產險公司之再保需求的影響因素探討An Empirical Analysis of Determinants of Reinsurance Demand by Non-Life Insurance Co

摘要
本文使用國內13家產險公司1989至2004年之縱橫資料，及近似無相關迴歸估計技巧，探討公司特質因素對產險公司再保需求之影響。結果顯示，公司規模、保險槓桿、賠款變異性與保費收入成長率因素，對再保需求有顯著影響。不過，這些因素對再保需求影響情形，隨公司險種不同而有所差異。
關鍵字：產險公司、再保需求、近似無相關迴歸
Abstract
This paper uses the panel data of 13 non-life insurance companies from the year of 1989 to 2004, applying seemingly unrelated regression estimate, to explore how firm-specific factors effect on reinsurance demand. The results show that company size, insurance leverage, loss volatility and growth of premium are related to reinsurance demand. However, effects of the factors are varying across lines of insurance.
Keywords: non-life insurance companies, reinsurance demand, seemingly unrelated regression
