Influence of the Reform of the Collection and Storage System on the Technical Efficiency of Maize
Based on the panel data of 10 major maize producing provinces from 2001 to 2020,this paper con-structs a stochastic frontier model to measure the technical efficiency of maize,and then analyzes the influence of the reform of maize collection and storage system on its technical efficiency by using a fixed effect model.The re-sults showed that since 2001,the average technical efficiency in both the implementation and non-implementation areas of maize policy reform had increased year by year,but the overall technical efficiency in the reform area was higher and the growth rate in the non-reform area was faster.In addition,it is found that the temporary purchase and storage policy is compared with the"price-subsidy separation"policy,showing that the latter has a greater impact.This means that compared with the temporary purchase and storage policy,the"price-subsidy separation"policy is more effective in improving the technical efficiency of maize production.At the same time,appropriate reduction of agricultural labor,strengthening agricultural infrastructure and ensuring effective irrigation will also help improve the technical efficiency of maize.
