摘要 在BA模型中引入技术相似程度这一变量,分析无标度网络的形成过程及其结构特点对FDI技术溢出效应的影响。仿真结果表明,新模型生成的网络具有无标度性。当节点之间的相对于外商的技术相似程度差异较大时,节点度分布变得相对比较均匀。网络中少数连接数较大的节点以及相对于外商高的技术相似程度对FDI技术溢出效应有重要影响,而网络的小世界特性以及节点间技术相似程度的差异,对于大节点企业所产生的影响起到一定的纠偏和调节作用。 Sale-free network is prevailing in the actual world. A new model is proposed which introduce a factor technology proximity into the BA model to find out how the forming processes of the scale-free network influence the effect of FDI spillover. We find out that the new network generated is still a scale-free network. Nodes with large number of linkage and the high technology proximity of nodes significantly affect the FDI spillover effect. However, the small-word property of scale-free network and nodes with different technology proximity will modify the effect of FDI spillover.
