Coupling and Coordination Analysis of High-quality Development of Chinese Digital Economy and Marine Economy

Abstract

The digital economy and the high-quality development of the marine economy influence each other. This paper uses the entropy-TOPSIS method to construct a total of 21 secondary indicators and uses the coupling coordination model to obtain the coupling coordination level and coupling coordination type of high-quality development of digital economy and marine economy of 11 coastal provinces and cities in China from 2013 to 2019. The study found that the development of the digital economy in 11 coastal provinces (autonomous regions and municipalities directly under the central government) in China showed a gradual upward trend, while the high-quality development trend of the marine economy was relatively stable. From 2013 to 2019, the coupling degree of the digital economy and high-quality marine development in most coastal areas was stable and maintained a good dynamic correlation. While the interaction between the high-quality development of the digital economy and the marine economy has been enhanced, the overall development level of the two systems has also been improved.
