应急物资是否足量储备是影响后续救援调度的关键。现实世界的应急物资储备方式是多源的，因此多源物资的协同储备就成为应急准备阶段的关键问题。根据实地调研的数据计算出上海市某区域的交通事故的密度函数，借用需求连续随机的存储模型对该地区的最优资源存储量进行计算，发现区域内应急救援物资储备的绝对数量不足，而且多个储备源间的调度障碍很大，应急救援调度会出现严重的困难。针对该问题，使用结构方程模型，通过调查问卷的形式得出应急救援物资储备协同的影响因素。问卷数据验证了模型的有效性和拟合程度，进一步通过路径系数检验出结构方程模型整体的拟合度。研究发现：事件因素、技术因素、部门权限因素以及部门沟通因素均可以通过正向影响信息沟通共享机制进一步正向影响应急救援资源的协同储备能力。并对该地区的应急救援物资协同制度改进路径提出可行性的建议。
應急物資是否足量儲備是影響後續救援調度的關鍵。現實世界的應急物資儲備方式是多源的，因此多源物資的協同儲備就成為應急準備階段的關鍵問題。根據實地調研的數據計算齣上海市某區域的交通事故的密度函數，藉用需求連續隨機的存儲模型對該地區的最優資源存儲量進行計算，髮現區域內應急救援物資儲備的絕對數量不足，而且多箇儲備源間的調度障礙很大，應急救援調度會齣現嚴重的睏難。針對該問題，使用結構方程模型，通過調查問捲的形式得齣應急救援物資儲備協同的影響因素。問捲數據驗證瞭模型的有效性和擬閤程度，進一步通過路徑繫數檢驗齣結構方程模型整體的擬閤度。研究髮現：事件因素、技術因素、部門權限因素以及部門溝通因素均可以通過正嚮影響信息溝通共享機製進一步正嚮影響應急救援資源的協同儲備能力。併對該地區的應急救援物資協同製度改進路徑提齣可行性的建議。

Whether the reservation of relief supplies is adequate impacts emergency rescue.In reality,relief supplies are reserved at different places,therefore the collaborative relief supplies preparation is a key problem in emergency prepara-tion.In emergency preparation is of top priority.Taking traffic emergency as an example,in a given Shanghai municipal district,we first employed the inventory model to calculate the optimal stock of the required relief supplies.We found that there are insufficient relief supplies in this district,and it's hard to transfer the supplies,thus the emergency rescue will be an inefficient one.Aiming to solve this problem,we employ SEM.A questionnaire was thus designed to figure out factors that have impact on the collaborative emergency supplies preparation.After the reliability,validity and other parameters of the questionnaire are checked,model is also tested in its fitness through the path coefficient testing.We find that event characters,technology ability,agency authorization and inter-agency communication have a positive impact on the infor-mation sharing ability across government branches,and furthermore,have apositIve impact on the emergency relief reserva-tion in this area.Suggestions were given from two aspects including the improvement of coordination level and the order of optimal stock.
