Spatiotemporal dynamic assessment and obstacle analysis of economic resilience in China’s marine fisheries

Abstract

Abstract With global climate change and increased overfishing, the sustainable development of marine fisheries economies faces many challenges. This study evaluates the resilience of the marine fishery system in China’s coastal areas in a systematic, scientific, and comprehensive manner by establishing the ANP-EWM-TOPSIS comprehensive evaluation system, analyzing the temporal and spatial changes in the economic resilience of marine fisheries, and exploring the main obstacles affecting resilience. The results show that the fishery system in Chinese marine regions demonstrates significant resilience both temporally and spatially. From the analysis of temporal and spatial variations, the economic resilience of marine fisheries in Fujian and Shandong provinces is relatively high and shows a clear upward trend, while the changes in economic resilience of marine fisheries in Tianjin and Shanghai are not significant. Regarding obstacle factors, the dimensions of resistance and innovation exhibit relatively high levels of obstacles. The findings of this study are of great significance for enhancing the economic resilience of marine fisheries in coastal regions worldwide.
