| 摘要: | 近年來各國逐漸採用成效式契約(Performance-Based Contract, PBC)，重視履約的成果和成效，在各個領域應用的效益受到肯定，但如何建立客觀且具說服力的成效評估架構以利推廣，對於欲使用PBC的單位仍是一大挑戰。臺北市工務局透過工務建設科學研究創新計畫，以市區道路日常巡查修繕作業導入成效式契約之領域為標的，以滿足道路使用者、機關、廠商的需求為主軸，建立成效指標、監督機制，以及付扣款機制等PBC重要契約內容，本研究以該科研計畫成果作為基礎，進一步發展此類型成效式契約的成效評估架構，內容包含1項質化與8項可量化的成效評估項目。為驗證提出之架構的可行性，本研究針對先前試辦成效式契約之專案，發展利用效益成本比率法(Benefit-Cost Ratio, BCR)計算導入PBC成效之成效評估方法。經由驗證結果顯示，質化成效評估項目PCI評級可達滿意等級，表示在維護品質確保上可行；量化成效評估項目中，考量道路使用者、機關、廠商三者面向指標的整體BCR為3.58，表示在經濟效益上為可行。本研究建立的成效評估架構與評估方法，可做為其他單位評估是否導入PBC以提升工作成效之評估工具，對於推動PBC的應用帶來實質幫助。另外，本研究利用兩階段專家訪談，篩選成效式契約的關鍵成功因素共12項，並建立與機關因應對策之間的關聯性，研究成果可供機關作為導入成效式契約的參考。;Performance-based contracts (PBC) have been adopted increasingly in various countries. The results and outcomes of contract performance have been valued, and the benefits of their application in various fields have been recognized. However, establishing an objective and convincing benefit evaluation framework to facilitate promotion remains a major challenge for those who wish to use PBCs. In a previous research project in Taipei City, the focus was on introducing PBC into the daily inspection and repair operations of urban roads, with the primary goal of meeting the needs of road users, authorities, and contractors. Key contract elements of PBC, such as performance indicators and payment/deduction mechanisms, were established in this pilot program. Building upon this foundation, the current study further develops a performance evaluation framework for this type of PBC, comprising one qualitative and eight quantitative performance evaluation criteria. To validate the feasibility of the proposed framework, the study targeted a previous pilot project that implemented PBC. This study uses the benefit-cost ratio (BCR) method for the pilot program. It calculates the effectiveness of introducing PBC to verify the feasibility of the proposed framework. The validation results show that qualitative benefit evaluation using the Pavement Condition Index achieves a “satisfactory” rating, indicating it ensures the quality of road maintenance. For the quantitative benefit evaluation, an overall BCR of 3.58, considering road users, authorities, and contractors indicators, suggests that it is economically viable. The benefit evaluation framework developed in this study can be used as a simple and easy-to-use evaluation tool for other organizations to assess whether to introduce PBC and can help promote the use of PBC. Additionally, through a two-stage expert interview process, the study identified 12 key success factors for Performance-Based Contracts and their correlations with strategies for agencies to cope, offering valuable insights for agencies considering the adoption of PBC. |
