地震災害時のライフライン途絶が及ぼす経済被害の計量化に関する研究

抄録

A catastrophic disaster damages to lifeline facilities such as electric power, water and gas services, and it causes enormous effect on community life and business activity. However, building economic resilience can reduce the potential losses. This paper considers industrial resiliency to investigate measurement of economic impacts due to lifeline disruption. Using survey data from the Niigata-Chuetsu earthquake in 2004, the resiliency factor was firstly estimated so that it could take adaptive responses of industrial sectors into account. Secondly, with the estimated resiliency factor reflected on substitution parameters of production function, economic impacts of the earthquake were analyzed by a computable general equilibrium model.
