| 摘要: |
| 21 世纪被誉为“海洋的世纪”，而海洋产业链面临的韧性挑战尤为突出。随着数字经济的迅猛发展，数字化基础设施的建设对提升海洋产业链韧性至关重要。基于 2005—2020 年中国投入产出数据，文章实证分析了“数字化硬件设施”“数字化软件服务”“数字化基础设施”对海洋产业链韧性的影响效应。研究结果表明，3 种因素均显著促进了海洋产业链韧性的提升。进一步的分析结果表明，2011 年以前，数字化基础设施和数字化软件服务对海洋产业链韧性的影响为负，2011 年后转为正向，而数字化硬件设施在 2005—2020 年始终具有正向效应。基于这一发现，文章建议从以下 3 个方面着手提升海洋产业链的韧性：第一，引入先进设备，升级数字化硬件设施；第二，加大对海洋产业数字化软件服务的投入，提升海洋产业数字化软件服务的质量和水平；第三，推动海 洋产业实现硬件与软件的高效结合，促进两者的协同发展，不断增强海洋产业链的韧性。 |

| Abstract: |
| The 21st century is widely regarded as the“Century of the Ocean”，and the marine industrial chain faces particularly prominent resilience challenges．With the rapid development of the digital economy，the construction of digital infrastructure has become critical for enhancing marine industrial chain resilience．Using Chinese input-output data from 2005 to 2020，this study empirically examines the effects of digital hardware facilities，digital software services，and digital infrastructure on marine industrial chain resilience．The results show that all three factors significantly promote the improvement of marine industrial chain resilience．Further analysis indicates that before 2011，digital infrastructure and digital software services had negative effects on marine industrial chain resilience，but their effects turned positive after 2011，whereas digital hardware facilities maintained a consistently positive effect throughout the period from 2005 to 2020．Based on these findings， the paper recommends enhancing marine industrial chain resilience through three strategies：first，introducing advanced equipment and upgrading digital infrastructure；second，increasing investment in digital software services to improve their quality；and third，promoting the efficient integration and coordinated development of hardware and software to continuously strengthen marine industrial chain resilience. |
