Marine Engineering Research Reveals Insights into Fisheries' Economic Benefits

Researchers at the Ocean University of China have conducted a comprehensive study on the spatial coagglomeration of marine fisheries and its impact on economic benefits in coastal cities of China. The study, which employed machine learning algorithms and the Fairness, Similarity, and Goodness (FsQCA) method, aimed to provide decision-making support for optimizing marine fisheries layout and promoting high-quality fisheries' economic development.

Key Takeaways:

  • The study found that marine fisheries exhibit lower coagglomeration with marine engineering equipment manufacturing and marine shipbuilding than between the latter two due to differing development models and needs.
  • Urban coagglomeration indices vary by region, influenced by policies, resources, and competition, with northern cities having lower indices in 2015 but higher in 2022 compared to the south.
  • Coagglomeration is not pivotal for high fisheries' economic benefits; instead, non-coagglomeration emerged as a key factor in 2022.
  • The study suggests optimizing the allocation of resources, promoting regional coordinated development, strengthening policy support, and optimizing the spatial layout to promote high-quality coagglomeration of industry.
  • The research concluded that the study aims to provide decision-making support for optimizing marine fisheries layout, promoting high-quality fisheries' economic development, and building a modern marine industry system.

Statistics:

  • The study employed an enhanced Sinkhorn algorithm to optimize the Wasserstein distance, which calculated coagglomeration indices through hypothesis testing and Monte Carlo simulations.
  • The FsQCA method was used to assess whether coagglomeration enhances fisheries' economic benefits.
  • Urban coagglomeration indices varied by region, with northern cities having lower indices in 2015 (0.42) and higher in 2022 (0.61) compared to the south.
  • The study found that non-coagglomeration emerged as a key factor for high fisheries' economic benefits in 2022, with a coagglomeration index of 0.27.
