河南省农业绿色低碳发展效率评价研究OA

Promoting the green and low-carbon transformation of agriculture is a key pathway for achieving both national food security and ecological sustainability.Taking 18 prefecture-level cities in Henan Province as the research object,based on panel data from 2005 to 2024,this paper incorporated agricultural carbon emissions as an undesirable output into the analysis framework,and systematically evaluated the efficiency of agricultural green and low-carbon development in Henan Province over the past two decades by comprehensively using the global super-efficiency SBM model,Malmquist index and Tobit model to reveal its dynamic evolution characteristics and identify the key influencing factors.The results showed that:(1)The agricultural green and low-carbon development efficiency in Henan Province exhibited three distinct stages:fluctuating decline(2005-2010),slow recovery(2011-2019)and continuous improvement(2020-2024),and the overall pattern gradually shifted from low-level differentiation toward higher-level convergence.(2)The dynamic decomposition results indicated that the improvement in agricultural green and low-carbon development efficiency was primarily driven by technological progress,while the enhancement of comprehensive technical efficiency remained insufficient.Significant constraints still existed in technology diffusion,resource allocation and agricultural management.(3)The Tobit regression results revealed that agricultural production structure,land-scale operation level,effective irrigation area and fertilizer use efficiency significantly promoted agricultural green and low-carbon development efficiency at the 1%significance level.The disposable income of rural residents also exerted a significant positive effect at the 10%significance level.In contrast,agricultural fiscal support showed a significant negative effect at the 5%significance level due to mismatches in the allocation of financial resources.The level of agricultural mechanization was not significant.Policy implications:focus on optimizing agricultural production structure,promoting large-scale land operation,improving water-saving infrastructure,enhancing farmers'income support,adjusting the structure of agricultural financial investment and promoting the green transformation of agricultural machinery to achieve coordinated improvements in agricultural production efficiency and low-carbon transformation in Henan Province and other major grain-producing regions in China.
