臺灣高速鐵路、高雄捷運工程及高速公路ETC 等案件，衍生諸多履約爭議，引起社會矚目。我國於2000 年2 月制訂「促進民間參與公共建設法」，旨在引進企業資金及經營理念，完成基礎建設，以減少政府財務負擔，並帶動民間商機增加就業機會。國際上，謀以前述之公私協力方式帶動國家經建發展者，有聯合國國際貿易委員會於2001 年所制定之「私人融資公共建設法律指南」為他山之石，足供吾人借鏡。依我國促參法第47 條規定，申請人與主辦機關於申請及審核程序之爭議，準用政府採購法規定。同法第48 條規定，依BOT 方式興建、營運之公共建設，不適用政府採購法之規定。對與日俱增之BOT（指建設－經營－移轉即Build-Operate-Transfer）投資契約爭議，究採民事訴訟、仲裁或行政訴訟解決，至今仍有不同見解。經分析探討，本文將BOT 投資契約定性為私法契約，惟行政機關得依法干預。觀諸2010 年公共工程委員會所修訂之「促參案件招商文件及投資契約範本」第24 章爭議處理及仲裁條款之規定，本文主張以仲裁解決BOT 專案的履約爭議，具有專業、迅速、經濟及保密等優點；為曠時費日之訴訟程序所不及。且仲裁程序對法律適用之嚴謹與訴訟程序並無二致，其仲裁判斷之公平性、合法性咸為當事人及社會所高度期待；實係重大工程法律爭議最有效率之解決方式。未來關於BOT 投資契約爭議將日益增多，選擇仲裁制度有效並快速解決紛爭以免訟累，其於契約目的之達成及工程品質之提升，對國家之競爭力將有長遠之影響。

The BOT cases, like Taiwan High-Speed Railway, the Kaohsiung Mass Rapid Transport, and the Taiwan Highway ETC, etc., raise many disputes about contract performance, and draw a lot of social attention to them. Taiwan Government established “Promotion of private participation public construction law” in February 2000, and hoped the introduction of private enterprises’ budget and management model in the infrastructure not only reduce government finance burden but also bring along business opportunity. In 2001 United Nations International Trade Committee formulated “Guide of private finance for public construction” in order to create economical planning and development by the public private partnership. The article 47th of Taiwan BOT law stipulates that “The disputes between the applicant and the sponsor institution in the application and the approve formula should based on the government procurement law. And the article 48th stipulates that “The public construction and running based on BOT law are independent of the government procurement law.” In fact of the increasing BOT disputes, it is still unsettled in adapting civil action, arbitration, or the administrative proceedings to solve them. This claim should be characterized as a private contract of BOT contract at execution stage; the administrative authority may intervene in accordance with the law. In 2010 the Public Construction Committee Amendment “Samples of Tender Document and Investment Agreement for Promotion of Private Participation”, Chapter 24 for dispute resolution and arbitration clause, be specified. Therefore, the disputes will be settled by the arbitration on BOT contract, with a professional, fast, economical and confidentiality, etc., stronger than litigation. Although the arbitration is not strict as litigation on the lawful basis, but the fair and reasonable of the arbitral award are highly expected from the parties of the BOT contract and the community, and less impact on the scheduling of the project by arbitration. Hopefully, the disputes over the BOT investment contract can be solved by arbitration as much as possible, and our society and public construction could benefit from it.
