A large number of sample data are needed in the dynamic simulation analysis of port economic throughput difference in the marine environment. In the traditional dynamic simulation method, the distribution of sample data is unbalanced, which affects the reliability of the simulation results. Therefore, the dynamic simulation analysis of port economic throughput difference in the marine environment is proposed. This paper analyzes the influencing factors of port economic throughput, determines the appropriate influencing factors by calculating the correlation coefficient, constructs the port economic throughput difference model, takes the predicted value and the original number series obtained by the model as the input, uses the trend extrapolation method and the linear regression model to realize the dynamic simulation of port economic throughput difference. The experimental results show that: compared with the traditional dynamic simulation method, the sample data of the dynamic simulation method of port economic throughput difference under the designed marine environment is evenly distributed, and this method is suitable for practical projects.
