基于2008年桂林冰雪灾害相关统计数据,应用社会网络分析方法,增加时间维度,研究非常规突发事件跨组织合作网络结构的演化机理。通过网络结构的整体测度,分析把握不同时期合作网络结构的整体特征,划分应急阶段;基于组织角色测度指标,识别并分类合作网络中的应急组织角色;系统分析网络结构演化的动力因素,厘清相互作用方式,归纳因素的驱动模式,解析合作网络的演化机理。
Based on the statistics of 2008 Guilin snowstorms, this paper adds time dimension to analyze structural evolution mechanism of cooperation network over time by using SNA. Based on structural indexes, it analyzes overall characteristics of cooperation networks, divides emergency management into different phases. Based on calculating role indexes, it divides or- ganizations into different categories. After that, it analyzes the key factors of network evolution, clarifies the mode and drive pattern of them, and analyzes the evolution mechanism of cooperation network.
