Abstract: In order to provide theoretical and practical basis for the design and innovative practice of ecological agriculture training model in the future, and then provide policy inspiration for high-quality agricultural development, based on the relevant statistical data of 31 provinces, cities and autonomous regions in China from 2012 to 2021, the coupling and coordination relationship among the four factors of policy support, market competition, environmental awareness and training resources was analyzed. In this study, the coupled coordination degree model was used to construct the evaluation model of the coordination degree affecting the factor system of ecological agriculture training effect，and the spatiotemporal evolution characteristics of the coupling coordination among the four factors of policy support, market competition, environmental awareness and training resources were analyzed. On this basis, the key factors limiting the ecological agriculture training effect were identified through the barrier degree model, and the changing trends and constraints of the coupling coordination of the elements affecting the ecological agriculture training effect in China were explored. The results showed that the coupling coordination degree of the four factors in the 31 provinces from 2012 to 2021, cities and autonomous regions of China was in an overall rising trend from 0.478 to 0.565, with an increase of 36.61%, but the coordination level was still not high, and it was in a state of barely coordinated development for a long time. In terms of spatial distribution, the coupling coordination degree of the four factors showed significant positive correlation among provinces and autonomous regions. The obstacle degree of each factor in descending order was as follows: market competition, training resources, policy support, environmental awareness, and the main obstacle factor affecting the coupling and coordination of various factors was the amount of government subsidies in policy support, the number of agricultural colleges in market competition, the amount of organic fertilizer input in environmental awareness and the area of the training venue in the training resources.
