Abstract: This paper uses BBC model and Malmquist index to estimate the 2015 and 2018 eco-sustainable efficiencies and efficiency dynamic change indexes of Jilin’s 23 major crop counties, analyzes their status from technology, scale, resource element allocation, and studies the global auto-correlation, and discusses the spatial pattern and dynamic changes of agricultural eco-sustainability with issues disclosed and approaches presented. Jilin’s agricultural eco-sustainability of its major crop areas is at a general level, but higher in a few counties/cities, largely variable among the 23 counties. Counties with efficiency less than 1 are, high to low, Da’an(0.941), Dongliao(0.934), Panshi(0.926), Dunhua(0.86), Dongfeng(0.77), Antu(0.76), Yanji(0.74), Yongji(0.71), Helong(0.67), most in Liaoyuan, Jilin and Yanbian. Their comprehensive efficiencies are independent and related each other, showing to some extent spatial concentration and good eco-sustainability, reaching up to the optimal in Changchun, eastern Siping eastern Songyuan, improved in Sulan, Shuangliao, Qian’an, Tongyu, Da’an and Dongfeng in 2018, but decreased in Yanbian, Yongji, Panshi and Dongliao. Inappropriate inputs in agricultural eco-sustainability exist in some counties that should be reduced in Yongji, Dunhua and Dongfeng, but increased in Fuyu, Qianguo, Changling, Qian’an, Zhaonan, Tongyu, Da’an and Dongliao.
