台灣產險業實施風險基礎資本額制度之適當風險係數探討 / An Analysis of Risk Factors of RBC System for Property-Liability Industry in Taiwan連婉儀, Lien, Wan-I Unknown Date (has links)
行政院會於民國八十八年十二月十六日通過保險法修正草案,修正草案中針對強化保險業之監理機制與增進保戶大眾之權益係以強化其資本適足性為其修法目標,所採之方法即建立風險基礎資本額制(Risk-based Capital, RBC)。而保險法修正案於民國九十年六月二十六日業已經立法院三讀通過,基於保險法相關條文規定,RBC制度將於民國九十二年中實施。
另一方面,美國經濟、社會及投資環境和台灣不盡相同,若將此制度直接或稍加修改即套用於台灣,將可能造成不切實際與誤導的作用,其結果不僅可能無法有效規範及避免保險公司失卻清償能力,亦可能因而造成龐大的社會成本,反而和當初建立RBC制度之原意背道而馳。因此,本論文即依循台灣產險業之產業特性制訂一套合宜之產險RBC制度,其中包括各個適當之風險項目及所屬之風險係數。
本論文在資產風險部分結合風險值(Value at risk, VaR)來計算資產之風險係數;在準備金風險以及自留保費收入風險則依照美國RBC制度之原始公式重新計算得來,惟準備金風險部分實因資料取得限制無法順利求出,為求模型完整性此部分本論文以財政部草案取代之;而於自留保費收入風險方面是採險種別及公司別。
研究結果發現:台灣產險的風險係數確實和美國產險的風險係數是有相當的差異,並且須根據台灣產業的經驗及配合我國的社會、經濟、投資環境並經由實際的運算才能得到適切的風險係數;而以論文所建立之RBC模型試算於各公司之風險基礎資本比則多有偏低之情形。 / Legislative Yuan has pass the draft of Insurance Law on June 26, 2001. In order to strengthen insurance regulation mechanism and to protect the insureds' benefit, the Risk-based Capital will be implemented in Taiwan Insurance market in 2003.
On the other way, the economic environment and investment markets in United State are different from those in Taiwan. If we directly imitate their RBC system in Taiwan, the outcome would be impractical. It not only can't regulate the insurers effectively, but also may cause huge social cost. Therefore, the purpose of the thesis is to establish a suitable risk items and suitable risk factors for Property-Liability insurance in Taiwan by our own empirical data.
This study finds that risk factors are significant different between Taiwan and American for Property-Liability insurance industry. The risk factors of the RBC system in Taiwan must depend on our own empirical data. I used the RBC model built in the thesis to test every Property-Liability company in Taiwan, and found that calculated Risk-based Capital ratios were relatively low.
