本研究以國內最大企業─台塑集團為研究對象,探討個案企業為何(Why)要採用自行建置的電子市集,以及哪些因素會如何(How)影響個案對電子市集的採用。依據文獻探討的結果,提出以成本、組織、產業環境等三個構面,建立初步的研究架構。經由個案研究的方法,分別對此三個構面為方向進行一系列的初、次級資料收集及訪談,藉以收集相關證據,再經由分析收集的證據來提出本研究的命題。 研究結果發現:影響個案採用電子市集的因素有: 1. 企業規模會影響採用:包含三方面,為台塑企業採購能量、台塑企業資訊科技能力、台塑企業財力。 2. 高階主管的決策與態度會影響採用。 3. 電子市集所帶來的相對利益會影響採用。 4. 台塑採用電子市集是建構在相關電子商務系統的成功經驗上,並持續修正過去系統的缺點,成為一個不斷演化的過程。 5. 台塑的組織文化會影響電子市集的採用。 目前台塑電子市集已經成為國內第一大電子市集,而台塑仍積極的招攬買方加入,欲藉由拉攏其他買方加入該市集,創造更大的購買商機,進而產生吸磁效應吸引賣方加入該市集。而這種大者恆大的優勢,會持續的發酵。 This paper discusses why Formosa Plastic Group (FPG), one of Taiwanese top Corps, adopts its own independent e-Marketplace, what factors affect the Corp, and how they affect the Corp. Based on the research paper, the research model is constructed and divided into three categories: Cost, Environment, and Organization. From each category in the research model, a series of data collection and interviews are done for the research proposal and further analysis. There are five factors in this research paper, as listed below: 1. Scale of the enterprise, which includes three categories: The ability of procurement, the ability of information technology and financial ability. 2. Top-level decision makers’ strategies and attitudes. 3. Comparative benefit of the e-Procurement system. 4. FPG’s e-Marketplace is constructed upon the continuous evolution of numerous electronic commerce system experiences. 5. The culture of the FPG organization. Currently, FPG owns leading e-Marketplace in Taiwan, and FPG still actively keeps on attracting buyers into its e-Marketplace. As more procurement ability is created, FPG is able to attract more sellers into the e-Marketplace. This chain reaction advantage will continue to grow in the feature.
