Evolution mechanism and improvement path of marine economy resilience in Bohai Rim Region

The marine economy resilience is one of the key attributes to measure the sustainable development of marine economy system. In this paper, the core and controlling influencing factors are systematically screened out. The cross-scale evolution mechanism of marine economy resilience of overall and inter-provincial in the Bohai Rim Region is explored by using the spatial econometric model based on the spatial effect level. Meanwhile, the feasible improvement path is proposed for each region considering the quantification utility levels of the influencing factors in each region. The results are as follows: (1) Marine industrial structure Ind and ocean-related employment Emp significantly enhance the marine economy resilience in the Bohai Rim Region, while financial development scale Fin significantly inhibits it; (2) The positive development trend of Liaoning’s marine economy resilience is mainly due to the promoting role of financial development scale Fin, marine industrial structure Ind and marine economy scale Sca; (3) The development of marine economy resilience in Tianjin-Hebei mainly depends on marine economy scale Sca and marine infrastructure Cap; (4) Financial development scale Fin, marine industrial structure Ind, marine economy scale Sca and marine infrastructure Cap have jointly promoted the rapid development of Shandong’s marine economy resilience. Therefore, the improvement path of the overall and inter-provincial marine economy resilience in the Bohai Rim Region is determined and proposed, which effectively promote the sustainable and stable development of its marine economy.
