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.
