Impact of Port Trade on Regional Economic Development Based on System Dynamics

Under the trend of economic globalization, industrial exchanges with technology and capital as carriers are emerging worldwide. The port trade has played an increasingly important role in the national economy, and its functions have been further expanded from a traditional transportation node to an international trade center. This paper aims to study the impact of port trade on the regional economy. To this end, it designs a system dynamics model of "port trade-regional economy based on the system dynamics simulation, the overall framework of the economic system, and the basic cause and effect diagram of the system, and then performs related analysis through practical cases. Finally, the targeted suggestions were proposed. The study found that the coordinated and sustainable development of port trade and the regional economy requires a scientific and rational development approach, and the simultaneous development of port trade and the national economy. The research findings provide a theoretical basis for analyzing and evaluating the relationship between port trade and regional economic development.
