摘要：
In this study, DEA Tobit model is used to carry out empirical analysis to study the regional differences in the input-output efficiency of agricultural ecological environment protection in various regions of China in 2018, and the influencing factors of the efficiency of agricultural ecological environment protection are analysed in depth. The results show that the input-output comprehensive efficiency of agricultural eco-environmental protection in North China, East China and South China is relatively high, indicating that the agricultural input structure in these areas can play a greater economic and social benefits; the comprehensive efficiency of northeast, central China, southwest and northwest areas is relatively low, indicating that the efficiency of agricultural eco-environmental protection in these areas is relatively low, and the input of eco-environmental protection is not living.
