  3. But my focus was specially laid on the decision - making of investment under uncertainty and with competition, i first. extend the basic model of dixit & pindyck ' s by allowing the relevant parameter to be a random variable, then proposed an numerical example to show how to solve this model, i gave the algorithm and did the comparative static analysis, finally i developed a model of duopoly under uncertainty, considering the competition between the firms explicitly, using roa, i calculated the two firm ' s values respectively when they take different roles - to be leader or follower, and then checked the possible equilibriums

    本文的重點是考察在同時存在不確定性和競爭的情況下，如何用實物期權的理論估算投資項目的價值，為此，文中發展了兩個模型，第一個模型是對dixit & pindyck的模型的擴展，它通過一個相關的隨機變量來考察競爭對項目價值的影響，但沒有考慮企業間的相互博弈，文中給出了一個例子詳細地說明了該模型的求解並做了敏感性分析；第二個模型是一個不確定情況下的雙寡頭模型，文中給出了用實物期權方法計算的兩企業在處于領導者和跟隨者兩種不同境況時的價值，並將企業間的相互博弈考慮在內，考察了可能的均衡狀態。
