The reversible spreading processes with repeated infection widely exist in nature and human society,such as gonorrhea propagation and meme spreading.Identifying influential spreaders is an important issue in the reversible spreading dynamics on complex networks,which has been given much attention.Except for structural centrality,the nodes\' dynamical states play a significant role in their spreading influence in the reversible spreading processes.By integrating the number of outgoing edges and infection risks of node\'s neighbors into structural centrality,a new measure for identifying influential spreaders is articulated which considers the relative importance of structure and dynamics on node influence.The number of outgoing edges and infection risks of neighbors represent the positive effect of the local structural characteristic and the negative effect of the dynamical states of nodes in identifying influential spreaders,respectively.We find that an appropriate combination of these two characteristics can greatly improve the accuracy of the proposed measure in identifying the most influential spreaders.Notably,compared with the positive effect of the local structural characteristic,slightly weakening the negative effect of dynamical states of nodes can make the proposed measure play the best performance.Quantitatively understanding the relative importance of structure and dynamics on node influence provides a significant insight into identifying influential nodes in the reversible spreading processes.
