基于安全视角的农作物种子贸易效率分析OA

The DEA model was used to measure the trade efficiency of China's crop seeds from 2011 to 2021,and the seed industry se-curity level was evaluated by the efficiency value.The results showed that China's crop seed industry was generally in an insecure state with a tendency of further deterioration.The main reasons were as follows:the import volume of China's crop seeds had increased year by year,leading to a high degree of external dependence on seeds;meanwhile,there existed problems such as high concentration of import markets and weak trade competitiveness.Accordingly,some policy measures including promoting the merger and reorganiza-tion of seed enterprises,constructing a diversified seed import pattern,and enhancing the technological innovation capability of the seed industry were proposed,so as to safeguard the security of China's crop seed industry.
