Research on Node Relationship Management in Strategic Networks Based on Niche Theory

From the systemic point of view, strategic network is a complex system. Based on niche theory in ecology, this paper proposes the concept of niche of enterprise node in strategic network, and tries to research into the measuring model for the breadth and overlap of node niche in strategic network This research shows that strategic network node not only has to choose appropriate niche, but also make right adjustment and optimization of the niche according to their goals and environmental change. At last , it promotes the evolution of strategic networks.
