摘要
通过构造一个简化的能源供需网络演化模型,从基本上刻画出中国目前的能源供需现状。在该模型中,供应节点的度分布反映了能源供应企业的市场占有份额。数值模拟结果表明,能源供需网络中供应节点的顶点度近似服从幂率分布,这说明能源供需网络具有无标度性。最后,给出了一些关于能源供需策略的建议。
An evolution model of energy resource supply--demand network was constructed to de scribe the actual energy resource demand--supply in China. The degree of energy resource supplies enterprise can represent its market share. The simulation results indicate that the vertex degree of supplies enterprise approximately obeys the power-law. It is proved that this network has the characteristics of scale-free. Some suggestions of energy resources supply-demand strategy are given.
