摘要
A universal bipartite model is proposed based on an energy supply-demand network. The analytical expression of SPL distribution of the node weight, the 鈥渟hifting coefficient鈥?and the scaling exponent are presented without edge weight growth by using the mean-field theory approach. The numerical results of SPL distribution of the node weight, the 鈥渟hifting coefficient鈥?and the scaling exponent with edge weight growth are also presented. The production鈥檚 SPL distribution of the US coal enterprizes from 1991 to 2009 is obtained from the empirical analysis. The numerical results obtained from the model are in good agreement with the empirical results.
