Abstract: The self-similarity of complex networks has broad practical backgrounds. The reason and the course of self-similarity networks are formed and these three statistics characters of complex networks are discussed and analyzed in detail in this paper; besides, the concept of self-similarity groups is defined. This paper proposes that different local networks can be covered with different shortest path to reveal the self-similarity of complex networks. Both theoretical analysis and simulation results are the evolution and characters more exactly for many complex networks of the real world.

Key words: complex networks, free-scale, self-similarity, volume dimension
