An extended clique degree distribution and its heterogeneity in cooperation-competition networks

► An extended clique degree distribution studied for bipartite graphs. ► A cooperation-competition network evolution model is proposed. ► Distribution of the clique degrees obeys a general function, P(q)∝(q+α)−γ. ► Define heterogeneity index and deduce its relationship with two other parameters. ► Empirical investigation results are in an agreement with the analytic conclusions.
