The study aims to measure the impact of the blue economy on economic growth rates in Libya by understanding and analyzing how marine resources are utilized and their role in increasing economic growth. It also identifies the challenges and opportunities associated with the blue economy and finds solutions that combine economic growth with environmental conservation. The study relied on an econometric approach using the Autoregressive Distributed Lag (ARDL) model to measure the impact of blue economy variables on GDP, relying on data from the Central Bank of Libya. The study results revealed a co-integration relationship between the variables in the model, and that the independent variables explain 98% of the variance in economic growth. The study also demonstrated the enormous potential for the blue economy in Libya to achieve sustainable economic growth, as it can contribute to creating new job opportunities, improving livelihoods, and diversifying the economy away from dependence on oil. The study recommended the development of a comprehensive blue economy strategy, improving marine infrastructure and addressing challenges related to illegal fishing and marine pollution, developing qualified personnel, and providing the necessary funding for blue economy projects in Libya................
