Citation Network

A citation network is the directed graph formed by scholarly publications as nodes and citations as edges. It is the structural substrate of the academic career system, and it operates with preferential attachment dynamics: well-cited papers attract more citations, producing a heavy-tailed degree distribution that concentrates visibility in a small number of hub papers.

The citation network is not merely a map of intellectual influence. It is an incentive structure. Researchers optimize for network position because the metrics derived from the network — citation counts, h-index, impact factors — determine hiring, promotion, and funding. The network thus becomes a self-referential system in which the goal is not to produce knowledge but to produce citations, and the distinction between the two is systematically blurred.
