Empirical Studies on the Dynamic Relationship between Port Logistics and Marine Economic Development in Fujian Province

The marine economy in coastal areas has a great role in promoting social development, and efficient port logistics serves the high-quality development of the marine economy. There is a dynamic relationship of dependence, restriction, and mutual promotion between port logistics and marine economy, which has regional differences. Based on panel vector autoregressive model (PVAR model), the relevant panel data of Fujian Province from 2000 to 2020 were analyzed by using the Granger causality test, impulse response, and variance decomposition methods. The interactive relationship between port logistics and marine economic development was discussed, and development suggestions were put forward. The results show that the development level of port logistics in Fujian Province is low, the logistics supply cannot meet the needs of marine economy, the effect of port logistics is not significant, and the support ability for the development of marine economy is insufficient. On the contrary, the development of marine economy promotes the development of port logistics industry and the economic growth of logistics related industries, and the strong market demand promotes the further improvement of logistics supply capacity. On the whole, the two-way feedback effect between the indicators of logistics industry and the development of marine economy is weak. In the future, it is necessary to further increase the layout of port logistics network system, strengthen the support ability of port logistics to the development of marine economy, and promote the scale and quality of port logistics by relying on marine economy.
