Digital economy and economic resilience of marine fisheries in coastal cities: Based on the resource-based theory

The marine fisheries economy is an important component of marine economic development. It's meaningful to clarify the influence mechanisms of digital economy for marine ecological protection and sustainable development strategies. We construct the evaluation indicator system of the digital economy and the economic resilience of marine fisheries. This paper discovers that the digital economy can significantly improve the economic resilience of marine fisheries. The results remain robust and reliable after passing various robustness tests and endogeneity tests. We also find that the potential influence channels are industrial structure upgrading (industrial resources dimension), technological innovation (technological resources dimension), and human capital optimization (human resources dimension) based on the resource-based theory. Further, we show that the impact of digital economy on the economic resilience of marine fisheries has a “digital economy output” threshold effect and is moderated by the openness degree. We also discover that the facilitation effect of digital economy is more significant in the sample of the Southern Marine Economic Circle, large-sized and medium-sized cities. We explore the sustainability effect of digital economy. This paper refines the evaluation framework for the economic resilience of marine fisheries and extends the application of resource-based theory to the resilience domain. The research results provide important theoretical and practical insights to optimize the external environment for the economic development of marine fisheries.
