Analysis of Agricultural Green Total Factor Productivity and Its Influencing Factors Based on SBM-GML Index
In this study,the global SBM-GML index was used to measure and decompose the agricultural green efficiency and green total factor productivity of 31 provinces in China from 2011 to 2019,and the influencing factors were analyzed with the Tobit model.The results showed that the growth of green total factor production efficiency in China's agriculture was relatively slow,in which technical efficiency was the key factor promoting the growth,while technological progress played restricting role to certain extent.From the perspective of the 31 provinces in China,14 provinces achieved agricultural green efficiency in 2019.The growth rate of agricultural green total factor productivity of Henan,Jiangxi and Guangdong were the top three in the country.Economic development level,industrial structure and fiscal expenditure had positive effects on the improvement of agricultural green total factor productivity,while human capital structure and environmental regulation had negative effects.Natural disasters had negative effects on agricultural green total factor productivity in the whole country,central and western China,and positive effects in eastern China.
