Research on the Coordination between Urban Disaster Carrying Capability and Economic Development

Email: [email protected] ABSTRACT: Generally, the urban disaster carrying capability in economic developed cities were considered better than the developing cities for wealth and the better capability could help for decreasing relative loss even though absolute loss under disasters maybe higher in economic developed cities. That was to say that the urban disaster carrying capability interacted with the urban economic development. The grey relation entropy approach was used to analyze the coordination among all capabilities such as disaster defending, resistance, rescue and recovery which were assessed by a series of indexes, as well as the relational intension between the integrated disaster carrying capability and economic development level. High relational intension couldn’t account for good coordination, so that based on the grey system theory, the coordination between urban integrated disaster carrying capability and urban economic development was analyzed. It was found that the coordination was not very well supposed due to the time delay of the capability to economic development. After time series parallel stepped, the consequence of delay was proved and the coordination was improved too. In the authors’ view that the urban integrated disaster carrying capability interacted with the urban economy, and mean time, expediting the integrated capability to be perfect could decrease the urban relative loss under disasters.
