摘要

異質採購是最有利標採購方法的重要基礎，然而過去卻一直缺乏一套量化分析理論，致使採購人員在選擇決標模式時缺乏客觀依據而易產生爭議。本文以經濟學之效用函數為基礎，參酌文獻中有關效能與價格關係以及價格彈性等理論，建構一套結合價格（Price）與效能（Performance）之異質採購分析方法，稱為「價格效能分析模式（P/PAM）」，以建立機關異質採購決標模式之理論分析基礎。本文除建立P/PAM 之數學模式外，並提出以「市場效能彈性（E（下標 m））」做為判斷異質採購的衡量指標，最後以營建專案常見之財物採購及統包工程採購為例，說明該模式於實務上之應用，並針對實務應用之相關課題進行探討。

Heterogeneity of procurement is essential for Best Value (BV) tender selection. However, there was no theoretical model developed for analysis of the heterogeneity of tenders. It has caused difficulties for the procurement personnel of public agencies in determining the most appropriate tender selection method. The present research aims at developing a quantitative model, namely Price/Performance Analysis Model (P/PAM), for analysis of the heterogeneity of tenders of a procurement project. The P/PAM was developed based on several related fields including the utility functions, price/performance relationships, and price elasticity. The paper describes the mathematic model development of P/PAM and proposes a ”Market Price Elasticity of Performance (E (subscript m))” as an index for measuring the heterogeneity of tenders of a procurement project. Finally, two practical procurement examples, including a product procurement project and a design/build (D/B) construction project, are demonstrated with the proposed P/PAM to illustrate the applicability of the proposed model. Practical issues related to the adoption of P/PAM are also addressed.
