Abstract: The effects of average degree on synchronization,gamesand information spreading are studied.The results show that increasing the average degree will enhance the synchronizability of networks,increase the cooperation rate in network,games and enlarge the spreading scale of information.Besides,it's found that the scale-free networks whose degree distribution is heterogeneous,show the synchronizability is strong when the coupling matrix is Laplacian and it is even stronger when the coupling matrix is normalized Laplacian.This study sheds light on the effects of average degree on the dynamical behavior of complexnetworks,which may be useful for the regulation of the corresponding dynamical behavior.

Key words: network, average degree, dynamic behavior
