The network domain which can pursue competitive advantages in business activities is characterized by exclusiveness. This exclusiveness is defined by companies not accepting anyone other than their own company or affiliated companies. The domain is also characterized by differentiation. Its sources of differentiation are subjective, tacit, or unsystematic knowledge which are constructed by the special relationship of the autonomous and voluntary members being linked for a long time. In this paper, it is referred to as network specialized knowledge (NSK). In addition, the primary network can be seen as the autonomous linking of equal term members. However, the network view discussed here is not a static view requiring each member's relationship to be fixed on equal terms in order to be recognized as a network, but is observed as a dynamic view. In the latter case, even if each member's relational base is originally authority, each member's relationship consciously excludes restrictions according to the aspect. If we consider the network from the structure aspect, we can classify two types of structure: decentralized and strategic. The former is that in which authorities are consciously transferred. This type of structure is not outside the existing framework of affiliated companies, related companies, and so on. The latter, however, is outside the existing framework. Even if companies are in competition, they are linked by the need to carry out high level strategies and by the need to create value. They are highly interdependent in regards to managerial resources on equal terms which are not restricted by authority or imbalanced dependence of managerial resources.
