Analysis of green total factor productivity of agriculture in Hunan province under the"dual carbon"goal
[Objective]Agricultural carbon emissions account for a high proportion of total carbon emissions.Reducing agricultural carbon emissions through green agricultural production and achieving the"dual carbon"goal is an important area that cannot be ignored,and it is also an inevitable requirement for the development of green agriculture.As a major agricultural province,Hunan province accurately identifies its obstacles by calculating the agricultural green total factor productivity and its core influencing factors,providing theoretical basis and decision-making reference for improving agricultural green total factor productivity,promoting agricultural green development,and achieving the"dual carbon"goal.[Method]The SBM-DDF index model was used to calculate the green total factor productivity and carbon emissions of agriculture in Hunan.Data from various cities and prefectures in Hunan from 2012 to 2022 were used for calculation,and their characteristics were analyzed from the perspective of temporal and spatial distribution;Establish a fixed effects model again,select the intensity of investment in production technology innovation,the intensity of adoption of green high-tech,the level of regional integration of primary,secondary,and tertiary development,and conduct regression research on the core factors affecting agricultural green total factor productivity,including the intensity of fertilizer and pesticide application,and the level of economic growth.[Result]The study found that under the"dual carbon"target,the annual green total factor productivity of agriculture in Hunan province showed a time series oscillation state,with uneven regional spatial distribution.The intensity of agricultural production technology innovation investment,the adoption of green high-tech,economic growth level,the intensity of fertilizer and pesticide application,and the intensity of regional integration of the first,second,and third industries were strongly correlated with agricultural green total factor productivity;From 2012 to 2022,the green total factor productivity of agriculture in Hunan province had been increasing year by year,with the progress of green high-tech being the main driving force,but the growth rate had shown a downward trend.[Conclusion]The implementation rate of the main technologies for green technology transformation and application in Hunan province is low;The innovation ability of agricultural green technology is not strong;The investment intensity of green production technology innovation and improvement is relatively low;The measures for the integration of regional development and the reduction of agricultural carbon emissions are not efficient.
