The high-quality development of the aquaculture industry is of great significance for ensuring food security and promoting regional economies, and improving the technological level is an important driving force for breaking through industry bottlenecks and enhancing core competitiveness. This study aims to deeply explore the multi-dimensional driving mechanism and enhancement path of aquaculture competitiveness. Based on the theoretical framework of Porter’s Diamond Model, it uses panel data from 30 provinces in the “China Fishery Statistical Yearbook” from 2014 to 2025 to empirically test the impact of technological level, resource endowment, policy support, related industries, and market scale on industry competitiveness using a partial least squares structural equation model. The empirical results show that technological level and resource endowment not only directly drive the development of supporting industries and market expansion, but also enhance overall efficiency through mediation transmission mechanisms. Policy support can stimulate market demand. Related industries play an important role in enhancing competitiveness.
