    Abstract: 長壽是一體兩面的事,一方面享受到壽命延長帶來的好處,但又同時面臨到風險,因為在老年時將會受到經濟及醫療的威脅。面臨長壽風險的現在,死亡率的預測變的重要,到底未來死亡率將如何變化,人類的壽命又會延長到怎樣的地步,我們希望藉由死亡率模型來解決,若是模型可以預測未來死亡率的趨勢,那就可以提前做好準備。
    由以往的文獻指出,死亡率會受到總體經濟因素波動,由研究中發現死亡率與GDP的成長和失業率息息相關,而Lee-Carter 模型可以預測死亡率,如果將之結合是否能提升模型預測能力,本研究的做法是找出影響各國之間的顯著經濟變數,之後再與加入含有死亡率指數kt的回歸,如果在有死亡率指數的回歸中仍有顯著的經濟因素,那表示在使用Lee-Carter模型或經濟模型時也必須考慮到當時的經濟環境。
    There are two sides of same coin. On one hand, the extension of life is a good thing because we can enjoy our life longer. On the other hand, we also face longevity risk that we do not prepare enough money to afford living cost for extension life. Thus, to forecast mortality rate is a important thing because it can help us understand the longevity risk more accurately.

    From literature we can know that correlation between the mortality and macroeconomic fluctuations, and we can use Lee-Carter model forecasting future mortality. The purpose of this study is integrating these two factors to improve the mortality forecasting.

    In a first step, we investigate the relationship between mortality and change in marcoecomomic fluctuations. In second step, we investigate the the analysis including Lee-Carter mortality index kt and marcoecomomic fluctuations.

    Using data for twenty OECD countries over the period 1960-2009 and 1970-2009, this study finds that Lee-Carter model mortality index kt correlates significantly with marcoeconomic fluctuation, such as GDP、unemployment rate、participation rate、working hour. Furthermore, we also find that over half countries marcoeconomic are significant, even though the regression contain mortality index. We also find the mortality rate in some high social welfare countries have no significant correlation with macroeconomic fluctuations. The empirical result of this study suggests if we use model to forecast mortality rate, the macroeconomic factors should be involved in Lee-Carter model.
