Direct and indirect economic loss assessment of typhoon disasters based on EC and IO joint model

Abstract

In recent years, the typhoon disasters frequently occur, by which the economic loss caused is paid more and more attention. Combined with the uncertainty of real economy and the structure of detailed departments’ classification, traditional input–output models are extended in this paper. Moreover, static and dynamic models of economy and input–output are, respectively, constructed to evaluate the direct and indirect economic loss caused by typhoon disasters for related industrial departments. It is shown that when referring our proposed static model, the four dominant departments’ loss affected by typhoon in 2013 is 1271.9248 billion Yuan in total, accounting for 75.5303% of the total industrial product loss. In the case of the dynamic model, the longer the time of the sector returns to normal production, the bigger the cumulative economic loss caused by typhoon is.
