Knowledge creation in networks: a comparison between firm-network and network of firms

Network is often considered as a support of knowledge creation. We consider that two main forms of networks can be identified in the economy: horizontal and vertical. We propose to compare these networks according to the question of knowledge creation. The aim of this article is then to demonstrate mathematically the hypothesis that a decentralized network is more efficient in terms of knowledge creation. This hypothesis supposes that interactions between firms promote collective learning and collective knowledge and increase performances. We propose to describe, in terms of mathematical metaphors, the two forms of network in order to compare afterwards their dynamical evolution. JEL Codes: D85, L2, O3
