Based on a panel data from the National Rural Fixed Observation Points from 2009 to 2018，this paper uses the panel two-way fixed effect model，propensity score matching and treatment effect model to deal with the selection bias of farmers’ participation in training，and empirically analyzes the impact of training on farmers’ income.The results show that training contributes to the income growth of farmers，with the main source of income growth coming from the growth of agricultural income.The income growth effect of training is sustainable with a positive cumulative effect，but the impact decreases gradually over time.Training has little effect on the income disparity among farmers.The conclusions show that it is necessary to increase the intensity of agriculture-related training，adhere to the demand-oriented and farmer-centered approaches,arrange training in a graded and classified manner that suits the characteristics of different groups and meets the needs of farmers,increase the intensity of “high-quality farmer training”and“on-site training of agricultural technology extension”，tap the potential of non-agricultural training to increase income，and contribute to the rural revitalization and common prosperity.
