Abstract: The "twin-wheel drive" of finance and technology profoundly affects regional production activities. The impact of synergistic linkage of different green development factors on regional economic resilience still needs further exploration. Based on panel data of 30 provincial-level regions in China from 2011 to 2023, this paper employs two-way fixed effects models, mechanism tests, moderation models, and spatial Durbin models to examine the impact of the synergistic development of green finance and technological innovation on regional economic resilience. The results show that: (1) The overall level of synergistic development between green finance and technological innovation in China is relatively low but has increased steadily over time, displaying a spatial gradient characterized by higher levels in the eastern region and lower levels in the western region. (2) The synergistic development of green finance and technological innovation contributes to the enhancement of regional economic resilience, mainly through two channels: demand-side consumption structure upgrading and supply-side technology market development, while environmental regulation exerts a negative moderating effect on this relationship. (3) The positive impact of the synergistic development of green finance and technological innovation on regional economic resilience is more pronounced during 2016–2023, in western regions, in areas with low green development levels, and in resource-dependent regions. (4) The synergistic development of green finance and technological innovation exhibits a positive spatial association effect in promoting regional economic resilience, and its spatial role may operate through economic linkages and distance decay. This article provides empirical evidence for enhancing regional economic resilience from the perspective of synergy between green capital allocation and technology supply and transformation.
