In the big data era, increasing financial support for the marine economy and vigorously developing blue finance have a strong sense of urgency and historical mission, which need a larger macro vision and a more forward-looking strategic layout. Blue finance is related to China's economic and financial security. We must seize the development opportunities of blue finance in the new era and set up a systematic financial thinking of big countries. Only adopting the strategic thinking of innovation and development, can we support the marine economy in the big data era. [ABSTRACT FROM AUTHOR]
