中文摘要：

以日本东南海地震为情景,以日本丰田汽车及其关联企业为例,基于工厂个体数据及其部件供应的拓扑和空间网络,模拟灾害风险在产业网络中扩散转移过程,建立直接损失与间接功能损失的评估模型,为产业空间网络风险评估提供新的思路和方法借鉴。结果表明：在东南海地震情景下,丰田汽车约48.1%的工厂将直接受损,其中生产设施损失约5587亿日元,厂房建筑损失约1980亿日元。由于关键工厂受损,将间接导致整个产业网络中断。在最长37日恢复情景下,将造成约9230亿日元的间接功能损失。地震灾害对丰田汽车产业网络影响显著,有必要采取有效措施进行减灾降险。

英文摘要：

Taking eastern Nankai earthquake in Japan as a hazard scenario and Toyota as well as its related suppliers as a case, based on individual data of auto plants and their topologicalgeographical supply network, we simulated the propagation process of disaster risk in industry network, and established the models for direct physical damage and indirect function losses assessment, which provides an alternative risk assessment method for industrial geographical network. The results show that in the case of eastern Nankai earthquake, 48.1% of Toyota plants would be directly damaged, of which the production facility losses and building losses would be about 5587 billion yen and 1980 million yen, respectively. Due to the damage to some critical plants, it would indirectly lead to functional interruption of the industrial network.In the scenario of 37 days of recovery, the indirect monetary losses were estimated to be approximate 9230 billion yen. The threats and impacts of eastern Nankai earthquake disaster on the Toyota industrial network are significant, and it is necessary to take structural and nonstructural measures to reduce the risk.
