Evaluation and Evolution Characteristics of Agricultural Green Total Factor Productivity in Jiangsu Province
Based on the agricultural input-output data,this paper uses SBM super-efficiency model to calculate the agricultural green total fac-tor productivity of 64 counties in Jiangsu Province from 2011 to 2020,and analyses the source of changes in productivity and the temporal evo-lution of productivity through GML index method.Research has found that the agricultural green total factor productivity in the counties of Jian-gsu Province have achieved good growth totally,and the growth performance in south of Jiangsu is better than that in middle and north of Jiang-su.The main driving force for the growth of agricultural green total factor productivity comes from the progress of agricultural technology,while the overall efficiency of agricultural technology shows a downward trend.Although the overall growth trend of agricultural green total factor pro-ductivity is relatively balanced,the driving force of its growth shows obvious regional differences.Finally,based on the measured analytical re-sults,countermeasures are proposed to enhance the level of green agricultural development in terms of strengthening the application of agricul-tural technology,coordinating regional agricultural development,and formulating differentiated development policies.
