Abstract:: Research on agricultural eco-efficiency is of great significance to truly reflect the coordinated relationship between agricultural economic development and ecological environmental protection. In order to scientifically evaluate the agricultural development of the urban agglomeration in the middle reaches of the Yangtze River and provide a basis for its strategy formulation, we used the Super-SBM model with undesired output to measure the agricultural eco-efficiency based on the panel data of the cities in the middle reaches of the Yangtze River from 2000 to 2017, analyzed its time and space evolutionary patterns and spatial correlations, and used geographic detector models to detect the driving factors affecting agricultural eco-efficiency. The results show that:(1)the overall level of average agricultural eco-efficiency in the urban agglomerations in the middle reaches of the Yangtze River from 2000 to 2017 was relatively high, showing a trend of decrease-up-decrease; compared with Hubei Province, Hunan Province and Jiangxi Province had a large gap; the development of regional agricultural eco-efficiency was unbalanced, and regional differences had increased year by year;(2)from the perspective of spatial correlation, the global correlation of agricultural eco-efficiency in the urban agglomeration in the middle reaches of the Yangtze River presented the random-aggregation process; the phenomenon of agglomeration of agricultural eco-efficiency had gradually evolved over time, and the local spatial correlation was weak; there were different degrees of upward trend, and the spatial correlation gradually concentrated in the central area;(3)agricultural eco-efficiency was affected by multiple driving factors; in different years, some driving factors varied greatly; In different regions, the influence of driving factors on agricultural eco-efficiency showed certain regional difference. There is a lot of room for improvement in agricultural ecological efficiency in the urban agglomeration in the middle reaches of the Yangtze River, and the overall difference is gradually expanding. All regions should strengthen ties and take reasonable measures to promote the development of two-oriented agriculture.
