Research on the resilience level of fishery economy in coastal areas of China

Abstract

Multiple risks such as environmental pollution, market risk, and extreme weather pose severe challenges to fishery production, fishermen 's lives and property, and the sustainable development of fishery. Improving the resilience of fishery economy is an inevitable requirement for coping with fishery production risks and achieving high-quality development of fishery economy. Therefore, based on the three dimensions of resistance and recovery ability, adaptation and adjustment ability, innovation and transformation ability, this study constructs a comprehensive index evaluation system of fishery economic resilience, and uses entropy method and Theil index method to measure the level of fishery economic resilience and regional differences in coastal areas of China from 2016 to 2023. The conclusions are as follows: (1) From 2016 to 2023, the level of fishery economic resilience in coastal areas of China showed a fluctuating growth trend of 'first decline and then rise', with an average value of 0.2566. (2) There are significant differences in the level of fishery resilience in different coastal areas. From 2016 to 2023, Shandong Province had the highest level of fishery economic resilience (0.5226), and Hainan Province had the lowest level of fishery economic resilience (0.0751). The eastern marine economic circle has the highest fishery economic resilience (0.2713), followed by the southern marine economic circle (0.2650), and the northern marine economic circle has the lowest fishery economic resilience (0.2371). (4) The regional differences in the level of fishery economic resilience in coastal areas of China mainly come from inter-group differences, with a contribution rate of 68.36 %. The difference in the level of fishery economic resilience between the three major marine economic circles has gradually become the most important factor affecting the difference in the level of fishery economic resilience in China.
