Abstract: Improving total factor productivity of agricultural is an important path to comprehensively promote rural vitalization and move faster to build up China’s strength in agriculture. Based on the quasi-experimental research data of the industrial poverty alleviation pilot project in the Wumeng and Liupan mountain area, this paper uses the Differences-in-Differences model (DID) to address potential endogeneity and the panel data of 807 farmers in 7 countries across 3 provinces to analyze the effect of industrial poverty alleviation projects on total factor productivity of agricultural. The study found that industrial poverty alleviation cooperatives can significantly improve farmers’ total factor productivity of agriculture. Robustness analysis and placebo test further strengthen the reliability of empirical analysis results. The heterogeneity analysis showed that the industrial poverty alleviation cooperative project had a greater impact on the agricultural total factor productivity of the sample groups of large cultivated farmland area, less agricultural labor, high age of household head and non-registered households. Mechanism analysis shows that industrial poverty alleviation cooperatives can improve farmers’ total factor productivity by providing technical training. It was further found that industrial poverty alleviation cooperatives can improve the agricultural income of farmers by improving the total factor productivity of agriculture. Based on the above conclusions, we should continue to support industrial cooperatives in the rural revitalization stage to drive the development of farmers, pay attention to the differential impact of industrial cooperatives on different farmers, and improve the supply capacity of industrial cooperatives for technical training and technical training, so as to continuously improve farmers' total factor productivity of agriculture and increase farmers’ income.
