According to the character of local evolving mechanism in real network, we propose a new local-clustered network evolving model (LC model). Theoretical analysis and numerical simulations show that the LC model obeys a power-law degree distribution with an exponential cut-off, and its cluster coefficient is much bigger than the local-world model (LW model) proposed by Li and Chen and is more, close to real network. We simulate the performance of LC model against random errors and malice attacks, and discover that LC model is more fragile under attacks because of its large cluster coefficient.
