Abstract: From the aspects of navigation service, reservation navigation, green and low carbon, the service level index system of inland navigation hub under the reservation mode of 6 first-level indicators and 22 second-level indicators is constructed. Secondly, the game comprehensive weighting method is used to combine the qualitative weights and quantitative weights determined by the interval two-tuple linguistic method and the CRITIC method respectively. Then, based on the matter-element extension theory, the service level evaluation model of inland navigation hub under the reservation mode is constructed. Finally, taking the Three Gorges navigation hub of the Yangtze River as an example, the empirical analysis is carried out to verify the scientificity and feasibility of the model. The research conclusion has a good reference value for improving the service level of inland navigation hub.
