The proliferation of digital media use in this protest, makes it a significant case study in regards to finding the complex media networks of tech-savvy activists and mainstream media at work in recent political protests. To answer the complex nature of this network, this paper employs Actor Network Theory (ANT) as a framework to depict the evolving media network of contemporary political protests in Taiwan through first-hand accounts of alternative media activists and mainstream journalists. This research conducts a set of qualitative interviews with heterogenous actors who participated in the Sunflower Movement. Additional data is collected from online documents of the event. In the end, the research seeks to answer the following questions: How do new and old media form links through technology and digital tools in modern political protest? What is the nature of the associations formed and how do the associations impact the existing news ecology in political protests? Further providing an empirical account of transforming protest media networks in action in a political protest context.

綠色物流專案之淨現值:太陽能板安裝之個案研究 / Net present value for green logistics projects: a case study on solar panels installation

林文龍, Pla, Adrien Unknown Date (has links)
The gravity of the Global Warming consequences force us to face the issue and try the best to mitigate its effects. Green Logistics practices, and especially the case of a Solar Panels Installation on a warehouse or plant’s roof, are studied in this article as solutions to reduce the economic, social and environmental casualties. The Net Present Value (NPV) Model in this paper and its results analysis show that project duration, Carbon Tax, initial energy price and its increasing rate are all positively related to the NPV Value. A high discount rate will, however, turn the NPV negative, thus raising the need of financing help for Green Logistics projects.

<<聯合報>>野百合與太陽花學運的語藝視野分析 / The Rhetorical Vision of Wild Lily Student Movement and Sunflower Student Movement in the United Daily News.

曾淑芬 Unknown Date (has links)
新聞報導是一種語藝的行動或一種說服之過程,也是一種真實的再現,透過不斷的傳播,建構出團體成員對外在世界的共同認知,逐漸成為閱聽人的共同印象。以社會運動來說,新聞工作者往往認為「衝突、對抗、造勢」等戲劇性效果,最具新聞價值,也最能代表社運,因此,媒體建構了社運,同時建構了人們對社運的印象。而以學生為主體的社會運動,因角色的轉換與社會的想像,使得媒體刻意在報導中多了些「保護」與「憐惜」,易產生與其它社會運動不同的報導取徑。   本研究以《聯合報》的野百合學運和太陽花學運的新聞報導作為研究對象,透過「幻想主題分析」的研究架構,輔以外在分析,探討單一媒體建構學運的語藝視野是否會隨著時代變遷而有所變化?   研究發現,在《聯合報》語藝建構下,兩代學運呈現迥然不同的語藝視野,野百合學運的語藝視野為「憲政改革眾望所歸」和「民主自由難能可貴」;太陽花學運的語藝視野為「朝野惡鬥國會失能」和「民主之恥民主鬧劇」,並發現學運期間的讀者投書,具明顯的覆誦現象,形成一致的語藝社群,不僅如此,本研究同時驗證了單一媒體在建構不同世代學運的語藝視野,並不會全然產生相同的觀看視角與報導取徑。

溫室氣體排放管制趨勢下-台灣石化產業之發展策略 / The development strategies of petrochemical industry in Taiwan-under the trend of severe GHG emission control

蔡錫津 Unknown Date (has links)
近年來,隨著能源價格不斷飆漲以及溫室氣體大量排放造成的氣候異常變化,引起世界各國對於提高能源使用效率與加強溫室氣體排放管制的重視。溫室氣體大多由化石燃料燃燒所產生。因此,一般被視為能耗較高的發電、鋼鐵、水泥以及石化等產業,遂成為眾所矚目而被要求加強溫室氣體排放管制的主要產業。未來的產業發展規劃,必需兼顧經濟與環保,否則必將被世界潮流所淹沒。 因應全球溫室氣體排放管制趨勢,就台灣經濟發展面、財政建設面、環境永續經營面等層面考量分析,現階段石化產業之發展應對產業競爭力及環境保護做更多且更審慎的考量。於產業競爭力部分,建議中油開放民營,並運用部份釋股取得的資金,一方面引進先進的製程技術及進行設備更新,提升企業競爭力;另一方面整合國內仰賴台灣中油公司供料且在各產品領域擁有數十年營運經驗的中下游業者,建構泛中油體系的石化經營團隊。如此泛中油體系與國內另一石化產品鏈已相當完整的台塑體系,形成兩大石化體系,互為良性競爭。於環境保護方面,則建議我國應終止國光石化投資案,降低溫室氣體排放量,並藉提升廠商製程效率減少能耗,如此將使經濟發展及環境保護得以兼顧,亦達成原興建國光計畫之目的。 而未來台灣石化產業發展策略,技術發展需長期向下扎根,產品則朝高值化、精緻化發展,開發低能耗、低污染之替代能源,提升產品的附加價值,並將大宗石化耗能的產品移往海外能源低廉的地區,持續提升產業競爭力,並達成溫室氣體減少排放為目標。如是,台灣在環境保護日益重視之趨勢下,石化產業也得以永續發展。 / The high energy cost and the unusual climate change due to increasing green house gases(GHG)emission in recent years have attracted the global attentions and called for improvement of energy utilization efficiency and enhancement of GHG emission control. GHG are mostly produced by the combustion of fossil fuels. And the higher energy consumption industries such as power generation, steel, cement and petrochemical industries are thus strongly requested to reduce GHG emission. Economic development and environmental protection both are needed to be equally evaluated in the planning of future industry development. Taking petrochemical industry as an example, many of its mid-stream and down-stream products have become an unseparable part and of our daily life. In Taiwan, it has been over half century since the establishment of petrochemical industry, and now become top 10 petrochemical production countries in the world. The production value of petrochemical-related industries are very close to 4 trillion NT dollars, about 30% of total production value of domestic manufacturing sectors. Petrochemical industry and electronic industry are the two strong arms in supporting national economic growth. As a very important industry in Taiwan, however, the intensity of its GHG emission is only next to steel industry. The significant technology improvement in petrochemical industry has been achieved since the installation of the existing refinery, naphtha crackers and many petrochemical mid-stream production plants in Taiwan. It is well recognized that the GHG emission will be greatly reduced if the advanced technologies are introduced and the old facilities are revamped. Therefore, the writer would like to address a different approach toward KuoKuang Petrochemical Project which the government is giving an impetus to its execution. Here the writer would propose Taiwan CPC company, the state-owned petroleum company and the leader of Kuokuang Petrochemical Project, to become privatized after asset re-evaluation and collect some government capital from privatization through issuance of part of its shares to the open market. The capital thus collected can be used for enterprise reform. The important items of the enterprise reform include but not limited to introduction of the advanced technologies, revamping of existing facilities and establishment of a new well-integrated petrochemical conglomerate through mutual investment between Taiwan CPC and the mid-stream companies that rely raw material supplies from Taiwan CPC. From viewpoints of both economy and environment, government policy of implementation of KuoKuang Petrochemical Project is worthy for reconsideration. Formation of a CPC-lead petrochemical conglomerate would also benefit the current petrochemical companies that rely on raw material supplies from Taiwan CPC as their operation efficiencies would improved from business intergration. The newly formed conglomerate would be more powerful in further business development and more competitive in world market. They would have more resources to explore their potential in advanced technology development, in new business fields such as biomass energy, solar energy and so on. The CPC-lead petrochemical conglomerate would be able to enchance its competitiveness to another domestic petrochemical giant, Taiwan Formosa Group, and other petrochemical giants in the global market.

兩岸太陽能光電廠商競合策略研究 / A case study for cross-strait photovoltaic interfirm co-opetition strategy

王羚卉 Unknown Date (has links)
近年來,環境汙染、能源危機等議題,使世界各國莫不開始重視環境永續經營之課題。目前被認為具發展潛力之替代能源包括太陽能、風力、地熱、水力、生質能等,其中,由於太陽能為取之不盡、用之不竭的循環再生能源,具無汙染、發展歷史悠久、取得來源穩定、發電成本逐年下降等優勢,因此,各國政府皆致力於太陽能光電產業之發展與推動。 根據統計,太陽能光電產業產品製造重心在2008年金融風暴後,快速往亞洲地區移動,產量增加最快的地區為中國和臺灣,兩岸因各自不同的地理環境、發展條件、政府政策等因素,促使相關產品在全球市場佔有率持續增加。2009 年全球太陽能電池產量為9.34GW,其中,中國與台灣佔全球總產量的49%(中國38%、台灣11%),可見兩岸同時共享全球太陽能光電市場,亦共同競爭全球再生能源產業版圖。 本研究由廠商角度出發,針對兩岸太陽能光電產業競爭與合作策略進行多面向分析研究。首先透過Porter (1980, 1990)五力分析與鑽石模型,對兩岸太陽能光電產業進行探討,並以廠商層次之資源基礎與交易成本等理論,瞭解個案廠商的交易成本與交易價值,同時探討國家和產業因素是否在廠商合作或不合作決策間形成調節效果。本研究發現,面對中國廠商,不同價值鏈階段的台灣廠商需選擇不同的競爭或合作策略,垂直整合並非台灣太陽能光電廠商首選之發展策略。同時,基於資源與能力的互補性可發現,兩岸同價值鏈階段廠商呈相互競爭狀態,廠商合作動機低,而兩岸不同價值鏈階段廠商的合作動機則高。在合作方式方面,則因台灣廠商的目的性差異,主要分作長短期契約和合資兩種方式。此外,本研究亦發現國家條件,如生產要素互補性與政府政策,以及產業發展現況將帶動兩岸廠商建立合作關係的可能性。 / Due to increasingly environmental issues such as pollution or energy crisis, people begin to regard environmental sustainability as an important topic in recent years. There are several kinds of potential substitute energy, including solar, wind, geothermal, water power, biomass energy, etc. Solar energy is one of important substitute energies because of its pollution-free characteristics, stability and decreasing cost trend. Therefore, the governments are committed to develop and promote the solar photovoltaic industry. According to statistics, the production area of photovoltaic products has been moved quickly from Europe to Asia after the financial crisis in 2008. The two of the fastest growing areas are China and Taiwan. Due to geographical environment, development conditions, government policies and other industrial factors, photovoltaic products from China and Taiwan continue to increase in the global market share. For instance, China and Taiwan accounted for 49% (or 93.4GW) of the worldwide solar cell production (38% in China, 11% in Taiwan) in 2009. It is obvious that China and Taiwan are competing the global photovoltaic market share. Based on five forces model, diamond model, transaction cost theory and resource-based view, this study provides a multi-strategic analysis of co-opetition in the cross-strait photovoltaic industry. By collecting secondary data and conducing case study, I complete a serious of systematic analysis and results with the grounded theory approach.

台灣光電企業跨足綠能整合之策略布局 / The transformation strategy of Taiwan's optoelectronic company to the green energy integration industry

魏明皓, Wei, Ming Hao Unknown Date (has links)
台灣光電產業為近年來台灣經濟成長的最佳動力來源之一,截至2010年,台灣光電總產值已經突破新台幣2兆元。其中以LED、顯示面板、太陽能電池模組等貢獻最多,帶給台灣大量的就業機會,並創造出全球第一的產值。然而,台灣光電大廠以往的經營模式大都以OEM/ODM為主,製造代工屬微笑曲線價值最低的中間區域,因此企業不斷找尋轉型的機會。近年來因能源耗竭隱憂,綠能產業蔚為未來科技革命的新主流,如太陽能發電、風力發電、LED照明、電動車等,為台灣光電大廠創造新的契機。幾間光電領導大廠紛紛跨入綠能產業,除了研發製造端,也開始嘗試挑戰下游的系統整合與行銷通路,尤其以太陽能發電系統為主。面對下游不熟悉的領域,以及眾多的綠能廠商競爭對手,光電企業必須從自身核心能耐出發,找尋最佳切入點,並靈活運用相關資源,與事業夥伴密切合作,方能找到自己的定位,建立獨特競爭優勢。 本研究從光電企業跨足綠能產業的先後整體性策略布局進行分析比較,並由顧客價值與企業核心能力的角度出發,深入探討面對綠能產業下游的新事業之組織設計、營運模式、關鍵資源、關鍵流程等。本研究建議台灣光電廠商面對市場白地時,應打破傳統製造思維,以創新商業模式進行在地化資源整合,進而建立行銷通路,打造自有品牌。並且建構良好的學習交流管道,讓新事業在下游的經營管理經驗帶回企業。 / Recently, the optoelectronic industry becomes one of the driving forces of economic growth in Taiwan. Until 2010, the output value of optoelectronic industry was over 2000 billion NTD, creating many employment opportunities. The optoelectronic industry in Taiwan is accounted for the largest output value in the world, especially in sectors such as LED, photovoltaic panels, solar cell and solar modules. However, a lot of optoelectronic companies in Taiwan are OEM/ODM based. They capture the lowest value in the supply chain. Hence, many companies are eager to seize the opportunity to implement transformation strategy. Nowadays, due to energy depletion issue, more and more people care about the popularized green energy industry, include solar power, wind power, LED lighting, electric cars and so on. This condition states good foundation for optoelectronic companies in Taiwan to perform transformation strategy. Some leading companies started to cross boundaries into the green energy industry, especially focusing on manufacturing and system integration of solar power system. Facing the unfamiliar downstream business and existing green energy competitors, optoelectronic companies should start with own core capability to find the best point of entry while entering the whole new industry. They need to integrate local resources and cooperate with business partners, finding their unique position and to build up their own competitive advantage. This study analyzes a comprehensive strategy framework for optoelectronic companies in Taiwan crossing over to the green energy industry. First thing ahead, the company should start with its own core capability and consumer value, developing new business model, organization structure, key resources and key process of the new field. The conclusion of this research suggests that optoelectronic companies in Taiwan should forgo its old ways of manufacturing thinking, and operate with innovative business model to integrate the localized resources, establish its own marketing channel, create its own brand, and construct good learning process that can bring downstream experience into the organization when operating in the new industry.
