This study aimed to identify Research and Development (R&D) trends in the marine bioindustry in Korea and core technology elements and present implications for future research tasks. Bibliographic data on 4,875 Korean marine bio-related R&D projects conducted from 2002 to 2022 were collected through the National Science & Technology Information Service (NTIS). Keywords for each task in the collected bibliographic information were used for frequency and centrality analyses through network analysis. Results showed that Korean marine bio-related R&D studies have increased from 20 in 2002 to 542 in 2022, with an annual average of 17.9%. In the early 2000s, studies on keywords such as biotechnology, bioindustry, functional food, marine bioindustry, biosensors, and probiotics began, and as of 2022, blue carbon, climate change, carbon storage, living shoreline, tidal flats, and functional foods have emerged as central research topics. As a result of keyword network analysis to understand the overall research contents of the past 20 years, studies on microalgae, marine plants and microbes, reference genomes, functional genes, marine animals, and seaweeds accounted for the largest proportion. Based on the results of this study, we look forward to systematic research on the core technologies of the marine bioindustry by securing various types of big data.
