Abstract

Under the impetus of the new generation of technological revolution, digitalization offers new opportunities for the green development of the marine economy. Utilizing data from 11 coastal Chinese provinces and cities between 2011 and 2020, this paper constructs a comprehensive index system for the green development of the marine economy. Based on this, a fixed effects model is used to explore the impact of digitalization on the green development of the marine economy and its underlying mechanisms. The findings indicate that digitalization effectively promotes the green development of the marine economy, with this effect being more pronounced in regions bordering “the Belt and Road” initiative. Mechanism tests indicate that digitalization promotes the green development of the marine economy by raising the comprehensive development level of ports. When breaking down the components of port development, it is found that improving the port location quotient plays a more crucial role than port radiation intensity in how digitalization promotes the green development of the marine economy. Additionally, environmental regulation exerts a U-shaped moderating effect on the relationship between digitalization and the green development of the marine economy. Based on these findings, it is recommended to use digital technologies and data, expedite the development of marine big data platforms, integrate port resources, optimize port operations, and apply environmental regulation policies judiciously to promote efficient marine resource management and sustainable marine economic development.

数字化对海洋经济绿色发展的影响：来自中国沿海地区的证据

在新一代技术革命的推动下，数字化为海洋经济的绿色发展提供了新的机遇。本文利用2011 - 2020年中国沿海11个省市的数据，构建了海洋经济绿色发展的综合指标体系。在此基础上，采用固定效应模型探讨数字化对海洋经济绿色发展的影响及其潜在机制。研究结果表明，数字化有效促进了海洋经济的绿色发展，这一效应在“一带一路”沿线地区更为明显。机制试验表明，数字化通过提高港口综合开发水平，促进海洋经济绿色发展。通过对港口发展要素的分解发现，在数字化促进海洋经济绿色发展的过程中，港口区位商的提升比港口辐射强度的提升更为关键。此外，环境规制对数字化与海洋经济绿色发展之间的关系具有u型调节作用。在此基础上，建议利用数字技术和数据，加快海洋大数据平台建设，整合港口资源，优化港口运营，合理运用环境监管政策，促进海洋资源的高效管理和海洋经济的可持续发展。

期刊介绍： Frontiers in Marine Science publishes rigorously peer-reviewed research that advances our understanding of all aspects of the environment, biology, ecosystem functioning and human interactions with the oceans. Field Chief Editor Carlos M. Duarte at King Abdullah University of Science and Technology Thuwal is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, policy makers and the public worldwide. With the human population predicted to reach 9 billion people by 2050, it is clear that traditional land resources will not suffice to meet the demand for food or energy, required to support high-quality livelihoods. As a result, the oceans are emerging as a source of untapped assets, with new innovative industries, such as aquaculture, marine biotechnology, marine energy and deep-sea mining growing rapidly under a new era characterized by rapid growth of a blue, ocean-based economy. The sustainability of the blue economy is closely dependent on our knowledge about how to mitigate the impacts of the multiple pressures on the ocean ecosystem associated with the increased scale and diversification of industry operations in the ocean and global human pressures on the environment. Therefore, Frontiers in Marine Science particularly welcomes the communication of research outcomes addressing ocean-based solutions for the emerging challenges, including improved forecasting and observational capacities, understanding biodiversity and ecosystem problems, locally and globally, effective management strategies to maintain ocean health, and an improved capacity to sustainably derive resources from the oceans.
