Accordingly, this paper evaluates intellectual capital from two periods. The first period is to evaluate value creation potential of intellectual capital; the aim is to see the dynamic change of intellectual capital quantity. The paper sums up static state quantity, combination efficiency and structural extent these three factors which influent on intellectual capital creation potential. Paper uses FA in the evaluation; the second period is to evaluate intellectual capital value using ability. The aim is to expose the using efficiency of intellectual capital. The research of this period is studied from internal enterprises and external ones. Internal factors come from enterprises bestir intellectual capital, external factors come from competition extent. On the base of theory analysis, the relationships which intellectual capital bestirs mode and competition extent do to intellectual capital value contribution come out. This period uses AHP to evaluate intellectual capital.
