The marine green fuel supply chain is a crucial component in the development of green ports.Focusing on the issue of cooperative contracts between port and green marine fuel supplier within the marine green fuel supply chain, firstly, a two-echelon marine green fuel supply chain optimization model consisting of a green marine fuel supplier and a port is constructed. Secondly, the changes in profits and decisions of green marine fuel supplier and port are compared under four scenarios: no contract, cost-sharing contract, revenue-sharing contract, and combined revenuesharing + cost-sharing contract. Finally, the propositions are validated using numerical simulation methods. The research findings show that, in terms of revenue, the combined profits of port and green marine fuel supplier under the combined revenue-sharing + cost-sharing contract exceed those under the revenue-sharing contract alone. Regarding the sale price of marine green fuel and bunkering service quality, these factors peak under the cost-sharing contract and reach their lowest under the revenue-sharing contract. An increase in the port's investment proportion in marine green fuel bunkering service quality leads to decreases in the bunkering volume, sale price, wholesale price, and bunkering service quality of marine green fuel under both the cost-sharing contract and the revenue-sharing + cost-sharing contract. Additionally, the higher proportion of revenue shared by the port with the green marine fuel supplier results in lower sale price, wholesale price, and bunkering service quality of green marine fuel under both the revenue-sharing contract and revenuesharing + cost-sharing contract.
