The impact of marine industrial agglomeration on marine economic resilience—A case study of China's coastal areas

In the current complex domestic and international environment, marine economic resilience has become one of the basic guarantees for whether the marine economy can achieve high-quality development. At the same time, the development of the marine industry in coastal areas is undergoing rapid development and showing a trend of agglomeration, providing an unprecedented opportunity to increase marine economic resilience. Thus, the impact of marine industrial agglomeration on marine economic resilience deserves further investigation. This study takes 11 coastal provinces and cities in China as an example. First, marine economic resilience is divided into three subsystems: resistance ability, recovery ability, and evolution ability, and evaluated by several methods. Second, this study uses empirical methods to analyse the impact of marine industrial agglomeration on economic resilience and its influencing mechanism. The results show that: (1) Marine industrial agglomeration can significantly increase marine economic resilience. (2) Marine industrial agglomeration increases marine economic resilience through scale effects and spillover effects, and the impact of division of labor effects on marine economic resilience has a single threshold effect. (3) The impact of marine industrial agglomeration on marine economic resilience has significant spatial heterogeneity. Our study can enrich the research in this field and provide reference for the development of marine industry and marine economy in coastal areas.
