Research on the mechanism of low-altitude economy’s impact on marine economy quality and development countermeasures―threshold effect based on green finance

The intersection of emerging economic sectors and established maritime industries presents a compelling area for focused research, and this recent study analyzing the interplay between China’s low-altitude economy and its marine economy is a valuable contribution. The authors’ investigation, spanning from 2011 to 2023, utilizes sophisticated econometric modeling to not only quantify the impact of low-altitude technology on marine economic quality, but also to identify crucial moderating factors like technological innovation and green finance. This work builds on earlier explorations of sustainable maritime practices, such as the deployment of alternative fuels – evidenced by the First Container Ship To Run On Brazilian-Made Ethanol Sets Sail From Port Of Santos – demonstrating a broader shift toward more environmentally conscious operations within the sector. Furthermore, the need for robust regulatory frameworks to address global environmental challenges, particularly concerning marine plastic pollution, is underscored by studies like Comparative legal framework for marine plastic pollution control in China and Pakistan, highlighting the essential role of policy in fostering a sustainable marine ecosystem.

The findings regarding the positive, yet regionally heterogeneous, impact of the low-altitude economy on marine economic quality are particularly noteworthy. The observed non-linear effects of technological innovation and green finance provide a nuanced perspective, challenging simplistic assumptions about direct correlations. The initial promoting effect of technological innovation, followed by diminishing returns, suggests the importance of strategic investment and focused development rather than broad, undirected technological adoption. Similarly, the initial restraint imposed by green finance, eventually transitioning to a facilitating role, implies a learning curve and potential inefficiencies in the early stages of implementing sustainable financial practices within the marine sector. This highlights the need for calibrated policy interventions and adaptive strategies to maximize the benefits of both technological advancement and sustainable finance. The entropy method employed to measure both marine economic quality and low-altitude economic development provides a robust and data-driven approach to quantifying these complex phenomena, lending significant credibility to the conclusions drawn.

The study’s emphasis on coordinated top-level design speaks to the inherent interconnectedness of these economic sectors. Integrating low-altitude technologies—drones, aerial surveys, and unmanned vehicles—into marine operations presents a range of opportunities, from enhanced monitoring of ocean health and resource management to improved logistics and search-and-rescue capabilities. However, realizing this potential requires a holistic approach, considering regulatory frameworks, infrastructure development, and workforce training. The research underscores that maximizing the positive impact of the low-altitude economy on the marine sector isn’t simply about deploying new technologies; it’s about strategically aligning these technologies with broader economic and environmental goals. This echoes the global need for integrated data ecosystems, enabling real-time analysis of climate indicators and supporting informed decision-making for ocean stewardship, a core principle guiding our work at World Data Ocean.

Looking ahead, a crucial question arises: how can the lessons learned from China’s experience be adapted and applied to other maritime regions with varying levels of economic development and regulatory maturity? The identified threshold effects and the nuances of technological and financial interventions suggest that a ‘one-size-fits-all’ approach is unlikely to be effective. Further research should focus on identifying region-specific best practices and developing adaptable frameworks that can facilitate the sustainable integration of low-altitude technologies into diverse marine economies, ultimately contributing to a more resilient and productive global ocean.
