Yu, H.; Wang, Y., and Li, D., 2023. Using the AHP-entropy weight method to study regional marine economy resilience in China. Journal of Coastal Research, 39(5), 960–969. Charlotte (North Carolina), ISSN 0749-0208.

Marine economy has become an important part of China's national economy, but it is facing many constraints and disturbances from within and outside the region. Marine economy resilience can reflect to what extent the region will overcome these problems and achieve sustainable development. Nevertheless, evaluating marine economy resilience is a difficult task requiring considerable effort that is missing in the literature. This paper constructed the evaluation index system from the four dimensions of resistance, recovery, reorganization, and renewal and comprehensively used the analytic hierarchy process and entropy method to make a quantitative assessment of marine economy resilience in 11 coastal regions of China. Based on this, the paper then explored the spatial and temporal evolution of regional marine economy resilience. The evaluation results reveal that the overall level of China's marine economy resilience from 2006 to 2016 shows a fluctuating and rising trend. The resistance ability is generally in an upward fluctuating trend, the recovery ability fluctuates little but has no significant improvement, the reorganization ability also shows a fluctuating and rising trend, and the renewal ability has the largest increase in the four dimensions. This paper puts forward three suggestions for the coastal province governments to improve regional marine economy resilience in terms of technological innovation, green development, and coordinated opening up.
