| 数字经济与海洋经济高质量发展互相影响。文章通过熵值-TOPSIS法构建我国数字经济和海洋经济高质量发展两个子系统共21个二级指标，运用耦合协调度模型得出我国2013—2019年11个沿海省（自治区、直辖市）的数字经济与海洋经济高质量发展的耦合协调水平以及耦合协调类型。研究发现：我国11个沿海省（自治区、直辖市）的数字经济发展呈现逐步上升的态势，海洋经济高质量发展趋势则比较稳定；2013—2019年多数沿海地区数字经济和海洋经济高质量发展两大系统的耦合度表现稳定，保持良好的动态关联关系；在数字经济与海洋经济高质量发展互动性增强的同时，两大系统的整体发展水平也有所提高。 |

| 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. |
