The 21st century is the century of the ocean, and the marine economy has become a new growth point of the national economy. the ocean has become the focus of world attention, which also intensifies the competition for reaching the heights of marine industry by major coastal countries. With the high-intensity development and use of marine resources, problems such as overfishing and environmental pollution have resulted in a series of depletions of renewable fishery resources, degradation of species, and even extinction, and the continuous reduction of nonrenewable resources such as marine crude oil. Based on the development status of China's marine industry, this article applies the improved particle swarm optimization algorithm to the study of the correlation between marine industrial clusters and the low-carbon level of the marine economy and then explores the transformation and upgrading path of China's marine industry from the perspective of the low-carbon economy.
