由於現今市場上的新金融商品種類仍不能滿足各種避險者的需要，鑒於台灣目前仍沒有數位選擇權(digital option)的相關產品，且數位選擇權能為避險者減低避險成本的特性是值得被重視的，因此本論文對於另一個新奇選擇權：C-Brick進行較詳細的討論與實證分析。C-Brick是數位選擇權的一種，C-Brick有兩個標的資產，是一個多元數位選擇權，它能提供給擁有兩檔標的股票的投資者較低成本的避險管道。 本文將對C-Brick的價格行為、特質做進一步的研究，討論股價、波動度、相關係數等與C-Brick價格的關係。另外對delta做更詳細的分析。 在實證分析方面，利用建構避險部位的方式對C-Brick進行避險績效的分析，以聯電與台積電、南亞與台塑、合發與台積電為例子進行分析。為了探討避險績效之優劣本文將股價走勢分為上升、盤整、下降等三類探討股價變動對於避險績效的影響。同時也探討波動度對避險績效之關係。 最後，我們將C-Brick做較不同的變化：同時發行數個不同到期日、不同履約價的C-Brick，這樣除了讓這項商品更具吸引力外，我們也對此發行方法在避險考量上，做了可行與否的討論。

Web 2.0是一種架構在知識環境上的網路，使用者可以協同參與網站內容、工具和應用軟體的使用、發展與管理。為了創造更多使用者價值，各式各樣的Web 2.0新服務因應而生，例如：Wikipedia和Facebook，就是從這種服務導向的技術架構中衍生出來，進而提供有效的知識創造與社群互動。同時，由於Web 2.0平台具有協同合作與互動等特性，使用者的知識分享意願亦會受到平台中的知識與流程(即Web 2.0選擇權)所影響，因此，使用者參與和分享是十分重要的議題。 為了有效管理這類社群網路平台的知識創造與持續創新相關活動，本研究進行了兩階段的調查。在第一階段中，主要探索Web 2.0對於合作學習的知識創造服務。本研究分析並分類1,042個 Web 2.0 網站，進而定義出兩種知識創造服務平台(經驗交流型與智慧累進型) ，以及五種Web 2.0服務模式，包含交換模式、整合模式、組織模式、協同合作模式與開放模式，由於這些服務模式具體描繪出現有Web 2.0的不同應用，因此能清楚地闡釋Web 2.0科技的運用模式與價值建立。 第二階段本研究根據認知理論，調查知識貢獻者的分享動機，包括認知有用性、社群認同感、利他主義傾向、認知娛樂性和Web 2.0自我效能，以及Web 2.0選擇權對於分享意圖的調節效果。本研究對象來自於全球性樣本，即第一階段中兩大類型Web 2.0平台的貢獻者，經驗交流型平台蒐集了568位有效樣本；智慧累進型平台則有694位有效樣本。結果發現，Web 2.0選擇權會顯著地影響使用者的知識分享動機。對於經驗交流型平台而言，高度的知識與流程選擇權會顯著地調節知識貢獻者的社群認同感、利他主義傾向以及Web 2.0自我效能對於知識分享的意圖；對於智慧累進型平台而言，低度的知識與流程選擇權會顯著地調節知識貢獻者的社群認同感與認知有用性對於知識分享的意圖，而高度的流程選擇權則會調節貢獻者的認知娛樂性對於分享的意願。因此，組織在提供Web 2.0服務時，無論是為了人際交流目的或是知識累積目的，皆需要妥善地利用Web 2.0選擇權，才能有效建立良善的知識分享循環之平台。 / Web 2.0 is a network on which individuals contribute to the development and distribution of content, tools, and software applications over the Internet. To provide different values to the users, various innovative Web 2.0 services, such as Wikipedia and Facebook, have emerged from this omnibus technological concept, and the Web 2.0 platform has been praised for providing an effective platform for knowledge creation and group innovation. For a cyclical flow of knowledge generation and reinvention, user participation and contribution become the most critical part of the platform. Meanwhile, due to the collaborative and interactive features of the platform, this user intention can be highly affected by the Web 2.0 options—i.e., the reach and richness of knowledge and processes enabled on the Web 2.0 platforms. In order to effectively leverage this kind of social network platform for knowledge creation and innovation sustainment, this study has two stages. In Stage one, it explores Web 2.0 knowledge-creating services for collaborative learning. More than 1,000 Web 2.0 application sites were analyzed and classified, and two types of knowledge-creating services with five service models were identified. The two services are called experience-socialization and intelligence-proliferation, and the service models are coined with the names of Exchanger, Aggregator, Organizer, Collaborator, and Liberator. These service models represent the diversity of existing Web 2.0 applications and provide a base for better communications of the operating patterns and value propositions of the Web 2.0 technology. In Stage two, based on cognitive theories, it examines the determinants of knowledge sharing and the moderating effects of Web 2.0 options on the sharing intention. Motivators such as perceived usefulness, community identification, altruism tendency, perceived enjoyment, and Web 2.0 self-efficacy were verified by frequent contributors of all types. A global sample from contributors of two major types of Web 2.0 platforms, experience-socialization platforms (N = 568) and intelligence-proliferation platforms (N = 694), were collected. The results confirm that user motivations to contribute are moderated by Web 2.0 options. For contributors to experience-socialization platforms high knowledge and process options can affect their sense of community identity, altruism tendency, and Web 2.0 self-efficacy towards sharing intention. For contributors of intelligence-proliferation platform, low knowledge and process options affect the user’s sense of community identity and perceived usefulness that shapes their intention to share. By the same token, high process options affect contributors’ feeling of joyfulness towards contributing on the platform. Organizations providing Web 2.0 services for either socialization purposes or knowledge retention purposes need to leverage Web 2.0 options properly in order to build effective platforms and nurture a strong, growing stream of knowledge contribution.
