我國勞工保險開辦五十年來，隨著國人平均壽命的不斷延長，勞工保險被保險人的平均年齡亦不斷提高，造成勞工保險未來老年給付潛在負債的一大負擔。基此，為解決勞保未來的財務負擔，本文擬從開源面著手，針對現行「勞工保險基金管理及運用辦法」之規定，運用馬寇維茲(Harry M.Markowitz)所提出之效率前緣(Efficient Frontier)的概念，模擬出在不同既定報酬率下之最低風險投資組合的資產分配狀況。從本文的模擬結果中發現，勞保基金若能取消原運用及管理辦法中對各項得投資項目所規定的比重限制，改交由效率投資者來做最有效率的配置，則能有效地提高基金運用的報酬績效；同時，亦建議勞保基金能納入更多的投資項目，以達到風險分散的效益；此外，有鑑於國內現行長期性投資工具的不足，建議相關主管當局能進一步加以研究開發，以提供國內各項長期性基金一個完善的避險管道。

　　　　　From the beginning of the Labor Insurance in Taiwan in 1950, the average age of the insured has been increasing as the aging of the population, and which will lead to great potential liability of the future old age payment. For resolving the future financial crisis of the fund, this article simulates the minimum-risk portfolios under different given rate of returns by way of the "efficient frontier" concept proposed by Markowitz. Accordingly, for promoting the return of the Labor Insurance Reserve Fund, this article suggests abolishing the present regulations of the investment proportions of the chosen assets, and allowing the managers of the Labor Insurance Reserve Fund to make the allocation of the assets in the portfolio as efficiently as possible. In addition, the author also suggests taking more other securities into the Labor Insurance Reserve Fund in order to diversify risks, and also expects the authorities to develop some diverse long-term securities, which can offer more complete hedging assets to the long-term funds in Taiwan.
