[Impact Mechanism of the Digital Economy on the Synergistic Effects of Pollution Reduction and Carbon Mitigation in Agriculture].

The impact mechanism of digital economy on agricultural pollution reduction and carbon mitigation synergy was investigated to inform coordinated environmental governance and climate response. Based on panel data from 30 Chinese provinces from 2013 to 2022, the spatiotemporal evolution characteristics were analyzed using the coupling coordination model and spatial econometric methods, with fixed-effects models and instrumental variable approaches employed for empirical verification. Key findings include: ① Both digital economy development and pollution-carbon synergy demonstrated an "eastern-high, western-low" regional disparity, though interprovincial gaps gradually narrowed. ② Digital economy significantly enhanced synergistic effects, with robustness confirmed through exogenous policy shocks and endogeneity controls. ③ Agricultural industrial structure upgrading and machinery technology advancement served as effective pathways. ④ Heterogeneity analysis revealed stronger effects in major grain-producing regions and economically developed provinces. These findings provide empirical evidence for digital economy-enabled agricultural green transition.
