Depending on this thought, and according to the relating principles of the science about system, we carried through the initial creating thought about innovation , which have already been discussed frequently by the experts. The innovative elements are the most radical factors in the innovative system, which are also the basal ingredients that creating the system. Complexity and uncertainty are the intrinsic characters of the factors, which endow the innovative activities with insignificance of unfolding; the mechanism of non-linearity makes these elements to produce all kinds of affiliations, subsequent the mechanism of conformity coordinates as well as colligates and blends and advances on the basis of non-linearity, thereby the innovative behaviors achieve the leap in the affects and functions, so the systematic affects and functions forms, the innovative behaviors construct the practical framework in the landscape and portrait orientation; in fact, the process of the systematism of innovation is human beings social behaving, so, the evolvement of the systematism of innovation possesses the essential natures of opening and arrangement as well as self-organizing and rushing, which are the principles of evolvement.
