Research on the Impact of Marine New Quality Productive Forces on Marine Economic Resilience: A Case Study of 11 Coastal Provinces and Cities in China

The development of marine new quality productive forces and the enhancement of marine economic resilience are critical strategies for cultivating new drivers and advantages for high-quality and sustainable development in the marine sector. In order to deeply explore the relationship between these two constructs, this study selected panel data from 11 coastal provinces from 2007 to 2021 to construct an indicator system for MNQPFs and marine economic resilience, conducted scientific calculations and analysis, and, finally, used a two-way fixed effect model for empirical analysis and the instrumental variable method for robustness testing. The key findings are as follows: (1) The level of marine new quality productive forces (MNQPFs) in coastal areas demonstrates considerable spatial variability. The spatial distribution of MNQPF levels in the Bohai Sea and South China Sea regions is similar, whereas the levels in the Yellow Sea and East China Sea region demonstrate better balance. (2) A regional analysis of marine economic resilience indicates that the Bohai Sea region demonstrates a weak development trend and the South China Sea region demonstrates an unbalanced development trend, while the Yellow Sea and East China Sea region demonstrates a favorable development trend. (3) MNQPFs significantly improve marine economic resilience, including both its resistance and evolution abilities; the positive impact of marine new quality productive forces on the marine economic resilience’s recovery ability exhibits a time lag effect. (4) Heterogeneous results demonstrate that the positive impact of MNQPFs on marine economic resilience varies according to the level of marine economic development in different coastal areas, with a more significant promoting effect in less developed areas. Therefore, adaptively accelerating the development of marine new quality productive forces according to local conditions by effectively utilizing the unique resource endowments of each coastal area is essential for continuously strengthening marine economic resilience. This study can enrich research in the field of marine economics and provide references for marine economic development in coastal areas.
