- 摘要:
- 大豆产业的振兴发展是推动乡村振兴的重要抓手,为全面分析主产区大豆的生产效率,基于提高生产效率角度,提出促进大豆产业发展,助力乡村振兴提出合理的对策建议。选取2012—2021年我国10个大豆主产区的面板数据,运用DEA-BCC模型和Malmquist 指数测算主产区大豆生产效率,从静态和动态两个角度对比分析主产区大豆生产效率。结果表明:在2013年、2017年和2021年,主产区大豆综合技术效率均值分别为0.950,0.975和0.974,整体水平较高,但均未达到有效状态,仍有一定提升空间;2021年非DEA有效大豆主产区存在不同程度的投入冗余和产出不足;2012—2021年主产区大豆的全要素生产率均值为0.988,处于负增长状态,技术进步是推动主产区大豆全要素生产率提高的关键因素。综上,提出以下建议:强化大豆产业的科技支撑和资源配置能力,推动技术进步,提高大豆纯技术效率;合理扩大种植规模,优化种植结构,完善农业基础设施,提高大豆规模效率;健全灾害防范体系,降低大豆种植灾害风险损失,提高豆农灾害处理能力。
