【摘要】 本文选取2020-2022年吉林省15个主栽玉米品种，运用DEA-SBM模型进行生产效率分析。实证研究表明，吉林省玉米品种生产实践中表现较好的是翔玉998、良玉99、翔玉211、郑单958，表现优良的玉米品种中吉林省本土品种所占比例不高，玉米品种市场竞争力较弱，种业发展水平相对滞后。对于非有效玉米品种而言，单纯提高某种生产要素并不能有效改变生产效率，需要全要素合理有效配置才能实现整体效率的提升。因此，需要提高现代育种技术水平、发展高效种植技术、培育本土现代种业集团，最终提升吉林省种业竞争力。更多还原

【Abstract】 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 necessary 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 ultimately enhance the competitiveness of Jilin Province’s seed industry.更多还原
