Analysis of Agricultural Production Efficiency in Anhui Province Based on Three-stage DEA Model
Based on the input residents'proenvizonmental behaviors were studied output data of agricultural production in Anhui Province in 2021,the evaluation index system of agricultural pro-duction efficiency was constructed,and the three-stage DEA model was used to measure the agri-cultural production efficiency of Anhui Province in 2021.The per capita disposable income of rural residents,expenditure on agriculture,forestry and water affairs and urbanization rate were selected as environmental variables.The change trend of comprehensive technical efficiency,pure technical efficiency and scale efficiency of Anhui city before and after adjustment is discussed.The results show that:After eliminating the influence of environmental factors and random disturbances,the comprehensive technical efficiency and scale efficiency of Anhui Province have improved,and the pure technical efficiency has decreased by 0.1%.Although the overall agricultural production effi-ciency has not reached the high efficiency level,it has improved compared with before adjustment.The low level of pure technical efficiency after adjustment in most cities reflects the lack of profes-sional management mode and advanced technical level of agricultural production.From the per-spective of environmental factors,the increase of per capita disposable income of rural residents and the increase of expenditure on agriculture,forestry and water affairs have a significant positive effect on agricultural production efficiency,while the urbanization rate has become a negative fac-tor for agricultural production efficiency.
