Abstract:The report of the 20th National Congress of the Communist Party of China emphasized the imperative to "develop the marine economy, protect the marine ecological environment, and accelerate the construction of a maritime powerhouse". To methodically review the research advancements and evolution of offshore wind power and the marine economy in China, this article selects 988 relevant papers published on China National Knowledge Infrastructure (CNKI) from 2013 to 2022 as research samples. By integrating bibliometric methods and knowledge map visualization technologies such as CiteSpace, this study investigates the distribution of research energy in offshore wind power technology and marine economy in terms of temporal and spatial distribution, knowledge base, research hotspots, and research frontiers. Furthermore, it deciphers the thematic overview of research on China's offshore wind power and marine economy through the evolution of research, hotspot content, and frontier trends. The findings indicate: (1) Theoretical research on the marine economy has undergone three stages: a "slow decrease phase— stable growth phase—rapid growth phase", and is currently in a fast development phase. (2) A stable group of publishing authors within the domain of marine economy theoretical research has yet to form, with higher education institutions being the primary publishing entities, predominantly concentrated in coastal areas such as Shandong, Tianjin, and Guangdong, thereby showcasing significant geographical traits. (3) Research hotspots focus on "wind power technology and marine economic development", "wind power technological innovation development", and "offshore wind power and marine industry development". (4) Future research hotspot choices will center on "wind power technology driving marine energy structure reform under the 'dual carbon' background", "wind power technology promoting the rapid development of marine engineering equipment manufacturing", "construction of wind power technology innovation platforms and exploration of blue finance", and "integrated development of wind power technology and marine ranching
