The improved Lotka-Volterra model for the multi-goods of the multi-ports is proposed based on the competition of kinds of ecological populations in nature. Based on the analysis of the current throughput, annual average growth rate, potential throughput growth space, and the impacts of other port cargo throughput, the model establishes a competition coefficient matrix to determine the competitive cooperation model between different ports. The model is used to analyze the competition and cooperation relationship of different cargo types in four ports of Fujian. The results show that the model can reflect the mutual influence mechanism of competition and collaboration of multiple types of cargo in multiple ports, which can provide an effective and targeted basis for optimizing the cargo structure of ports and improving the competitive relationship of the ports.
