利用辽宁省352份玉米种植户的实地调查数据,采用超越对数随机前沿生产函数模型,测度玉米种植户生产技术效率,分析农户采纳农业生产性服务对玉米生产技术效率的影响,并分析服务主体异质性的影响差异.研究表明,被调查区域玉米种植户技术效率分布主要集中在0.6~0.8和0.8~1.0,均值为0.71;采纳农业生产性服务对玉米生产技术效率具有正向促进作用.从组织化服务主体和从同一服务主体获取农业生产性服务,均对玉米生产技术效率具有正向促进作用.根据研究结论,提出从加大农业生产性服务推广力度、强化农业生产性服务主体建设和引导通过多种形式整合土地资源等方面提高玉米生产技术效率.
Effect of Agricultural Productive Service Adoption on Corn Production Technology Efficiency
This study used field survey data from 352 corn farm households in Liaoning Province to assess the technical efficiency of corn production.The transclog-stochastic frontier production function model was employed to analyze the impact of farm households'adoption of agricultural productive services on corn production efficiency and to examine the differences in impact due to service subject heterogeneity.The results showed that the distribu-tion of technical efficiency of corn growers in the surveyed area was mainly concentrated within the ranges of 0.6-0.8 and 0.8-1.0,with an average value of 0.71.The adoption of agricultural productive services had a positive effect on the technical efficiency of corn production.Both obtaining agricultural productive services from organized service subjects and from the same service subjects had a positive effect on the technical efficiency of corn production.Ac-cording to the conclusion,to improve the technical efficiency of corn production,it was necessary to increase the pro-motion of agricultural productive services,strengthen the construction of agricultural productive services and guide the integration of land resources in various forms.
