The results showed that environmental factors and random errors had significant effects on agricultural green production efficiency in the Yangtze River Economic Belt. The agricultural green production efficiency in the upper, middle and lower reaches of the Yangtze River economic belt had obvious spatial imbalance phenomenon. The difference of agricultural green production efficiency among provinces（cities） in the three regions of the Yangtze River Economic Belt showed a decreasing trend. Based on this, in order to further improve and spatially optimize the agricultural green production efficiency in the Yangtze River Economic Belt, the following suggestions were proposed, such as clarifying the regional environment and adapting to local conditions; grasping regional differences and implementing precise policies; breaking down the regional barrier and promoting coordinated development.

ESTAD model and geographic detectors were used to identify the spatial-temporal evolution characteristics of grain production efficiency in China as well as its influencing factors. The results showed that, from 2011 to 2019, China’s grain production efficiency was relatively high on the whole, showing a small dynamic decline trend, as well as obvious regional differences. The stability of local spatial structure and spatial dependence direction of grain production efficiency in China was strong. The stability of local spatial structure in eastern and western China was higher than that in central China, while the stability in central and western China was higher than that in eastern coastal China. The proportion of provinces （cities, autonomous regions） with synergistic growth of grain production efficiency and neighboring regions was 51.6%, mainly located in the south of the Yellow River, and the spatial pattern integration showed the characteristics of diversification and differentiation. Macroeconomic factors had the greatest impact on grain production efficiency, while policy support factors had the least impact. However, the interaction between policy support and other factors had a nonlinear enhancing effect.
