Driven by the rural revitalization strategy, the development of digital economy has brought a new development path for agricultural green total factor productivity. Based on the panel data of 29 provinces and regions in China from 2014 to 2022, this paper systematically discusses the internal mechanism and implementation path of digital economy and green agricultural total factor productivity. The entropy method and super-efficiency SBM model were used to measure China's digital economy level and agricultural green TFP. and a bidirectional fixed effect model was constructed to explore the impact of digital economy on agricultural green TFP. The results show that (1) both China's digital economy and agricultural green TFP present an increasing trend, and the development of digital economy has a significant positive promoting effect on the improvement of agricultural green TFP and this conclusion is consistent in multiple robustness tests. (2) Through the intermediary effect, it is found that digital economy has an effect on agricultural green total factor productivity through labor transfer effect and agricultural industry agglomeration; (3) Heterogeneity analysis shows that digital economy has regional differences in agricultural green total factor productivity, and there is a phenomenon of increasing level from west to central to east; (4) The threshold effect of expansion analysis shows that regional economic development level plays a positive role in improving agricultural green TFP. is a region with higher economic development level, has a correspondingly higher agricultural green TFP. Based on this, it is proposed that a mechanism for agricultural green innovation and promotion should be established, the concept of ecological and green development should be adhered to, and the agriculture should develop in the direction of high digitalization, green ecology and intelligent innovation, so as to promote the high-quality development of China's agriculture.
