簽訂自由貿易協定之貿易與福利效果 / Estimates of the Trade and Welfare Effects of FTA

吳米琪, Wu, Mi Chi Unknown Date (has links)
近年來雙邊甚或區域間簽訂自由貿易協定之風盛行,本文欲探討其影響。參考Caliendo and Parro(2015)的方法,以考慮部門異質性、投入產出連結以及中間財貿易之模型,計算1995-2013年間三個模型的福利效果。旨在分別檢視1995-2005年間WTO成立十年之影響、2005-2013年間全球120份自由貿易協定生效之效果,以及韓國此段期間內簽訂自由貿易協定之成果。本文結果顯示,WTO於1995年成立至其後10年間,確實為會員國帶來正面影響,總體而言,多數國家福利效果變動率為正。到了2005-2013年,全球有120份區域貿易協定生效,亦提升多數國家的福利,然成長幅度不如1995-2005來的顯著。惟韓國受惠於其簽訂自由貿易協定的成效,福利成長得與先前維持相近水準。此外,透過不同模型間的比較,本文發現各模型間的福利效果有明顯差異,顯示現今複雜的國際分工鏈下,完善考量部門間的互動因素實為衡量國際貿易效果的重要課題。

巨量資料環境下之新聞主題暨輿情與股價關係之研究 / A Study of the Relevance between News Topics & Public Opinion and Stock Prices in Big Data

張良杰, Chang, Liang Chieh Unknown Date (has links)
近年來科技、網路以及儲存媒介的發達,產生的資料量呈現爆炸性的成長,也宣告了巨量資料時代的來臨。擁有巨量資料代表了不必再依靠傳統抽樣的方式來蒐集資料,分析數據也不再有資料收集不足以致於無法代表母題的限制。突破傳統的限制後,巨量資料的精隨在於如何從中找出有價值的資訊。 以擁有大量輿論和人際互動資訊的社群網站為例,就有相關學者研究其情緒與股價具有正相關性,本研究也試著利用同樣具有巨量資料特性的網路新聞,抓取中央新聞社2013年7月至2014年5月之經濟類新聞共計30,879篇,結合新聞主題偵測與追蹤技術及情感分析,利用新聞事件相似的概念,透過連結匯聚成網絡並且分析新聞的情緒和股價指數的關係。 研究結果顯示,新聞事件間可以連結成一特定新聞主題,且能在龐大的網絡中找出不同的新聞主題,並透過新聞主題之連結產生新聞主題脈絡。對此提供一種新的方式來迅速了解巨量新聞內容,也能有效的回溯新聞主題及新聞事件。 在新聞情緒和股價指數方面,研究發現新聞情緒影響了股價指數之波動,其相關係數達到0.733562;且藉由情緒與心理線及買賣意願指標之比較,顯示新聞的情緒具有一定的程度能夠成為股價判斷之參考依據。 / In recent years, the technology, network, and storage media developed, the amount of generated data with the explosive growth, and also declared the new era of big data. Having big data let us no longer rely on the traditional sample ways to collect data, and no longer have the issue that could not represent the population which caused by the inadequate data collection. Once we break the limitations, the main spirit of big data is how to find out the valuable information in big data. For example, the social network sites (SNS) have a lot of public opinions and interpersonal information, and scholars have founded that the emotions in SNS have a positive correlation with stock prices. Therefore, the thesis tried to focus on the news which have the same characteristic of big data, using the web crawl to catch total of 30,879 economics news articles form the Central News Agency, furthermore, took the “Topic Detection & Tracking” and “Sentiment Analysis” technology on these articles. Finally, based on the concept of the similarity between news articles, through the links converging networks and analyze the relevant between news sentiment and stock prices. The results shows that news events can be linked to specific news topics, identify different news topics in a large network, and form the news topic context by linked news topics together. The thesis provides a new way to quickly understand the huge amount of news, and backtracking news topics and news event with effective. In the aspect of news sentiment and stock prices, the results shows that the news sentiments impact the fluctuations of stock prices, and the correlation coefficient is 0.733562. By comparing the emotion with psychological lines & trading willingness indicators, the emotion is better than the two indicators in the stock prices determination.

Argument-Function Linking in Yami:An Optimality-Theoretic Account / 雅美語的論旨角色與語法功能連結:以優選理論分析

鄧敦弘 Unknown Date (has links)
本論文旨在描述並嘗試以優選詞彙功能語法理論(OT-LMT)處理雅美語的論旨角色與語法功能的連結。雅美語的論旨角色與語法功能連結呈現出作格語言的特性,以致跟中文或英文有很大的差別。並且雅美語的連結又受到了焦點系統的影響,所以更加的複雜。現存的連結理論無論是以變換語法理論為基礎或以詞彙語法為基礎的,似乎都無法很直接簡潔的描述雅美語。本論文嘗試架構一個以優選理論為基礎的新連結模型,並且除了將之使用在雅美語上之外,也同時以這個新的模型來處理中文和英文中的連結。由於優選理論具有彈性的特性,這三種語言不同的連結模式,都可以被包含在這個新的模型當中。 / This thesis studies the problem of argument-function linking in Yami and makes the fundamental claim that linking in Yami shows an ergative pattern, quite different from that in accusative languages, such as Mandarin and English. The linking phenomenon in Yami is complicated by its special voice system. Existing linking theories do not account for Yami straightforwardly. In trying to find a framework that can handle the Yami data, we find the flexibility of Optimality Theory a promising solution. The first part of this thesis is a description of the argument-function linking pattern in Yami and the proper place of the voice system is also discussed. And then we review several grammatical theories on linking. Both transformation-based theories and lexicalist theories are examined. We will demonstrate how these theories fail to account for linking in Yami in a straightforward manner. Thus we provide an optimality-theoretic account based on the lexical mapping theory of Lexical-Functional Grammar. This newly developed framework is applied not only to the Yami data but also to the relevant Mandarin and English data. It is claimed that this framework can accommodate all three different languages.

連動式債券設計個案研究-固定期限交換利率利差連動與信用連結債券

莊筑豐 Unknown Date (has links)
連動式債券已成為目前市場上最熱門的投資工具,標榜著高受益的條款下,常隱含著投資人所不瞭解的風險,利用理論的模型套用在實務商品上,可以令人更清楚認識複雜化的金融衍生性商品。本文在Libor市場模型與Hull-White利率模型的架構下,利用數值方法評價分析最常見的兩種連動式債券-固定期限利率交換利差連動債券與信用連結債券。 Libor市場模型直接拿取市場上可觀察到的遠期Libor利率做為模型的標的,有良好配適目前利率期間結構的優點。利用此模型為出發,校準出波動度期間結構,以蒙地卡羅模擬法來評價固定期限利率交換利差連動債券。由評價結果可量化分析出連動式債券內含的選擇權與零息債券價值為何,探討發行商的發行策略與投資人的風險來源。 繼股權、利率連動式商品之後,未來金融商品的連動標的將進入信用風險的階段。以公司債的市場資料建立出一條信用風險曲線(Credit Curve),最能夠反映出當時市場上大多數人對於未來發生違約事件的預期。在假設利率市場風險和標的公司信用風險是獨立的前提下,將這條曲線和以Hull-White利率模型為基礎建立的利率三元樹與路徑函數結合,便可以適當地評價信用連結債券的價值。最後,求算債券內含的信用違約交換價值,對發行機構的策略與投資人的風險作分析。

結構型商品評價與分析-以雙重結構利率連動債及通貨膨脹連動信用債為例

廖韋綾 Unknown Date (has links)
市場上為了因應投資人的需求,推出來越來越多樣化的結構式產品。結構型商品雖然標榜保本、高配息、高預期報酬,但仍然依照產品結構與連動標的不同,而有相當的投資風險。所以投資人應做好基本功課與認知,才能在投資連動債時明哲保身。 基於上述的理由,本文希望可以透過對結構式債券的評價、分析,讓投資人更了解投資結構式債券所面臨的風險與報酬,避免投資人因為不了解結構式債券的特性而遭受損失,或是因為不了解結構式債券而降低了投資的意願。 個案一為雙重結構利率債券,採用的評價方式為:先利用無套利Hull and White利率模型建構與市場式一致的利率期間結構,再搭配路徑函數的方式展出每日的利率樹,經過轉換後就可根據條款倒推求算利率連動債券的價格。 個案二為通貨膨脹連動信用債券:先採用Duffie and Singleton的方式建構信用曲線,求出違約邊際機率後;再透過Monte Carlo的方式模擬消費者物價指數來計算每期配息。在已知每個節點的預期現金流量後,就可利用倒推的方式求解信用連動債券的價格。

我國大學圖書館網站網頁連結引用之研究 / The study on the sitatoin analysis of university library websites in Taiwan

方靜如 Unknown Date (has links)
本研究旨在應用網路計量法,尤其是網頁連引分析法,對我國大學圖書館網站網頁進行測量和分析。一方面、以EXtract URL蒐集大學圖書館網站網路資源之相關數據,並從國家/地區(top-level domain)、單位屬性(Second-level domain)、網域名稱(Domain Name)、一致性資源位址(URL)等四個網域層級,剖析我國大學圖書館網站所蒐錄之「網路資源」的數量、網站類型、網頁內容屬性等,從而比較各大學圖書館網站所連引網路資源的共通性與特殊性;另一方面,採用搜尋引擎A1taiSta檢索並分析這些大學圖書館網站綱頁在網網相連的虛擬世界中,為其他綱頁所連結引用的程度與情形,包括連引次數與網路影響係數的計算,以及連引網頁之語文,並透過跨時研究比較其在前後七個月的兩個時點上被連引情形的消長。 本研究所規範的「網路資源」範疇,乃依圖書館網站組織與呈現網路資源的方式與取向區別為三類,其中以「一般性網路資源」和「參性網路資源」居多,「專題性網路資源」則相對較少。研究結果發現39個大學圖書館網站中提供「網路資源」服務的佔有34個,共收錄了10,144筆網路資源,平均每個圖書館收錄298.35筆,其中靜宜大學圖書館以1,429筆奪得第一。實際上,這些網路資源來自於54個國家/地區網域;4,606個不同的綱域名稱;6,818個不同的網址。若將其網址依國家/地區網域做分析,我國(.tw)網域佔五成以上,而其中又有半數為學術網域所含括;居次者為美國,所佔將近四成,而商業網域又佔有其申四成;若依單位屬性網域做分析,以屬於學術網域的網路資源所佔達四成為最多,其中以我國與美國網域貢獻最多;屬於公司網域緊隨於後,佔有將近三成.,其申以美國與我國綱域貢獻最多。在被連引次數上,國內網站以被連引網頁次數累積達150次的中央研究院為最高,其次為教育部、行政院主計處、國家圖書館等網站;國外網站則以美國國家醫學圖書館與柏克萊數位圖書館SunSITE並列第一。大致上,可將我國大學圖書館網站所連引網路資源歸納為八類,被連引最多的類型是圖書資訊服務,其餘依次為政府機關、學術單位、研究機構、博物館/數位博物館、書店/網路書店、國際組織、其他等。" 外部連引可作為評估圖書館網站對外部網站的影響力之依據;而內部連引則反映了圖書館網站與校園網域內的其他網站的互動。本研究結果顯示,外部連引次數以成大、台大、央大等圖書館次數為領先;內部連引次數則以台大、交大、政大等圖書館居前。以連引數為分子,網頁數為分母所計算出的網路影響係數方面,所有大學圖書館網站的影響係數為0,33,亦即表示我國大學圖書館網站,平均每一個網頁被連引0.33次;外部連引的網路影響係數以逢甲、東華、中正等大學圖書館領先;內部連引的網路影響係數則以東華、南華、世新等大學圖書館居前。另外,在連引網頁的語文方面,我國大學圖書館網站被中文綱頁所連引的數量佔 93.57%;被英文綱頁所連引的數量佔9.46%,其餘語言則佔0、73%。 本研究建議圖書館應透過電腦軟體與人工定期檢閱連引節 點之有效性;並拓展專題性與特藏性網路資源的建置,以期建立各館之不可替代性的網路資源;同時深入連引網站內層之綱頁內容,以一個網頁或一個網頁片段作為一個連引單元,俾能強化其對使用者的實質效益。圖書館也能善用搜尋引擎以調查圖書館網站被內部和外部連引的情形,以自我評估圖書館網站與內、外部網域社群之間的互動和影響。另外,本土性的幾家中文搜尋引擎,加Openfind、Gais等,除應致力於擴展索引涵蓋的版圖興提升穩定性高的檢索結果外,還能豐富其相關檢索功能。 / The purpose of this study is to apply webometrics, especially sitation analysis, to examine and analyze thirty-nine university library websites in Taiwan. On one hand, the study utilized Extract URL to collect data aboutInternet resources of university library websites, and analyzed top-level DNS,second-level DNS, Domain Name, URL, respectively. The similarities and differences of the university library websites among each other were compared based on the analyses of number, types of websites and attributes of web pages of the "Internet resources". On the other hand, the study used AltaVista to retrieve and analyze the web pages of university library websites which interlinked by other web pages in the labyrinthine cyberspace. The Items measured included the numbers of total sitation, external sitation, internal sitation, and self-sitation, as well as languages of linking web pages.Furthermore, the investigation ran through two time spots across seven months to observe the changes of the sitations. The "Internet resources" appeared on the library website were organized into three categories: "general resources" and "reference resources", came out to be the majority, whereas the "specific resources" was the minority. The study found that thirty-four out of thirty-nine university library websites had provided service of Internet resources, and the items of Internet resources were 10,144 in total, from 54 different top-level DNS, 4,606 different Domain Name, and 6,818 different URLs. The average number of Internet resources per library website was 298.35. The Providence University Library earned the first. The analysis of top-level domain showed that the Taiwan was in the majority, and USA got the second. The analysis of second-level domain also found that academic domain earned the first, and business domain was the second. TheInternet resources can be grouped into eight types: library and information services was the first, and the other included government institutions, academic organizations,reseah institutes, museum/digital museum, bookstores/Internet bookstores, international organizations and others. External sitation is seen as an indicator of significance and influence of a site for external websites, and internal sitation may respond interaction and effect between a university library website and other websites in web domain of campus. The findings of study revealed that the external sitations ofNational Cheng Kung Universe Library, National Taiwan University Library and National Central University Library were the first group; and the internal sitations of National Taiwan University Library, National Chengchi University Library and National Chiao Tung University Library were the top group.Besides, the Web Impact Factor of university libraries in Taiwan was 0.33. The number of Chinese web pages that linked to university library websites turned out to be 93.57% whereas the number of English web pages was only 9.46%.The number of web pages linked in other language was only 0.73%. Finally, the study suggested that libraries should better use computer software and human aids to check the validity of hyperlinks; and devote library staff's energies into the development of specific Internet resources; further,libraries should link the content of web pages of websites in depth. Libraries should also examine various sitations of self library website to evaluate the interaction and influence of the library website with inside and outside web domain. Local search engines, for instance, Openfind and Gais, should strengthen the scope of index, enhance the stability of searching, and improve the retrieval functions in the filture.

模板屬性對瀏覽行為的影響-以線上遊戲為例 / The Impact of Template Attributes to User’s Behavior-Take Online Game as an Example

陳妍樺, Chen, Yen Hua Unknown Date (has links)
面對大量習慣用嘗試錯誤方式去學習使用複雜線上遊戲功能的使用者,如果沒有一個好的網頁佈局設計,會妨礙讓使用者易於上手。本研究試圖綜合以往在電腦學習認知方面的模板比對理論、CoLiDeS Model、及資訊氣味等相關研究,增強對線上遊戲介面設計的了解。本研究設計一個線上遊戲介面認知的實驗,用「仙劍Online」多人線上遊戲的介面為實驗工具,運用眼動儀去觀察受試者的瀏覽行為。「功能的群組位置」(Location)與圖像(Icon)皆為介面設計的重要因素;這兩項因素可能會影響受試者對任務難易的知覺判斷與瀏覽行為的Pattern。這些差異會顯示在任務的「間隔多久時間看到正確區域位置」、「凝視次數」、「凝視正確區域佔全部的比例」、任務的「完成率」與任務的「使用時間」等資料上。經過本研究驗證可以明確的知道「功能的群組位置」(Location)與圖像(Icon)何者為設計者首要考量之因素,在學術上能加強對CoLiDeS Model的了解,提出兩階段修正的認知模式;在實務上幫助介面設計師進行更有效的頁面設計和實用的建議。 / A large amount of users practice the trial and error approach to learn to use complicated online games. This leads to low user perception of "easy to use" when the game lacks good webpage layout design. This study attempts to integrate previous studies on cognitive learning through computer including Template Matching, Information Scent, and Comprehension-based Linked model of Deliberate Search Model ( CoLiDes Model), to enhance the understanding on online game interface design. A cognitive experiment of online game interface was designed utilizing the multiplayer simulation game "Chinese Paladin Online" in an attempt to observe and record user’s browsing behaviors through the eye tracker. "Location of functional group " and "Icon" are important factor of interface design and affect user’s browse behavior pattern . These differences will appear in "Time spent", "Accuracy", "Frequency of fixation ", “ and "Time spent before first fixation on the correct position" of the tasks. We expect the results extended the CoLiDeS Model, enhanced understanding of the interface layout user cognition, and provided fruitful suggestions in how to further design on effective WebPages.
