From the "four-chain integration" perspective, this study constructs an evaluation system of talent/innovation/industry/capital chains to measure marine new-quality productivity across 11 coastal provinces in China from 2011 to 2022. Using entropy weighting, kernel density estimation, and fuzzy-set Qualitative Comparative Analysis (fsQCA), we analyze spatiotemporal evolution and policy-driven pathways. Results indicate an overall upward trend with significant regional disparities. High-level regions exhibit multi-chain policy synergy, whereas medium-and low-level regions face constraints from insufficient talent and capital support. Policy focus has shifted from industry-led to innovation-capital synergy. The study offers empirical support for differentiated policy design to promote coordinated regional development of marine new-quality productivity.
