摘要
在"双碳"目标导向下,研究省域农业碳排放效率对利用农村减碳空间,促进低碳农业转型具有重要战略意义.利用非期望产出SBM-GML模型测算除港澳台、西藏之外中国大陆30个省、市、自治区2010-2022年农业碳排放量和农业碳吸收量,进而测算各省市农业碳排放效率,分析其静态和动态演变特征,并构建空间计量模型研究其空间收敛性.研究表明,我国农业碳排放效率整体呈现上升趋势,北部沿海地区农业碳排放效率最高,长江中游地区农业碳排放效率最低,各省存在较大差异,大部分省份效率仍处于中下水平,存在较大减碳潜力;技术进步有助于农业碳排放效率提高,而农业技术效率限制动态农业碳排放效率进一步上升;各省农业碳排放效率存在空间收敛特征,低效率省市向高效率省市"追赶",农业机械总动力、产业结构对其收敛性存在显著影响.基于此,各省应该实施差异化农业碳减排策略,加大农业技术进步,调整产业结构,从而推进低碳农业转型,加快农业生态文明建设.
Abstract
Guided by the"double carbon"goals,the study of provincial agricultural carbon emission efficiency has important strategic significance for utilizing rural carbon reduction space and promoting low-carbon agricultural transformation.The non-expected output SBM-GML model is adopted to measure the amounts of agricultural carbon emission and agricultural carbon uptake in 30 provinces,municipalities,and autonomous regions in Chinese mainland,excluding Hong Kong,Macao,Taiwan,and Tibet.Then,the agricultural carbon emission efficiency of each province and municipality is measured,their static and dynamic evolution characteristics are analyzed,and a spatial econometric model is constructed to explore their spatial convergence.The findings are as follows:China's agricultural carbon emission efficiency shows an overall upward trend,and the northern coastal areas have the highest agricultural carbon emission efficiency,the middle reaches of the Yangtze River have the lowest agricultural carbon emission efficiency,and with large disparities among provinces,the majority of provinces are still at the lower and middle levels of efficiency,with great carbon reduction potential;technological progress contributes to the rise of agricultural carbon emission efficiency,while agricultural technical efficiency limits the dynamic agricultural carbon emission efficiency to further increase;the agricultural carbon emission efficiency of each province features spatial convergence,and provinces and municipalities with low efficiencies are catching up with those of the high efficiency,and the total power of agricultural machinery and industrial structure have significant impacts on spatial convergence.According to the research,the municipalities,and autonomous regions should employ differentiated agricultural carbon emission reduction strategies,enhance agricultural technological progress,adjust industrial structure,so as to promote the transformation of low-carbon agriculture and accelerate the construction of agricultural ecological civilization.
