Abstract: Coordinated promotion of agricultural carbon reduction and pollution reduction is the only way to achieve rural ecological revitalization. The deep integration of modern digital technology and agricultural economy has brought new opportunities for rural ecological revitalization. According to the idea of agricultural production emission reduction and carbon fixation, this paper verifies the logic of input factor reduction, agricultural waste resource utilization and production mode scale. Based on the panel data of 30 provinces from 2005 to 2022, quantifying synergies from the perspective of marginal emission reduction costs, the two-way fixed-effect model was used to verify the impact of digital technology on the synergistic benefits of agricultural pollution reduction and carbon reduction and its path mechanism. The results show that digital technology can help reduce the reduction of agricultural factor input and improve the efficiency of agricultural production, and then improve the synergistic benefit of pollution reduction and carbon reduction. The result was still valid after a series of robustness tests and endogeneity tests. Internal mechanism analysis results show that digital technology can reduce pesticides, fertilizers, agricultural film and irrigation water to achieve reductions, and improve agricultural production efficiency. The results of the external mechanism test show that digital technology is conducive to the transformation of rural energy structure and land circulation, that is, promoting the utilization of agricultural waste resources and agricultural production scale to improve the synergistic benefits of pollution reduction and carbon reduction. The results of heterogeneity analysis show that digital technology has a stronger effect on enhancing synergies in areas with high industrial integration and main grain sales.
