Based on defining the regional emergency response, nine important factors are chosen by employing the Delphi method, which are emergency response organizations, emergency response laws and rules, allocating emergency materials, allocating emergency teams, dynamic coordination of emergency preplan, communicating emergency information at once, regional geographical position, regional disaster features and regional cooperation basis.Meanwhile, ISM method is adopted to make sure the links between the nine factors and the inherent arrangements, that are basic layer, transitional layer, and direct layer, of regional emergency response factors is got by calculating the accessible matrixes and drawing the fourth diagraph.The three layers provide theoretical supports and scientific reason for building regional emergency response mechanism.%在界定突发事件区域应急联动内涵的基础上,采用Delplu法,识别出突发事件区域应急联动的9个主要影响因素,即应急联动组织机构、应急联动法律法规、应急物资协同调配、应急队伍协同调配、应急预案动态协同、应急信息实时沟通、区域地理位置、区域灾害特征和区域合作基础.同时,运用ISM技术,确定区域应急联动9个影响因素的关联性,计算和分解可达性矩阵,绘制4级递阶有向图,得出区域应急联动影响因素的内在层次性,即划分出"基础层"、"过渡层"和"直接层",为有效构建突发事件区域应急联动机制提供了理论支持与科学依据.
