In order to deepen an understanding of the factors determining the boundary of regional innovation system, the prior studies on the function of networks were reviewed. This investigation derived a working hypothesis that a open network among the actors have an ambivalent effect on innovations. Then a policy program focused on the making networks were chosen as an object of analysis for evaluating the effects of network extensity on success of industrialization in the adopted projects. As a result supports the hypothesis, authors derived a policy implication that a proper openness of network is important to pursue the advantages of extension and cohesion in concurrently.
