基于三阶段超效率SBM-GML的中国畜牧业全要素碳生产率演变特征及影响因素
Evolutionary characteristics and influencing factors of total factor carbon productivity of animal husbandry in China based on the three-stage super-efficiency SBM-GML model
摘要
Abstract
To accurately evaluate the low-carbon production performance of animal husbandry and reveal its spatial-temporal differentiation characteristics and influencing factors,based on the three-stage super-efficiency SBM and GML index,the total factor carbon productivity in animal husbandry and its influencing factors were determined and analyzed in 31 provinces in China from 2001 to 2020(The data do not include those of Hong Kong,Macao and Taiwan regions.The same below).A panel regression model was used to reveal further the bias and effect of technological progress,technical efficiency,and scale efficiency changes on improving input-output in animal husbandry.The results showed that:1)China's low-carbon production efficiency in animal husbandry achieved an average annual growth rate of 3.33%,but the overall level was not high(0.695)and the regional differences were obvious,showing a pattern of"South China>Huang-Huai-Hai>Northeast>Qinghai-Tibet>Middle-lower Yangtze River>Northwest and along the Great Wall>Southwest";2)The growth of total factor carbon productivity in China's animal husbandry industry is mainly due to technological progress and economies of scale,and the low efficiency of labor input and carbon emission is the main reason for the deviation of total factor carbon productivity from the production frontier;3)The current technological progress in animal husbandry tends to promote intensive utilization of factors and has no significant impact on carbon emission efficiency,while the technical efficiency has a significant positive impact on the improvement of carbon emission efficiency in animal husbandry;4)Economic development,government support,animal husbandry industry structure and scientific and technological innovation all have significant effects on total factor carbon productivity of animal husbandry.关键词
