考虑不同节点行为要素特征的供应链演化规律研究

为研究供应链的实际演化规律，以复杂网络理论中的多局域世界模型为原型，提出了一种包含局域性节点与全局性节点且反映多种供应链行为要素的供应链网络演化模型。该模型验证了在自然演化情况下，现实供应链网络均具有一定的幂律性；通过算例对比分析说明，该模型相较现有文献中的演化网络能更好地模拟现实的供应链网络。研究表明，在供应链的自然演化过程中，网络的连通性和传输效率不断增强，由于新节点企业多与较大规模的企业合作而忽略了其他企业，其节点间紧密程度降低；企业与供应链网络的紧密度逐步发展到一定的程度将趋于稳定，大规模企业的发展速度先增加后放缓，各规模节点发展速度在中后期保持稳定。

Study on evolution law of supply chain considering characteristics of behavior factors of different nodes

In order to study the actual evolution law of supply chain, based on the multi-local world model in complex network theory, this paper constructed a multi-local-world model which included supply chain network evolution of local node and the global node. Through mean-field theory and analysis of simulation experiment, this paper verified the power law of the model. Simulation experiment data show that the connectivity and transmission efficiency of the network continue to increase in the natural evolution of the supply chain. As new node enterprises cooperate with larger enterprises and neglect other enterprises, the tightness between nodes is reduced. The degree of closeness of enterprises and supply chain networks will gradually stabilize to a certain extent, and the development speed of large-scale enterprises will increase first and then slow down; the development speed of each scale node will remain stable in the middle and late period.
