This paper, based on governance theory and social capital perspective, investigates the implementation difficulties and dilemma of 921 earquake disaster relief and reconstruction project. The paper also proposes a crucial theoretical argument of how to upgrade emergence management capability in dealing various disasters. Actually, emergency management is a complicate and difficult public service delivery for any public authority. It is improper to look for disaster relief strategy from traditional public administration. Efficient and effective emergency management should be based on newly emerging governance model which emphasizes the cooperation between the government and civil society since the private sector has large potential resources to be used in disaster relief and recovery program implemented by government. Generally, disaster relief is urgent and time-pressured public service. Governments with traditional hierarchical organizational control system are usually ineffective in dealing compelling disaster relief. Social capital approach, characterized with three key elements of trust, norms, and social networks, points out that there are potential resources, including humanitarianism, trust, donation, and organizational networks which could be mobilized to improve government performance in general and upgrade emergency managerial capability in particular. The government should figure out an institution setting to effectively create and mobilize social capital to improve government's emergency management capability. According to this bitter 912 earthquake disaster experienced by Taiwan's government and society, this paper emphasizes that facing new-millennium public administration, we should move from "government paradigm" into "governance paradigm".
