Abstract: Considering the decentralized technology of blockchain and the pricing decisions of members in the shipping supply chain, a port-carrier secondary shipping supply chain is constructed. The port establishes a private blockchain platform for information sharing, combined with the information sharing degree coefficient and the cost sharing ratio coefficient, constructs the pricing decision-making model in the traditional model and the blockchain technology-based model, and compares the optimal pricing strategies of the two models using Stackelberg game. The impact of different degrees of information sharing on private blockchain platforms on pricing and revenue is discussed. The results of the study found that after the port establishes a private blockchain platform, regardless of the degree of information sharing, it can always increase the carrier’s freight wholesale price and the port wholesale price. When the information is fully shared, the port has the greatest benefits, but at this time the carrier needs to bear all the platform construction costs, but its own revenue will be reduced and give up joining the private blockchain platform, in order to develop the carrier that can appropriately bear a certain proportion of the platform cost, under certain conditions can reach the optimal strategy.
