氣候變遷加劇全球各地天然災害。基於保障人民基本生活，政府主動積極管理災害風險已不可避免，而國際上亦普遍以保險機制調適氣候變遷風險，且建立公私合作關係共同承擔巨災損失。本文整理分析文獻資料作為論述基礎，並比較研究國內外天然災害保險制度，歸納整理共同特性與功能，以及建立制度之基本原則與經營基礎，以演繹我國天然災害保險制度法制化重點包括：1.立法形式：單獨特別立法建立制度；2.政府角色：兼具保險人及再保險人角色，提供天災保險保障並具風險承擔功能；3.制度模式：在公私合作關係下，由民營保險人負責銷售管理、理賠且承擔中間規模損失，而政府提供財務支持或擔保；4.制度定位及性質：屬於非社會保險之公共計畫（政策保險），人民無投保之法律上義務；5.保障範圍：規範最低承保範圍，提供人民一致且可負擔之保險；6.減災責任及誘因：保險制度應整合減災，納入個人減災誘因且於利害關係人間（政府、被保險人、保險人）適當分攤減災責任；7.主管機關與專職管理組織：減災為天然災害保險不可分割之一部分，宜跨越行政組織分工，從功能性意義上互動共同治理；並將住宅地震保險基金轉型為天然災害保險基金作為專職管理組織；8.風險分散機制：立法設置多層次風險承擔機制，由被保險人自負低層小額損失，保險人、天災基金、再保險人、資本市場承擔中間層級責任，政府則承受極端重大損失。 / Climate change has intensified natural disasters worldwide. To protect people’s basic livelihoods, it is necessary that the government actively and aggressively manages the risks of disasters. Meanwhile, insurance system is an adaptation measure generally adopted to pool the risks of climate change, and public and private cooperation is established to share the losses of huge disasters. This study compared domestic and foreign insurance systems aiming at natural disasters based on the summary and analysis of literature to develop the keys legislation regarding a natural disaster insurance system: 1. Type of legislation: individually established legislative system; 2. Government role: both the insurer and re-insurer providing protection and risk assumption for natural disasters; 3. System model: with public and private cooperation, private insurers are responsible for the sales, management, claims and assumed losses on a moderate scale, while the government provides financial support or guarantees; 4. System positioning and nature: the public plan other than social insurance, people is no generalized duty to buy cover in the system; 5. Coverage: minimum protection, providing consistent and affordable insurance to all people; 6. Mitigation and incentives: the insurance system should integrate mitigation with personal incentives for disaster reduction and share mitigation responsibilities among stakeholders (government, insured, insurer) as appropriate; 7. Competent authority and dedicated management organization: mitigation is an inseparable part of natural disaster insurance, which is appropriate for the work divisions of cross-administrative organizations and interactive governance in functions; turn the Taiwan Residential Earthquake Insurance Fund into a natural disaster insurance fund for dedicated management; 8. Risk diversification mechanism: set a multi-level risk sharing mechanism through legislation, in which the insured shall be responsible for low-level losses in small amounts; the insurer, natural disaster insurance fund, re-insurer, and capital market share the middle-level liabilities; and the government shall bear the extremely large losses.

根據世界銀行的資料顯示，佔全球面積約19%的2500萬平方公里之地球表面，及佔全球一半以上人口的34億人是相對的暴露在一個以上天然災害之威脅下。隨著全球化的來臨，我們居住在一個風險共享的社會中，而在全球環境安全被視為全球公共財的同時，如何在集體行動的邏輯下進行全球危機管理，已成為全球行動者的主要課題。例如如何透過國際合作來對抗SARS，禽流感等危機，皆是當前全球行動者關注的議題。值得注意的是，儘管近二十年來國際社會對於減災所做的承諾與投入的資源日益增加，災害所造成的經濟損失及受到災害影響之人口卻也逐漸上升。面對這些現象，本研究最主要想要探究的研究問題即在於什麼樣的因素影響著全球減災合作。 本研究主要的研究問題，係探求在全球行動者為何要參與減災合作，而此全球減災合作又如何運作的呢？全球減災合作、理性選擇與全球社會資本的分析架構將被運用。從理論上粹取的因素，例如風險意識、能力素養、偏好、制度限制、資訊、可信的承諾與信任等，被用來分析行動者如何決定參與合作，以及此合作如何運作。鑑於2004年印度洋海嘯所造成的重大傷亡以及後續國際社會對救災及減災的承諾，本研究將以印度洋海嘯預警系統的個案為例，並透過在4個國家共計22人次對參與此系統的國際行動者之訪談資料，以及對參與印度洋海嘯預警系統之人員發放共計591份問卷進行調查及分析，回收問卷目前共計61份，然進行論文分析時為59份。換言之，實際上的回收率為10.66%，而本研究用以分析之問卷回收率為10.32%。本研究最主要的發現為風險意識及能力素養的提升，結合理性選擇與社會資本的不同因素作用下，將對全球減災合作的結果有正面的影響。最後，本研究也對未來國際減災合作提出相關之建議。 / Writing on the issue of global environmental security, the World Bank has noted that approximately “25 million square kilometers (about 19 percent of the Earth’s land area) and 3.4 billion people (more than half of the world’s population) are relatively highly exposed to at least one hazard.” With the coming of the globalization era, we .also live in a shared risk society. Since global environmental security is seen as a global public good, how to act for global crisis management under the logic of collective action has become a primary subject for global actors. Coping with the crises of SARS or Bird Flu through international cooperation has become a significant issue for these global actors. One of the main dilemmas of international cooperation for disaster reduction is the reconciliation of different individual actions. Interestingly, in spite of two decades efforts of international cooperation, the amount of damage caused by natural disasters and the total number if people affected have gradually increased since the 1960s. This research focuses on two questions in the present research: why do global actors cooperate in disaster reduction, and how does this cooperation operate? The frameworks of international cooperation in disaster reduction, rational choice and global social capital are employed here, to explore the issue of international cooperation. Several factors, such as awareness of risk, capacity, preferences, institutional constraints, information, credible commitment, and trust, are used to examine how an actor engages in decision-making and how cooperation occurs. Because of the tremendous damage that resulted from the Indian Ocean tsunami of 2004 and the engagement of the global society in disaster recovery and reduction, the above issues will be explored through a case study of the development of the Indian Ocean Tsunami Warning System (IOTWS). Twenty-two interviews were conducted in four countries and these constitute the qualitative data for this analysis. 591 questionnaires also have been sent to the participants in the IOTWS to collect the quantitative data. I analyzed the quantitative data from 59 returned questionnaires (10.32% returning rate) and the qualitative data from 22 interviewees in four countries. These analyses resulted in several suggestions to facilitate international cooperation for disaster reduction.
