摘　　要：Agricultural eco-efficiency is an important indicator to measure the sustainable development and high-quality development of agriculture.Based on the agricultural input-output data of 37 districts(counties)in Chongqing from 2004 to 2019,this paper uses the static SBM model and the DDF-BML index method to calculate the agricultural eco-efficiency of each district and county in Chongqing and conduct a comparative analysis.The comprehensive analysis of static and dynamic calculation results shows that the agricultural eco-efficiency of Chongqing is low,the agricultural input-output efficiency of various districts and counties is insufficient,and slack variables are common,so the ability of agricultural sustainable development still needs to be improved.The main sources of agricultural eco-efficiency are the progress of agricultural green technology and the efficiency of agricultural green technology.However,as far as the actual situation of Chongqing is concerned,the efficiency of agricultural green technology shows a downward trend,which has an inhibitory effect on the improvement of agricultural eco-efficiency.Therefore,in the process of agricultural ecological development in the future,Chongqing will focus on improving the efficiency of agricultural green technology as a starting point,implement agricultural technology innovation and promotion,improve the level of farmers’science and technology and culture,and achieve"technology to the countryside,demonstration to households,and application to the country."At the same time,it is necessary to further improve the construction of agricultural and rural infrastructure,and promote the"outward migration"of frontier technologies in agricultural production to radiate agricultural development in surrounding districts and counties.
