中国畜牧业绿色全要素生产率的区域差异与收敛性分析
Regional Differences and Convergence of Green Total Factor Productivity in China's Animal Husbandry
摘要
Abstract
Under the backdrop of the'dual carbon'strategy,it is necessary to analysis the regional differences in China's livestock industry's green total factor productivity and testing its convergence,which can provide empirical evidence for achieving regional green and coordinated development in the livestock industry.The panel statistical data from 31 provincial-level administrative units in China from 2006 to 2023 was selected.By constructing a Super-SBM model based on environmental negative outputs and combining it with the global-Malmquist-Luenberger(GML)index to measure the green total factor productivity(GTFP)of the livestock industry,the Dagum Gini coefficient was empirically analyzed,and its regional differentiation characteristics and formation mechanisms were further employed.Finally,the σ convergence and β convergence models were introduced to test its convergence patterns.The results indicated,during the study period,the average value of China's GTFP index for the livestock industry was 0.979,showing an overall negative growth trend.The key influencing factor was green technological progress,which exhibited significant regional non-equilibrium.The overall differences in GTFP in the livestock industry exhibited a fluctuating trend of first narrowing and then widening.In 2023,the overall Gini coefficient rose to a historical peak of 0.136,with inter-regional differences being the primary source of spatial disparities.The σ convergence of the GTFP of the livestock industry was not significant,but it exhibited absolute β convergence and conditional β convergence characteristics.Therefore,the government should focus on enhancing green technological progress,strengthening inter-provincial capital and technology flows,and promoting regional coordinated development.关键词
