Clustering coastal cities from incomplete data to sharpen marine tourism strategy
Classifying coastal tourism cities by tourist arrivals is essential for differentiated marine management, yet incomplete data often undermines the effort. This paper tackles that gap directly with a grey relational clustering method grounded in decision-theoretic rough sets. By separating perfect and missing data, it preserves groupings where records are complete while assigning uncertain cases to a boundary region rather than forcing them into clusters. The result: three distinct development modes among 11 Chinese coastal cities, offering practical, calibrated guidance for marine tourism strategy.
Digital Economy's Measured Impact on Marine Progress Across China's Coast
China's coastal provinces are discovering that digitalization and marine economic health rise together, though the relationship is more conditional than a simple win. Our new study, covering 11 regions from 2014 to 2023, confirms a positive baseline link between digital economy growth and high-quality marine development. Yet the association weakens under stricter statistical scrutiny, and green innovation intensity only matters past a threshold. This is exploratory evidence, not certainty.
Market Equilibrium Drives Efficient Sea Area Use Rights Allocation
Market equilibrium is not a abstraction; it is the quiet engine determining who gets access to the sea and at what cost. This study grounds that principle in the messy reality of marine resource allocation, showing that monopolies shrink both volume and economic efficiency. It is a measured, empirical reminder that how we structure markets shapes ocean stewardship. For readers tracking governance challenges, our related piece on dynamic port governance offers a complementary lens on resilience.
Measuring Efficiency: Untangling Natural Resource Productivity in Coastal China
China's eastern coastal region holds a natural resource productivity advantage 2.3 to 2.8 times that of inland provinces, driven by marine industrial agglomeration and port logistics. Our integrated SBM-DEA framework pinpoints exactly where efficiency gaps emerge, from regional technology disparities to intra-provincial losses. The three-echelon structure, with the Yangtze and Pearl River Deltas leading, offers a replicable tool for targeted policy. Related coverage on record port activity reflects this coastal momentum, yet the cross-provincial spillover remains untested.
Modeling China’s Coastal Growth: Integrating Economy, Innovation, and Ecology
Zhejiang's marine economy will not grow on scale alone. This study models it as a complex adaptive system, where innovation, port capacity, and ecological protection interact with delayed feedback. Notably, weaker innovation masks itself initially, but by 2030 it trims emerging-industry value added by 16.7%. Port shocks transmit directly to environmental investment, and ecological constraints shift from growth-supportive to limiting. Strong internal innovation buffers external shocks, adding RMB 35 billion to 2030 GOP. This is the integrated, systems-level thinking ocean management needs.
Measuring Marine Productivity: The Digital Economy’s Role in Coastal China
Coastal China's marine economy is increasingly shaped by digital forces, yet the relationship is far from linear. Our analysis of 11 provinces from 2011 to 2021 reveals an N-shaped curve: digital growth initially boosts marine new-quality productivity, then suppresses it, before a tentative recovery at higher indices. This pattern, with turning points at 0.198 and 0.618, underscores the need for calibrated policy. Regional scale and financial depth help; trade openness does not.
China’s Marine Enterprises: Dual Tech Paths Drive Productivity Gains
The right technology path is rarely a simple choice for marine enterprises, and new research from Chinese tax data confirms the stakes. Between 2016 and 2020, firms that paired independent R&D with external equipment purchases saw their total factor productivity climb, yet the gains are not infinite. Resource boundaries impose hard limits: as internal diversification or energy intensity crosses thresholds, returns shift downward. High-tech firms thrive on the dual path, while others wisely focus on equipment alone.
Low-Altitude Economy: A Catalyst for China’s Marine Economic Growth
China's marine economy is climbing, but the data shows it needs a new lift. From 2011 to 2023, we measured both marine quality and low-altitude economic activity, finding a clear upward yet regionally uneven trend. The low-altitude sector drives marine gains, though technology's push fades while green finance starts slow before accelerating. This isn't just about drones or data; it's about pairing innovation with policy. For deeper context on maritime shifts, see our piece on Gulf of Oman STS transfers.
