Measurement and Regional Difference Analysis of Agricultural Green Innovation Efficiency in China
Scientific evaluation of the efficiency level of agricultural green innovation,measurement of regional heterogeneity of agricultural green innovation development,and clarification of the key path of agricultural green innovation development are of great significance for promoting agricultural modernization in China.The three-stage Super-SBM model was used to estimate the agricultural green innovation efficiency of each province in China from 2009 to 2020,and the Dagum Gini coefficient and convergence model were used to study the regional differences and spatiotemporal evolution characteristics of agricultural green innovation efficiency in China.The conclusions are as follows:There are significant inter-provincial differences and regional imbalances in agricultural green innovation efficiency,and the gap widens slightly with the passage of time.The efficiency of agricultural green innovation is mainly negatively affected by environmental factors.Waste of resources and excessive discharge of agricultural pollutants are the main reasons for the low efficiency of agricultural green innovation in some provinces.The gap of efficiency level of agricultural green innovation tends to expand and there is significant conditional β convergence.
