Crisis management is viewed as a new challenge in the domain of contemporary public administration; therefore, the capability to cope with crisis has become one of the indicators to judge how efficient the government can be. The fundamental theory of crisis management differs from what kind of viewpoint it takes. Taiwan has steeped into the stage of resolution or reconstruction since the 921 earthquake happened in 1999. As metioned in the president Chen's inaugural address, the new government has set the reconstruction job among the devastated areas as top priority and the traits of new grovernance, in simple words, are to go gradually from recovery of supporting system of necessities toward social and economic structure reform. To look back, the President declared the Emergency Decree soon after the 921 Earthquake (took place) and then announced the Temporary Act of the 921 Erthquake, working as the legal foundation, to succeed the recovery work as the execution of the Emergency Decree expires. Problems such as implementing the land rezone, the reconstruction of condominiums, employment measures for the unemployed and access to lands for housing the victims in the devastating areas have not yet been resolved less than half a year after the related act was announced. When the new government was established, the draft of the Amendment of the 921 Earthquake Reconstruction was proposed as priority to the Legislature for approval on Sep, 20, 2000 and eventually its third reading was passed on Nov, 10 in the same year. The mechanisms of post-disaster reconstruction in the U.S. and Japan will be introduced respectively first in this report, secondly an analysis on the three mechanisms of post-disaster reconstruction in Taiwan and thirdly the 18 key points about the amendment of the 921 Earthquake Reconstruction Act. Those mechanisms should be reviewed in an attempt to find out the norm of governance, which can be shared and considered as the reference of future post-disaster reconstruction.
