Abstract

Marine new infrastructure (MNI) is playing an increasingly important role in supporting marine fisheries, yet its impact on carbon mitigation remains insufficiently understood. The objective of this study was to develop and empirically test a conceptual framework linking MNI to low-carbon development in marine fisheries. We proposed a tripartite framework for MNI, comprising integration infrastructure, innovation infrastructure, and information infrastructure. Based on the measurement of marine fishery carbon emission efficiency (MFCEE) using a Super-EBM model across China's 11 coastal provinces from 2006 to 2021, the impact of MNI was evaluated. Results yielded three main findings: First, MNI significantly improved carbon efficiency, with integration infrastructure exhibiting the strongest effect, followed by innovation and information infrastructures; Second, the improvement in MFCEE was driven primarily by industrial structure optimization, aquaculture technology promotion, and production scale expansion; and Third, the effects of MNI were moderated by environmental regulation, for which command-and-control regulation showed a single-threshold effect, while market-based regulation presented a double-threshold effect. These regulatory thresholds helped explain regional disparities, with significant efficiency gains observed in the Northern and Southern Marine Economic Circles but efficiency losses in the Eastern Circle. Overall, this study provided a theoretical foundation for understanding MNI's role in low-carbon fisheries development and offered practical insights for spatial planning and regulatory design.
