Analysis on Technical Efficiency Difference of Maize Farmers——Evidence from Stochastic Frontier Analysis and Farmers'Micro Data
This paper is based on 372 sets of survey data from four provinces in China:Heilongjiang,Liaoning,Hebei,and Shandong.The propensity score matching method and stochastic frontier model are used to obtain a pro-duction efficiency model for maize farmers.Based on a maximum likelihood detection,production efficiency models for different sizes of maize farmers are determined,and the production efficiency model and level of farmers are esti-mated separately.The results indicate that the efficiency of large-scale farmers before matching is higher than that of small-scale farmers,while the results after matching are opposite.Based on the research conclusions,this paper provides reference and suggestions for improving the efficiency levels of farmers who are reluctant or unwilling to change the area of maize cultivation.
