In recent years, environmental problems have become an important bottleneck restricting the sustainable development of Marine economy in China. CO2 is one of the main greenhouse gases which contributes to marine environmental problems. As CO2 emissions can transfer among industries, identifying the industries that release CO2 most and clarifying the carbon emission flows among marine industries are helpful for decision-makers to curb CO2 emissions of marine industries. This paper applies the network method to measure carbon emission flows. First, carbon transfer coefficient is calculated. Second, carbon transfer network of marine industry is constructed based on carbon transfer coefficient. Then the structure of marine industry carbon transfer network is analyzed. Finally, the method proposed in this paper is applied to the case of China and some suggestions for carbon reduction is put forward.
