双碳目标下农民专业合作社效率测度研究——基于Super-SBM和Malmquist-Luenberger模型

Research on the efficiency measurement of farmers’professional cooperatives under the dual-carbon target:Based on Super-SBM and Malmquist-Luenberger model

考虑环境因素,将农民专业合作社碳排放量作为非期望产出,首先采用Super-SBM模型测量2014—2019年中国29个省(自治区、直辖市)农民专业合作社的综合技术效率、纯技术效率和规模效率,然后运用Global Malmquist-Luenberger指数模型测度了绿色全要素生产率、技术进步指数和技术效率变化指数。结果表明,农民专业合作社的综合技术效率水平较低,其主要是由纯技术效率偏低导致的;东部地区的纯技术效率和绿色全要素生产率均明显高于中西部地区;2014—2019年农民专业合作社的绿色全要素生产率呈增长趋势,其主要来源于技术效率的增长,而技术进步有轻微下降趋势。在上述结论的基础上,为了促进农民专业合作社绿色高质量发展,提高生产效率,提出了相应的政策建议。

Considering environmental factors,the carbon emissions of farmers’professional cooperatives were taken as the undesired output.Firstly,the Super-SBM model was used to measure the comprehensive technical efficiency,pure technical efficiency and scale efficiency of farmers’professional cooperatives in 29 provinces(autonomous regions and municipalities directly under the cen⁃tral government)in China from 2014 to 2019.Then the Global Malmquist-Luenberger index model was used to measure green total fac⁃tor productivity,technological progress index and technical efficiency change index.The results showed that the comprehensive techni⁃cal efficiency level of farmers’professional cooperatives was low,which was mainly caused by the low pure technical efficiency;the pure technical efficiency and green total factor productivity of the eastern region were significantly higher than those of the central and western regions;the green total factor productivity of farmers’professional cooperatives showed an increasing trend,which was mainly due to the increase of technical efficiency,while the technological progress had a slight downward trend.On the basis of the above con⁃clusions,the corresponding policy suggestions were put forward in order to promote the green and high-quality development of farmers’professional cooperatives and improve production efficiency.
