Abstract

Abstract: Under global digital economy and marine power strategy, how to empower the development of marine economy through digital technologies has become a vital mission. This paper uses 2011 to 2021 panel data of China's 11 coastal provinces, and applies fixed effect model to study the transmitting path of digitalization on marine economy taking gross marine economic production as explained variables, digitalization extent as core explaining variable, industrial structural hierarchy coefficients and human capital stock as mediator variables. Infrastructures are vital to digitalization application. Household with internet stands for adjusting variable as infrastructures, whose function on digitalization is discussed via mutual item. Ocean pollution harness project amounts and storm disaster economic loss are used as environmental variables to further test the impact of external factors on marine economy. Digitalization as a key drive for new high-quality productivity plays a crucial role in high-quality development of marine economy through upgrading industrial structure and boosting human capital, and the latter is much more important than the former, suggesting talents determine the high-quality development of marine economy. Well-developed infrastructures play a positive adjusting role in digitalization's promoting high-quality development of marine economy. This paper presents suggestions on accelerating digitalization of traditional marine industries, on using digital technologies to drive the emerging industries of marine power, medicine and biological products, on intensifying ocean infrastructural constructions to decrease operating costs and increase producing efficiency of marine industries, on cultivating compound talents having marine knowledge and digital skills.

Key words: digitalization, infrastructures;marine economy, industrial upgrade, human capital

摘要： 在全球数字经济蓬勃发展和海洋强国战略深入推进的背景下，如何通过数字技术赋能海洋经济高质量发展已成为重要课题。基于2011—2021年中国11个沿海省份的面板数据，采用固定效应模型，以海洋经济生产总值为被解释变量，以数字化程度为核心解释变量，以产业结构层次系数和人力资本存量为中介变量，探讨数字化对海洋经济发展的传导路径；考虑到基础设施对数字化应用的重要性，采用互联网宽带接入用户数代表基础设施作为调节变量，通过交互项分析其对数字化影响效应的调节作用；同时引入海洋污染治理项目数量与风暴潮灾害经济损失等环境变量，进一步检验外部因素对海洋经济的影响。研究表明，数字化作为新质生产力的核心驱动因素，在推动海洋经济高质量发展中发挥着举足轻重的作用；数字化对海洋经济高质量发展的促进作用主要通过推进产业结构升级以及提升人力资本存量来实现，从长远来看，人力资本积累的重要性要远大于产业结构升级，高质量人才是海洋经济高质量发展的决定性因素；完善的基础设施对数字化促进海洋经济高质量发展具有正向的调节作用。基于上述研究结论，提出如下建议：加快传统海洋产业的数字化转型，利用数字技术推动海洋电力业、海洋药物和生物制品业等海洋新兴产业的发展；加强海洋领域基础设施建设，降低海洋产业的运营成本，提升海洋产业的生产效率；加强海洋领域高质量人才的培养，重点培养具备海洋领域专业知识和数字技术技能的复合型人才。
