A city has its specific GDP constitution of industries, while each constituent industry has specific characteristics. In earthquake disasters of certain degree, consequential damages brought to each industry are different due to different characteristics, this breaks the harmony in the constituent industries, results in the occurrence of choke point in the industry chain, and therefore interferes the running of entire civic economy. In this paper, the influence of industry loss in earthquake to civic GDP is studied through input-output analysis, and described by the defining of two variables as direct influencing factor to GDP and indirect influencing factor to GDP, which could provide scientific reference for the effective deploying of disaster-reduction resources, therefore enhance the utilization of disaster-reduction resources.
