Quantitative analysis of the impact of port economic development on maritime logistics and supply chain efficiency

Entering the new century, the role of the ocean as a growth of regional economic development has become more prominent. This study focuses on the quantitative analysis of the impact of port economic development on the efficiency of maritime logistics and supply chain, using the synergy model to analyze multiple ordinal covariates of the port economy and naval logistics supply chain subsystems. And find out the optimal synergy matching degree between port economies and maritime logistics supply chain sub-systems among multiple ordinal covariates. Finally, X port is taken as a research case to demonstrate the coordination relationship between port economic development and the efficiency of the maritime logistics supply chain. The results show that from 2012 to 2023, the synergy value between the economy and the marine logistics supply chain of Port X shows a growing trend, and the level of synergistic development between the two is also increasing year by year. It shows that the synergy model constructed by the research can reflect the degree of synergistic development between the port’s economic development and the maritime logistics supply chain in a more comprehensive way and has general applicability. Meanwhile, the results of the study can provide a theoretical basis for the formulation of port logistics policy and regional economic development planning in the coastal economic zone.
