The economic value realization of blue carbon is crucial for promoting ocean sustainable development and addressing global climate change. In today's blue carbon development context, the synergy between green finance and technological innovation is increasingly prominent, serving as a key channel to activate the latent value of blue carbon resources. This study examines the coupling of green finance and technological innovation in nine Chinese coastal provinces from 2005 to 2021 by constructing an indicator system and a coupling coordination model, and analyzes how they jointly enhance marine carbon sink value. Research findings reveal that the interaction between green finance and technological innovation exhibits a U-shaped effect on realizing marine carbon sink value. Specifically, the U-shaped influence of the coupling coordination degree between green finance and technological innovation on marine carbon sink value is mediated through marine carbon sink efficiency and marine aquaculture structure. Moreover, this influence exhibits distinct regional heterogeneity. Based on these findings, this paper proposes policy recommendations to formulate differentiated green finance policies, innovate marine carbon sink financial instruments, and promote corporate technological synergy and management optimization. These measures aim to enhance the synergistic effects between green finance and technological innovation, thereby further unlocking the potential for marine carbon sequestration.
