop the scale management of agricultural services.
