Research on the Evaluation of Agricultural Production Efficiency in China under the Background of Rural Revitalization:A Study Based on Three Stage DEA and Malmquist Index
Improving the efficiency of agricultural production is of great significance for increasing farmers'in-come,promoting sustainable agricultural development and promoting the strategy of rural revitalization.Using the three-stage DEA model to empirically analyze the agricultural production efficiency of 31 provinces(au-tonomous regions and municipalities)since the rural revitalization strategy was put forward,the study shows that environmental factors have little impact on the efficiency evaluation results of strong agricultural production provinces,and have a greater impact on less developed agricultural regions and regions that are developing green agriculture;from the perspective of the agricultural production efficiency measurement value in 2020,the difference in pure technical efficiency among the 31 provinces(autonomous regions and municipalities)is relatively small,and the difference in scale efficiency is large;from the change in the Malmquist index of agri-cultural production efficiency in 2017-2020,total factor productivity is in the state of rising and falling first,technical efficiency is relatively stable,and the growth of the technical progress index is more obvious.Based on the results of the analysis,policy recommendations for developing smart agriculture,deepening agricultural reform,and strengthening agricultural science and technology innovation are put forward.
