As an essential part of the supply chain, ports not only play a critical function in the national economic construction but also play a decisive role in disasters such as infectious diseases and natural disasters that negatively affect the lives of most sectors. In order to better evaluate the competitiveness of Chinese ports, this study constructs a competitiveness evaluation system for China’s top 5 ports. Based on the port competitiveness evaluation indexes, port competitiveness is divided into four aspects: infrastructure condition, port operation, economic environment, and port development potential. The entropy weight and TOPSIS method are utilized to evaluate the port’s competitiveness. The results show that the competitiveness of Shanghai port is much higher than that of other ports. It is suggested that each port should improve its own construction level and seek win-win results through dislocation development and collaborative cooperation.
