Abstract

Drawing on panel data from 14 coastal cities in Guangdong Province for the period 2014–2023, this study employs a dynamic panel model to examine the causal relationships among marine science and technology innovation, industrial structure optimization, and high-quality development of the marine economy. The empirical findings reveal three pivotal conclusions: (1) Marine science and technology Innovation significantly promotes the high-quality development of the marine economy, with a markedly stronger effect in the Pearl River Delta region than in eastern and western Guangdong; (2) Industrial structure optimization serves as a partial mediating channel through which technological innovation drives high-quality development, accounting for 21.64% of the total effect; (3) The mediating role of industrial structure optimization has strengthened over time, indicating an increasingly robust transmission mechanism whereby technological progress fosters high-quality development via structural upgrading. In light of this, we propose recommendations including strengthening technological innovation, optimizing the industrial structure, deepening regional cooperation, and improving institutional frameworks, to offer insights for the high-quality development of Guangdong's marine economy.
