In contrast to the economic systems literature of the "cold war" period, contemporary authors cannot regard the existence and consistency of economic systems as self-evident. The difficulties that ex-communist economies of the East European and CIS countries had to face revealed the necessity of a reorientation in the understanding of the systems' formation and transformation. This paper argues firstly the advantage of an evolutionary perspective of the systems' transformation. The evolutionary perspective provides researchers with a dynamic and non-deterministic view that contains interdependent relationship between behaviors of micro agents and macro conditions. Further, this paper proposes to integrate the concept of "governance" into the evolutionary perspective. The development of information (knowledge) that deals with overall degree of "governance" and its mechanism signify the peculiarity of the evolution in the human or social level. In the last part, this paper classifies several types of the "governance" in the public domain and suggests the task of the "governance" of the evolutionary path of the changing economies.
