Based on the data of Auto Parts Firms, we model the Directed Weighted Competitive Pressure Networks and make a simulation analysis on the rivalry spread effect over this network. We discover that the higher the out weight of the initiator the heavier the rivalry spread effect over the network; meanwhile the higher the out weight edge is chose the larger the range of the rivalry spread effect. Next, we identify that the rivalry spread effect is limited within a range, although the rivalry action is initiated by different firms and different products. Further, we find that the affected ranges are tightly related to community to which the initiator belongs. Finally, we analyze the simulation result from the economic perspective.%基于我国汽车零部件企业的数据,构建了有向加权的竞争关系复杂网络模型,在此网络上对竞争扩散效应进行仿真研究.研究发现,有向加权竞争网络中,外向点强度越大的节点发起的竞争行为导致的扩散效应越大;选择边权越大的相连节点发起竞争行为导致的扩散效应越大;由不同企业通过不同产品发起的竞争行为,其最终扩散的范围都是有限的,而且扩散的范围与发起企业所在的社团边界密切相关.此外,对仿真结果的经济学含义也进行了分析.
