As one of the most important entrance of system thinking, these progress will influence science and society deeply. This paper has discussed two new theories emerged these years, so-called small world network and scale free network. Their basic concepts and implication have been discussed. Based on our lab's research this paper also provides some theoretical view point on the network research. Some open topics and direction have been briefly mentioned also.
