Abstract

This work employs the spatial econometric model to explore the potential relation between the condition of marine ecosystems and the rapid development of the digital economy (DE), focusing on the coastal area of China. While the environmental benefits of the DE are well studied regarding the land and atmospheric pollution, its influence on marine pollution (MP) remains underexplored, and this work aims to fill in this gap. By analyzing panel data from 42 coastal cities in China using a spatial Durbin model to examine both the direct and indirect impacts of the DE on MP, the results highlight the positive role that the DE plays in reducing MP, benefitting not only the local marine environments but also those of neighboring areas through non-negligible spatial spillover effects. In addition, we find a non-linear, inverted U-shaped relationship between the DE and MP. These results are further confirmed through extensive robustness tests. This work enriches the field of environmental economics by reporting the first empirical study on the marine benefits of the DE and offers policy recommendations to optimize digital technologies for marine environmental preservation.

探索数字经济对减轻海洋污染的影响：中国沿海空间计量经济学研究

本研究采用空间计量经济模型，以中国沿海地区为研究对象，探讨海洋生态系统状况与数字经济（DE）快速发展之间的潜在关系。虽然数字经济的环境效益在陆地和大气污染方面得到了充分研究，但其对海洋污染（MP）的影响仍未得到充分探索，本研究旨在填补这一空白。通过使用空间杜宾模型分析中国 42 个沿海城市的面板数据，研究可持续发展对海洋污染的直接和间接影响，结果凸显了可持续发展在减少海洋污染方面的积极作用，通过不可忽略的空间溢出效应，可持续发展不仅使当地海洋环境受益，也使邻近地区的海洋环境受益。此外，我们还发现豁免量与 MP 之间存在非线性的倒 U 型关系。这些结果通过广泛的稳健性测试得到了进一步证实。这项研究首次报告了 DE 的海洋效益实证研究，丰富了环境经济学领域，并为优化海洋环境保护的数字技术提供了政策建议。
