Research on Agricultural Production Efficiency in Linyi City Based on DEA-Malmquist Model
The input-output panel data of agricultural production factors in various districts and counties of Linyi from 2013 to 2021 were selected,and agricultural production efficiency in Linyi was measured and evaluated based on the input-oriented DEA-BCC model.The Malmquist index was used to dynamically analyze the agricultural production efficiency in Linyi,and the interannual variation trend of efficiency was analyzed from the dynamic point of view.The results show that there are significant differences in agricultural production efficiency among different regions of Linyi.The overall level is low,and most regions are in a trend of increasing returns to scale.The driving force for the improvement of agricultural total factor productivity in Linyi mainly comes from technological progress,and the average annual growth rate is on the rise.it is proposed to optimize the input of production factors,improve the scale efficiency;strengthen the research and popularization of agricultural technology,promote the progress of agricultural technology,increase fiscal expenditure and improve agricultural production efficiency.
