摘要

有些民間參與投資(BOT)之計劃，因在政府規劃階段風險性較高，評估之預期淨現值爲負，而對投資人不具吸引力，然而，當外在環境及市場較確定時，即可能成爲一個財務可行的計畫。若政府給予BOT的特許投資人一個選擇的權利，對計畫的擴充及終止有決策權，將可提高計畫的可行性。本研究主旨在分析給予投資人決策彈性，對提高BOT計畫可行性的效益。本研究以高雄第一港口觀光纜車計畫爲個案，先使用現金流量分析法作爲財務規劃評估之基礎，繼而透過蒙地卡羅模擬預估計畫效益之淨現值，以及可能損失之風險，再用二項式選擇權訂價模式，評估給予特許投資人擴充及提前終止之選擇權，對計畫價值的影響。

Some private participation projects reveal high risk with negative expected net present value (NPV) and are therefore not viable as private investments in the planning stage. However, as the external environment and the market become more certain, these projects might become financially feasible. The viability of the project may be improved if the host government offers concessional investors the options or rights to expand or terminate the project in response to environmental changes. This paper aims at presenting the effect of decision flexibility on project feasibility, using the Kaohsiung Cable Car Project (the Project) as an example. We developed the pro forma cash flow of the Project as the base case. Monte Carlo simulation was conducted subsequently to estimate the expected NPV and the probability of loss. Binomial option pricing was then used to measure the effect of the options to expand and terminate project value.
