本計畫目的為綜合整理國內外經濟效益分析方法，並研擬適用於本署水利工程經濟效益分析之工具。根據過去水利署過去與美國陸軍工兵團之交流活動中，了解該單位經濟效益分析已有完整之分析流程，分析結果不僅可提供決策者於規劃階段權衡最佳方案，計畫成果效益分析亦可做為民眾溝通之參考，其效益分析作法，可供水利署進行各項計畫效益分析時參考學習。考量我國國家發展委員會在資源有限情況下，發揮公共建設之預算效益，編訂「公共建設計畫經濟效益評估及財務計畫作業手冊」；此外水利署亦曾就水利工程經濟效益分析進行研擬，惟各類做法尚缺乏整合及應用。本計畫擬參考美國陸軍工兵團經濟效益分析方法，並通盤考量其他分析方法，研擬適用於水利署水利工程經濟效益分析之工具，使未來各大計畫進行效益分析有所依循。

This study aims to develop an engineer-operable manual for economic benefit analysis (EBA) on the hydraulic engineering projects of Water Resources Agency through investigating the studies carried out both by US Army Corp Engineers (USACE) and Water Resources Agency (WRA). USACE has a long history of implementing EBA for flood defense and other projects. Based on the analysis, the decision makers can trade off and select one from the candidate alternatives. The outcome of the EBA of projects can be also used for communication between the public and the officials.Cost and benefit analysis currently in Taiwan are demanded, based on the laws and regulations, to carry out; however, no reference manual can be referred when doing economic benefit analysis for a project. This study aims to develop a manual, based on those developed by USACE, that takes into account the economic theory and engineering practices for decision making and public communication, and can be easily operated by engineers.The study contains three major parts, including: (1) comparing the existing practices by the USACE and Taiwan with literature reviews and workshop discussions; (2) proposing a EBA procedure and tested with case studies; and (3) developing a draft manual that can be easily operated by engineers.The focus of the manual in this year is flood defense engineering projects. Through the manual, we expect the manual can be easily operated by the engineers and help them do a standardized EBA for the related projects.
