| 数字经济与海洋渔业的融合发展是海洋渔业高质量发展的重要动力。文章选择2012—2019年我国11个沿海地区的相关数据，实证研究数字经济对海洋渔业高质量发展的影响及其内在的作用机理和潜在的异质性。研究结果表明：从直接效应来看，数字经济对沿海地区海洋渔业高质量发展具有显著的正向推动作用，其影响强度由长三角地区、珠三角地区、黄渤海地区依次减弱；从中介效应来看，沿海地区和三大地区的产业结构升级在数字经济助推海洋渔业高质量发展的过程中都具有中介效应；就分地区样本来看，长三角地区、珠三角地区和黄渤海地区产业结构升级的中介效应以及产业结构升级对海洋渔业高质量发展的影响强度依次减弱。基于此，文章从大力发展数字经济、因地制定数字经济发展战略和促进产业结构升级等方面，为推动海洋渔业高质量发展提供政策建议。 |

| Abstract: |
| The integrated development of digital economy and marine fishery is an important driving force for the high-quality development of marine fishery. This paper selected relevant data from 11 coastal provinces in China from 2012 to 2019 to empirically study the impact of digital economy on the high-quality development of marine fisheries, as well as its internal mechanism and potential heterogeneity. The results showed that: from the direct effect, digital economy had played a significant positive role in promoting the high-quality development of marine fisheries in coastal areas, and its effect intensity decreased from the Yangtze River Delta region, the Pearl River Delta region and the Yellow Sea and Bohai Sea region. From the perspective of mediating effect, the upgrading of industrial structure had played a mediating effect on the high-quality development of marine fishery in the whole sample area of coastal provinces and the three major regions. From the perspective of regional samples, the mediating effect of industrial structure upgrading and the influence of industrial structure upgrading on the high-quality development of marine fishery in the Yangtze River Delta, Pearl River Delta and Yellow Sea and Bohai Sea had been successively weakened. Based on this, this paper provided policy suggestions for promoting the high-quality development of marine fishery from the aspects of vigorously developing digital economy, formulating digital economy development strategy according to local conditions, and promoting industrial transformation and upgrading. |
