摘要
基于不同的粮食功能区,分别运用超效率DEA模型和Malmquist指数法对2001—2019年中国三大粮食功能区的农业科技创新效率及其变化进行测度和比较。结果表明:2001—2019年3个区域的农业科技创新效率均呈现波动上升的趋势;各粮食功能区之间农业科技创新效率差异明显,由低到高依次为主产区、产销平衡区和主销区;粮食主产区规模效率优势明显,主销区技术进步优势较强,而产销平衡区各分解因素的波动幅度最大。最后,从宏观统筹和优化各粮食功能区农业科技创新要素配置、合理推进各粮食功能区农业科技创新、提高农业科技创新效率的视角提出了对策建议。
The agricultural science and technology innovation efficiency and its’changes in 3 grain functional areas in China from 2001 to 2019 are measured and compared by using the Super-efficiency DEA model and the Malmquist index method from the perspective of grain functional areas.The results show that the efficiency in different grain functional areas shows a fluctuating upward trend during the period of 2001 to 2019.The agricultural science and technology innovation efficiency among 3 grain functional areas from low to high in turn are main grain production area,grain production and selling balance area and main grain selling area.The main grain production area has scale efficiency advantage,main grain selling area has technology progress advantage,and balance area’s efficiency fluctuation range is highest.Finally,suggestions are given from the perspective of overall planning and optimizing the allocation of agricultural science and technology innovation resources in each grain functional area,and reasonably promoting the agricultural science and technology innovation and its efficiency in each functional area.
