Abstract To further study the details of the topological characteristics of Chinese airline network, this work explored the new topological features of China Aviation Multi-layer Network (CAMN) based on complex network theory. We defined each airline as a layer in network and established a multi-layer network by simulating the evolution of network characteristic parameters in the layer-by-layer process. The results indicate that overlapping degree value of CAMN obeys a power-law distribution and five airports with highest overlapping value are uniformly distributed among airlines. Meanwhile, CAMN presents the characteristics of scale-free networks in aggregation, but characteristics of the small world network can only be obviously observed in aggregation of multi-layer networks. Further, the cooperation of large-scale airlines makes network more efficient. The phenomenon of small world in Chinese aviation aggregation network is mainly caused by the corresponding layer of large and medium-sized airlines. The transportation efficiency of large and medium-sized airline networks is higher than that of low-cost airlines, but the homogeneity is poorer.
