To explore the possibility of implementing the hub-and-spoke collusion mode in the port and shipping system in the context of new hub-and-spoke collusion,the paper builds a hub-and-spoke collusion model among a port and two shipping companies,and analyzes the equilibrium strategy of the port and shipping companies with capacity constraint under hub-and-spoke collusion.It is found as follows:before hub-and-spoke collusion,the tacit collusion between shipping companies can cause loss to port profit;through hub-and-spoke collusion,the port and shipping companies respectively reduce their service prices and freight rates,and under the premise of ensuring that shipping company profits remain unchanged,the port profit improves and the total profit of the port and shipping system increases.From a long-term perspective,the hub-and-spoke collusion is the optimal strategy for ports and shipping companies.The stability of hub-and-spoke collusion among ports and shipping companies is greater than that of tacit collusion between shipping companies.The research results can provide decision-making reference for preventing and regulating the new collusion mode in the shipping industry.
