全球供应链企业的港口集聚模型与仿真

通过建立的二级单链全球供应链模型,运用NetLogo仿真平台,计算供应链企业迁移到港口集群所需要的供应链产量规模、供应链成本、供应链利润等指标.经过反复实验,发现港口作为全球供应链的重要节点有利于吸引供应链企业集聚,形成港口集群.在其他变量保持不变的前提下,通过进一步试验,明确影响全球供应链向港口集聚的主要因素.由于全球供应链中的节点企业是动态的,因此,基于Cournot模型和Stackelberg模型,运用博弈论方法,研究集群外供应商进入全球供应链所在港口集群的经济性.

Model and Simulation for Global Supply Chain Enterprises to Migrate to Port Cluster

A model of a single two-staged global supply chain is set up.The necessary production scale,costs,profits and other indicators are calculated for the global supply chain enterprises to migrate to port cluster based on NetLogo simulation platform.Repeated experiments indicates that the port as an important node in the global supply chain will attract supply chain enterprises to agglomerate to port cluster.And the main factors are analyzed by further tests under the premise that the other variables remain unchanged.Since enterprises in a global supply chain are dynamic,the economic issues for foreign suppliers to enter the global supply chain in the port cluster are discussed by game theory based on Cournot and Stackelberg model.
