内容简介：
In this study, we explore the characteristics of economic damage caused by a natural disaster and subsequent restoration by using a multi-regional recursive dynamic computable general equilibrium (CGE) model. A CGE model describes a whole economy as a non-linear simultaneous equation problem, and isconstructed based on traditional microeconomic theory and an input-output (I-O) table. OurCGE model divides Japan into eight regions (i.e., Hokkaido, Tohoku, Kanto, Chubu, Kinki, Chugoku, Shikoku, and Kyushu), with 23 industries in each region. A natural disaster is modeled as an exogenous reduction in the value of available capital stock and the productivity of the remaining capital stock and labor force. The process of economic restoration is modeled as capital accumulation in the affected regions through endogenous investment that can come from all regions. The affected productivity is assumed to recover exogenously.
