本研究應用資料包絡分析法，評估我國壽險業八年(2000年-2007年) 跨期實証期間的經營績效。在固定規模報酬(CRS)下，當所有投入變數皆為變動投入時，可發現靜態DEA中經濟不效率歸因於配置不效率，將固定資產假設為準固定投入後，顯示動態DEA中經濟不效率最大的原因為DE(Dynamic Efficiency)不效率，而DE不效率則源自於所觀察到之準固定投入不位於最適的路徑上。進而再將DE分解為DE=DEk*DEi。DEk可視為廠商在最適投資決策下，準固定投入的動態效率，DEi可視為廠商在最適投資決策下，投資於準固定投入之動態效率。本文發現DE不效率的最主要原因是DEk所形成之不效率。 The thesis mainly estimated efficinecy of Taiwan’s life insurance industry in the intertemporal period with Data Envelopment Analysis. The sample period spans from 2000 to 2007. Assuming that all inputs can be freely and instantly adjust to their optimal levels subject to constant returns to scale. Static DEA indicates that the static overall inefficiency of Taiwan’s life insurance industry originates from allocative-inefficient. After incorporating quasi-fixed inputs into the DEA model, the dynamic inefficient is due to an inefficient choice of the path of quasi-fixed inputs at observed levels.Next,DE is further decomposed into DEK and DEI. DEK is defined as the dynamic efficient to of the quasi-fixed inputs under the optimal investment decision;DEI is defined as the dynamic efficient to of the quasi-fixed inputs under the optimal investment decision.The result of DE inefficient originates from DEK
