Spatial differentiation and driving mechanism of the marine economic resilience in China

Abstract

Enhancing the marine economic resilience is an inevitable requirement for the marine economy to achieve high-quality development. Based on the measurement results of the marine economic resilience in China's coastal provinces from 2005 to 2020, its spatial differentiation is elaborated, and its driving mechanism is analyzed using the random forest model. The research conclusions are as follows. (1) From the perspective of spatial pattern differentiation, the overall marine economic resilience is improving, high-value areas are evolved from the early “north-south” point distribution towards blocky and contiguous distribution. (2) From the perspective of spatial density differentiation, the overall density curve changes from a "steep peak" to a "gentle peak" during the overall rightward shift, and the regional differences in the marine economic resilience have expanded. (3) From the perspective of spatial differentiation decomposition, the intensified differentiation of the east-north and east-south sea circles is the driving force for the expansion of regional differences in the marine economic resilience. (4) The main reason for the above in the evolution process is the differences in primary driving factors. Factors such as industrial scale, green inhibition intensity, and government finance have a certain inhibitory effect on the spatial differentiation of marine economic resilience. Based on the research findings, the theoretical and practical value of this paper were explored.
