Analysis of Production Efficiency of Corn Varieties in Jilin Province Using the DEA-SBM Model
Fifteen main planted corn varieties in Jilin Province in 2020-2022 are selected and analyzed for the production efficiency using the DEA-SBM model.The empirical study shows that Xiangyu998,Liangyu 99,Xiangyu211,and Zhengdan958 perform well in production practices.However,the proportion of high-performing corn varieties among local varieties in Jilin Province is low,indicating weak market competitiveness and a relatively lagging of the seed industry development.For non-efficient corn varieties,merely improving individual production factors does not effectively enhance production efficiency,a reasonable and effective allocation of all factors is nec-essary to achieve the overall efficiency of the enhancement.Therefore,it is crucial to improve the level of modern breeding technology,develop efficient planting techniques,and cultivate local modern seed industry groups to ulti-mately enhance the competitiveness of Jilin Province's seed industry.
