中文摘要:
      运用超越对数SFA模型测算1994—2016年中国15个小麦主产地区成本效率,继而构建空间杜宾计量模型考察农业机械化服务对小麦生产成本效率的直接影响与空间溢出效应。结果表明:中国小麦生产成本效率仍存在17.3%的损失;农业机械化服务对小麦成本效率具有正向显著的直接效应和空间溢出效应,即本区域农机化水平对其他区域小麦成本效率有显著的正向影响;从空间维度来看,农业机械化的空间溢出效应主要表现在经度相近地区之间,纬度相近地区之间并不显著;从时间维度看,2004年前后农业机械化的空间溢出效应具有明显差异,2004年之后空间溢出效应更加明显。据此提出农机补贴向农机服务组织倾斜,建设和推广农机信息平台以及作物种植沿经度布局的政策建议。
英文摘要:
      Applying the transcendental logarithmic Stochastic Frontier Analysis (SFA) model to estimates the cost efficiency of wheat production in 15 wheat producing provinces from 1994 to 2016,this paper then employs Spatial Durbin Model (SDM) to calculate the direct influence and spatial spillover effect of agricultural mechanization on the cost efficiency.The main findings include that the cost inefficiency is 17.3%,and the direct influence and spatial spillover effect on grain cost efficiency are noticeable,which means that interregional-service of agricultural mechanization has a positive effect on the grain cost efficiency of local region and the regions surrounding it.This testifies the reality that agricultural mechanization service is achieved among localities with different longitudes in China in terms of spatial distribution.From the perspective of time,the year 2004 is a divide,after which the spatial spillover was evidently manifested.As suggestion,it is proposed to give priority to agricultural machinery service organizations in allowance distribution,to construct and advocate the agricultural machinery information platform,and to distribute grain production along longitude.
