    Abstract: 汽車保險是與消費者關係最為密切的財產保險,但或許因為國人對汽車保險的認知不足,至今仍存在不合理現象。例如:近年汽車車體損失險的投保率下降且損失率逐年上升,其原因或可歸咎於現行的保費不見得反映實際的風險,但此有違精算費率精神的現象若持續下去,勢必對汽車保險的財務健全有不良影響。本文採用國內某產險公司1999 年至2002 年汽車車體損失保險資料,探討保費收入與理賠支出的關係,希冀在滿足保費均衡的原則下,尋求較小變異數的預測方法,以降低風險。本文考量過去用於產險的最小誤差估計法,以及根據經驗建構模型的類神經網路法,比較這兩種方法何者較能降低分類的誤差與縮小個體的誤差,以期保費收入與理賠支出兩者間有較小的差異。實證結果顯示,現行國內車體損失險不完全符合保費均衡原則,其間仍存在保險補貼。而在模型配適上,最小誤差估計法計較能改善收支不平衡的現象;而類神經網路法的加減費系統具有較大加減幅度,更能有效區分高低風險群組,降低不同危險群組間的補貼現象,並在跨年度的資料中具有較小的誤差變異。
