在未來的無線點對點環境中，由於資訊將被賦予金錢上的價值，故核心議題將不在於如何解決資訊便車者問題，而是必須針對有價資訊制定一有效的定價模式以促進個體提供差異化服務的意願。本研究所提出之情境式小額定價模式，以價值導向定價為基礎，除了針對個體本身資源限制考量而設計之外，更考量服務本身之特性(如無形性、不可分割性、異質性與易逝性)，因此可有效地針對個體目前所處的情境需求以協助服務買方與賣方分別制定服務價格策略與價格談判策略，讓買賣雙方可快速地達成協議。 本研究期望藉由情境式定價與談判機制的提出，能對WP2P 的無線應用服 務發展有所貢獻，並期望讓使用者在動態且即時的環境下，能有效地促進資訊分享的意願與流通，進而能恣意地享受行動服務所帶來的全新生活體驗。 / In the foreseeable Wireless Peer-to-Peer (WP2P) environments (in which information traded is associated with monetary value), one of the key issues in WP2P will focus on how to build efficient pricing strategies to facilitate the peers’ willingness of offering differentiated services (rather than the status–quo of merely resolving the free rider problems). Accordingly, this paper presents a contextualized micro pricing strategy for e-services operating in distributed WP2P environments. The pricing strategy grounding in the concept of value-based pricing not only takes mobile device restrictions and attributes of the surrounding context (ex. time, location) into account, but also regards the unique features of services (intangibility, inseparability, heterogeneity, perishability) to assist service buyers and sellers to rapidly come to a deal with each other in terms of a lightweight pricing/bargaining process. The contribution of the proposed contextualized micro pricing strategy is to improve peers’ willingness of furnishing differentiated services and to enhance the distribution of the service resources amid the WP2P environments.
