制度驅動的中國能源戰略與石油安全 / China's institution-driven energy strategy and oil security

姚源明, Yao, Yuanming Alvin Unknown Date (has links)
本文要旨在回答中國大陸的能源戰略是如何形成,並探討此一戰略如何影響中國大陸的石油安全。本文主從歷史制度主義的觀點主張中國能源體制是決定中國的石油戰略最重要的因素。解釋中國的能源部門在經濟改革與國際化的內、外部環境下,產生制度變遷,進而形成不同時期的石油戰略。在回答中國大陸日益龐大的石油需求與進口石油依賴,使得政府制訂出提升能源使用效率、節約能源、能源多元化與確保海外石油供應 但由於中國為保護國有石油企業的壟斷角色,對於「迎進來」的市場進入條件設下許多條件限制,對外又採取積極的石油外交,使得國際社會對中國產生重商主義與保護主義的疑慮。 中國的能源部門自1980年以來已經歷幾個階段的改革,第一階段是從1982年至1987年,強調要計畫經濟為主、市場力量為輔的能源制度改革;第二階段是從1988至1992年,重點在於國有企業的改革,鼓勵國有企業集團化;第三階段是從1993至1997年,重點在政企分離,並把配置資源的基礎性職能轉移給市場;第四階段是從1998至2002年,重點在加強國有資產的監管與國有企業經營,並初步建立宏觀能源調控體系;第五階段則是自2003年以降,主要的改革目標在建立跨部門的能源協調機制與對外的競爭力。 本文但由於「漸進主義」式的制度變遷使得能源部門體制改革仍存在許多問題,諸如能源部門分散、能源監管部門眾多、國家安全思維與既得利益等,使得政府部門考量其能源安全時,政府干預仍多於市場思維,即便自改革開放以來國家能力已不斷衰退。但在能源辦與發改委能源局的人力有限以及能源部門缺乏效率的情形下,擁有龐大資源的三大國有石油企業(中石油、中石化、中海油)無疑「挾持」政府的決策,例如理論上中央政府可完全控制與審核國有企業的海外投資,但實際國有企業通常是在海外投案案定局後才通知發改委與國務院。中國的能源決策中的缺乏效率常來自於既得利益者的把持,而不願在整體的政治與經濟政策上肩負起更多的政策責任,例如中央政府與國企對於戰備儲油到底由誰出資的內部爭論。 未來中國的能源戰略會持續採取「迎進來、走出去」的方向;近年來政府試圖改革其能源決策程序,透過建立跨部會的決策協調機制試圖重奪能源決策的主導性,因此於2005年5月正式成立「能源領導小組」,並積極透入政府能源白皮書與能源相關法案的草擬,政府的舉動等於是將能源政策的制訂再度「中央化」。未來中國能源戰略的最大挑戰仍來自於能源體制能否深化改革,並且制訂出對外、對內策略一致的能源戰略,以因應中國未來的石油需求以及消減國際社會的疑慮。 / The new facet of global oil politics and China’s surging oil demand have forced the Chinese government and state-owned enterprises to secure foreign oil supplies and to implement energy efficiency. However, systemic level or state-centered theories have provided limited theoretic orientation to explain China’s state behaviors and foreign behavior. It is essential to explore China’s energy institution and energy strategy behind its quest for oil security. That is, China’s foreign strategy should be put into broader context of China’s institutional evolution and domestic/foreign energy policy-making process. This research applies historical institutionalism to look at history evolution of China’s energy institution and energy strategy (especially oil strategy). Chinese energy institution has experienced four main stages of institutional evolution since 1980s. The main themes of four stages have emphasized different administrative, institutional, and energy goals. Meanwhile, institutional critical junctures and feedbacks (formation and reproduction) also have existed in every stage. The first phrase (1980-1992) emphasized how to integrate market forces into China’s bureaucratic institution with socialist characteristics and the market oriented reforms faced several institutional challenges due to necessity of central planning; the second phrase (1993-1997) was characterized by slight and limited institutional restructuring within the energy sector because market force did not gain political support from the leadership. The Chinese government established both the State Energy Commission (SEC) (1980-82) and the Ministry of Energy (MOE) (1988-93) in the wake of acute energy shortages to re-centralize authority over the energy sector. However, neither institution could effectively coordinate and implement energy policy, partly because they could not overcome the vested interests in sectional industries. The third phrase (1998-2002) was characterized by radical institutional reforms on conglomerating SOEs and delimiting administrative power. The National Development and Reform Commission (NDRC) along with the Energy Bureau within it have taken over full governmental regulatory and public sector responsibility from SOEs. However, NDRC functions not as powerful as SOEs do. Therefore, the fourth phrase (2003 until now) then put attention on the establishment of a super-ministerial interagency, revivification of administrative power, and emphasis of foreign competitiveness. The establishment of State Energy Leading Group (SELG) aims at regaining strong central authority and to correcting turbulent oil strategies made on a base of institutional constraints. Above all, China’s institutional evolution is characteristic of state-regulated marketization, limited property right reforms, strategic preference, and departmentalism in China’s energy sector since 1980s. The institutional evolution has constrained China’s energy institution from planning a long-term national energy strategy. China’s energy sector continuously confirms institutional formation by the support of highest leadership and mainstream ideology, and confirms institutional reproduction between the directive and liberal forces, between the government and market forces. Meanwhile, international responses to China’s hunting behaviors are to play either a conductive role in impelling China’s institutional reforms and in adjusting its foreign behaviors. To prevent serious energy competition and to enhance international cooperation, China has shown its willingness to communicate with other nations on oil issues. However, China also needs to show its determination to implement domestic demand-side measures and a market approach instead of implementing protectionist “welcome-in” and aggressive “going out” policies. Ongoing institutional reforms still determines whether the China’s energy institution will ensure the country’s energy security. In the short term, the establishment of the central authority in the energy sector will improve departmental coordination and policy persistance. However, in the long term, China’s ongoing institional reforms need to integrate more market forces, proceed property right reforms, and reshape relationship between the government and market. Without deeper institutional reforms, energy bureaucrats and SOEs would be dragged into institutional process of formation and reproduction but gain limited results in meeting China’s oil security.

臺灣生質燃料產業發展策略之研究 / Development Strategies in Biofuel Industry:Taiwan’s Experience

張宗顯, Chang,Tsung Hsien Unknown Date (has links)
石化能源逐漸耗竭引人關注,再加上「京都議定書」對溫室氣體排放之全球性管制,促使世界各國重視各種新能源與替代性能源,並積極投入應用與研究開發。生質燃料已成為全球許多國家的戰略性資源,其發展除可開發自產綠色能源,提高能源自主比例,並能結合能源、農業、環保、產業等共同發展。面對全球生質燃料產業急速成長,台灣自不能自外於節能減碳的永續發展趨勢。 為驗證政府推動生質燃料政策的環境條件及業界投入狀況,本研究以次級資料分析方法進行國內、外之發展現況及趨勢分析;透過學者、專家、政府業務執行主管及業者之深度訪談,藉由訪談之資料歸納國內發展情形,對照現有生質燃料政策推動目標之發展模式,並以五力分析架構及SWOT評估方法評估生質燃料產業發展之競爭力。 本研究的主要發現包括:1.影響我國生質燃料的發展,最主要的關鍵要素是料源成本、價格補貼及市場保證;2.在推廣生質燃料的策略作法上,絕大多數主張應依政府政策規劃目標循序漸進推動;3.業者在發展生質燃料過程中,面臨最大的困難在於政策的不確定及原料的掌握不足;4.產業發展初期仍應以國內產製優先,不足部分再開放進口;5.生質柴油料源中,目前以廢食用油最具價格競爭力,麻瘋果油次之,藻類則是長期看好的料源。生質酒精部分,依國內廠商最可行技術而言,以甘蔗酒精較具價格競爭力,狼尾草居次,纖維素作物則是長期看好者。6.現階段的政策目標,在生質柴油部分的推廣比例仍以B2為佳,生質酒精則以E3為國產料原的最大量。長期來看,生質燃料產業的擴展,一定要以非糧食作物為優先,關鍵環節在於纖維酒精技術及藻類開發技術有突破,推廣比例及市場規模才有再擴張的空間。 就研究分析所得,提供下述政策建議:1、政府需訂定明確的政策目標;2.成立再生能源國家型計畫,加速推動生質燃料發展;3.政府率先投資第二代生質燃料產業;4.需建構生質燃料永續發展的制度性設計;5.確立以本國產製為優先之政策宣示;6.強化節能減碳教育宣導,讓消費者建立信心並接受。在業界策略上建議:1.必須提升料源掌握度與開發多元料源,並降低生產成本;2.業者須加強與通路商籌組供油策略聯盟;3.生質酒精業者可採合資或合作生產方式切入市場,取得先占地位;4.積極參與第二代生質燃料的研發與技術銜接。 / Petrochemical energy shortage is an issue that has been gradually gaining attention. Global regulation of greenhouse gases emission set by the Kyoto Protocol has also called attention to new and alternative energy sources, as well as the active involvement of individual countries in new energy application and research development. Biofuel has now become a strategic resource in many countries. Additional development of alternative energy can not only help increase the amount of domestic green energy and its ratio to traditional energy, synergy is also created causing the equal development of energy, agriculture, environmental production, and industrial growth. In face of the rapid growth of the biofuel industry worldwide, Taiwan must not exclude itself from the trend of sustainable development in energy conservation and CO2 reduction. To access the conditions of government policy in biofuel promotion and industry involvement, this study used secondary data analysis methods to analyze the current trend and status of national and international development. Through information gathered from in-depth interviews with academics, experts, government executives, and industry members, current domestic developments are compared to existing models of biofuel policy, promotion, and objectives. The competitiveness of biofuel industry development is further evaluated using SWOT assessment and Five Power Analysis. The main findings of this study include the following: 1) The key elements affecting national biofuel development are raw material costs, price subsidies, and market guarantees. 2) In biofuel promotion strategies, a vast majority should be made gradually and according to government policy planning objectives. 3) In biofuel development, the biggest challenges the industry faces are policy uncertainties and the lack of raw materials. 4) In initial industry development, domestic production should be a priority, allowing imports only when in demand. 5) In raw materials for bio-diesel, recycled oils are currently the most competitive in value, followed by Jatropha oil, while algae is seen as having long-term potential. According to the most viable technology offered by domestic manufacturers, sugarcane ethanol is the most competitive in value for bio-ethanol, followed by Chinese Pennisetum, while agricultural waste is seen as having long-term potential. 6) In the current stage of policy objectives, B2 is still more adequate in the promotion of bio-diesel, and E3 is the main domestic raw material for bio-ethanol. In the expansion of biofuel industry in the long run, priority must be given to non staple crops, while the key lies in cellulosic ethanol and algae oil development technology. Only then can there be room for further expansion in promotional proportion and market scale. The following policy recommendations are provided based on analysis of the study: 1) Clear policy goals must be set by the government. 2) Establish nation-wide plans for renewable energy, and accelerate the promotion of biofuel development. 3) Government must take initiatives in second-generation feedstock investments. 4) A systematic design must be built for the sustainable development of biofuel. 5) Policy declarations must be made to ensure the priority of domestic production. 6) Strengthen education in energy conservation and CO2 reduction, and build consumer confidence and acceptance. Recommendations for industry strategies: 1) It is essential to increase control of raw materials, develop multi-source materials, and lower production costs. 2) The industry must strengthen its strategic alliances with distributor in oil supply. 3) The biofuel industry may partake in joint ventures or cooperative efforts to get a head start when entering the market. 4) Actively participate in the research and development and technology adaptation of second-generation feedstock.

自律公約與公平交易法 / A study on Self-Regulation in Competition Law

林柏男, Lin, Po Nan Unknown Date (has links)
本文所稱之「自律公約」,係指經濟上、實質上之自律公約,意指事業間相互約束經濟活動,從事正當競爭之自律公約,如不涉競爭參數,僅係單純之道德呼籲,則非本文所討論之自律公約。符合上開要件,縱不名為「自律公約」,也為本文所討論之對象。   近年台灣社會邁向管制開放,同時公平交易委員會功能是否發揮預期功能,相關討論為數不少。競爭的基本理念是相信市場有自我治癒之功能,如果市場有自我治癒的能力,政府是否還有積極介入之必要?如果市場功能不彰,政府究竟應採取逕行介入之思考,或培養市場自我治癒之能力?如果市場自我治癒之功能彰顯,相對而言,政府行政任務即相對減輕,亦減少政府過多之干預。因此本文希望藉由文獻分析方式,參酌外國立法例、分析事業遵循自律公約之誘因,以提高自律公約之可行性,並期將來能建立自律公約制度,由事業自行負起監督之責,使公平交易委員會之行政任務得以簡輕,使事業不為不公平競爭,達到促進競爭之目的。 / This thesis focus on the topic of self-regulation issues in competition law. By observing Germany, Japan and US how to carry out self-regulation , we can know the value of self-regulation. This article also discuss whether self-regulation agaist Competition Law. In pursuit of successful self-regulation , it’s necessary to know what’s industry’s incentive to obey slef-regulation and self-regulation how to work smooth. Successful self-regulation can ease the burden of government and improve the effect of market, so it’s expected self-regulation comes ture.

影響資訊系統開發團隊集體創意效能之關鍵因素

鄭秀華 Unknown Date (has links)
近年來,許多公司面臨需要透過資訊科技來獲取競爭優勢。各產業對於資訊系統的要求越來愈多,促使資訊系統的開發工作越加複雜,而使得成功完成資訊系統的開發變的日益困難。 軟體工程協會指出軟體能力成熟度整合模式(Capability Maturity Model Integration, CMMI)強調軟體開發需要追求開發程序的改善與程序的最佳化。透過程序的改善以降低軟體開發專案失敗的機率。根據創意的定義,資訊系統開發程序的改善是團隊創意的表現。 目前少有研究從創意的觀點探討資訊系統開發程序的改善。根據社會認知理論指出效能信念是解釋行為/產出的關鍵元素。學者們也證明創意自我效能對於創意的重要性。到目前為止,效能與創意的連結僅限於個人層次的研究。因此,本研究將以資訊系統開發程序改善為研究情境,進行集體效能與創意文獻的連結,提出資訊系統開發團隊集體創意效能之概念,並探討集體創意效能的前置因素與了解干擾集體創意效能形成的因素。 本研究採用部分最小平方法 (Partial Least Squares),分析98組開發資訊系統的學生團隊與61組開發資訊系統的業界團隊資料,以驗證研究模型。結果指出在學生團隊方面,團隊知識程度、成就動機、團隊知識整合能力會正向影響集體創意效能的形成;團隊互動程度會干擾團隊知識程度與集體創意效能的關係、專案複雜度會干擾團隊知識程度與集體創意效能的關係以及干擾團隊知識整合能力與集體創意效能的關係。在業界團隊方面,團隊知識程度、成就動機、團隊知識整合能力會正向影響集體創意效能的形成;團隊互動程度會干擾團隊知識程度與集體創意效能的關係、專案複雜度會干擾團隊知識程度與集體創意效能的關係、成就動機與集體創意效能的關係以及團隊知識整合能力與集體創意效能的關係。此外,本研究亦探討在不同專案複雜度的情境中,影響集體創意效能之前置因素。 / Numerous companies have recently employed information systems to obtain a competitive edge. The demand for many new and different information system (IS) applications has increased the scope and complexity of IS developing. Developing successful IS projects became difficult. Software Engineering Institute proposed Capability Maturity Model Integration (CMMI) that emphasized process optimization of software development. The improvement in software process can reduce the probability failure in development software. According to the definition of creativity, the improvement in software process is team creativity. However, there are few studies which discuss the issues about systems development process improvement from creative perspective. According to the social cognitive theory, efficacy is a key factor for interpreting behavior/products. Scholars demonstrated that creative self-efficacy is important to creativity. Previous researchers which studied the potential link between efficacy and creativity are focus on individual level. Thus, this study combined the literatures of collective efficacy and team creativity to propose a new construct (Collective creative efficacy, CCE) for information systems development teams, and explore the influences and moderators for CCE. 98 student project teams and 61 industry project teams are surveyed. Partial least squares (PLS) results demonstrate that team knowledge, achievement motivation and knowledge integration ability positively influenced CCE, team interaction positively moderated the relationships between team knowledge and CCE, and project complexity negatively moderated the relationships between team knowledge and CCE, and the relationships between knowledge integration capability and CCE in both samples. Project complexity positively moderated the relationships between achievement motivation and CCE in the model of industry project teams. An attempt is also made to understand the antecedents of CCE in different project complexity.

國會功能運作之研究(從法制規範與實務操作談起) / The Research of the Cogress Function

洪莎嫚, Hung, Sha-Man Unknown Date (has links)
過去立法院常被譏為行政院的橡皮圖章,但隨著國內民主政治的快速發展,立法院已成為我國當前最重要的政治舞台,不管是各政黨或是政治人物,對於在立法院合議制度下,所形成的權力分享與利益分配,都有莫大的關注與興趣。再者,立法院職權之行使攸關人民生活財產的維護,在民主化的過程裡,代表民意的立法院,更背負著民眾的高度期待。因此,研究立法院之監督功能,對立法與行政之間的互動關係做一明確的界定與釐清,將有助於了解我國民主政治的建立與實踐民主化的進程。 本研究旨在探討立法院之監督功能,也因此擬先介紹民主國家國會監督概念,針對「監督」一詞,加以界定並分析其理論基礎。再針對各國憲政發展之比較,來了解何以要研究我國立法院監督功能,並從我國民主發展過程中,探討立法院扮演監督功能的意義與角色,最後試圖從法制規範層次與實務操作層次上,找尋出我國立法院所具有的監督效果,以達到探究其監督功能之目的。 從萬年國會到國會全面改選,乃至目前歷經六次修憲以來,我國國會體制逐漸落實立法院真正成為全國最高立法機關之制度設計,不過立法權如何有效落實其監督制衡行政權的功能,除了從靜態的憲法條文賦予的職權來分析,還必須透過動態的立法權行使過程加以探討。因此,本文先從民主憲政原理中的監督背景及其概念,假設我國在國會全面改選後,雖然行政部門過去的主導力量甚強,但立法權仍能發揮其監督行政權之功能,以立法院所行使的職權是否具有監督功能來分析,並觀察出立法院非制度面部分,具有的實際監督功能之機制,最後做出結論與提出建議。 本文分成六個部分。第一章緒論,介紹本論文研究背景、研究目的、概念界定、研究架構設定、文獻回顧、研究方法及研究範圍與限制;第二章國會監督功能之理論基礎,從形成國會的民主概念破題,來介紹國會監督功能之背景、意義、基礎、技術,以了解民主國家之國會監督功能;第三章我國立法院監督功能之介紹,從我國立法院形成之背景,來介紹立法院監督功能之背景、意義、基礎、技術,以呼應第二章;第四章法制規範層次之監督功能分析,是以監督對象為基礎來分析立法院的監督功能,文中將監督對象分成對人如同意權、彈劾權等;對機關如預算權的監督;對政策如法案權,再放置到四個重要民主政治概念(權力分立、代議政治、有限政府、權力制衡)中來檢驗,以了解其法源依據、規範作用及實質影響;第五章實務操作層次之監督功能分析,將提出具有實際運作而無法在法制層次探討如議事杯葛、政黨協商等非正式制度面之監督功能,從實務操作層次中,去探討其實質影響。第六章結論,提出研究過程中所得到之發現,及希冀提供後進研究者之建議。

共同基金績效評估方法---文獻探討與實證主題研究 / Methods of Mutual Fund Performance Evaluation

黃鴻文, Huang, Hung-wen Unknown Date (has links)
台灣股市正走向法人時代,共同基金的重要性無庸置疑。可是台灣的共同基金市場存在著「市場封閉」、「資訊不公開」、「透明度不足」的問題,使得一般投資人在選擇基金時顯得無所適從。近來基金績效評估的研究逐漸受到重視,但是普遍未對評估方法的本身及方法間的演變過程有所了解,本研究藉由對各評估方法的深入探討及實證主題的層層闡釋,來找出一套評估方法的適用規則。 以下是歸納的研究過程與結論﹕(一)評估整體績效的各種方法﹕一般來說,若是投資人投資於多個基金,以Treynor指標來評估共同基金的績效比較合適。若投資人將其資金全部投入單一基金,則Sharpe指標原則上較能代表共同基金的營運績效。若希望與大盤績效做比較,則採用Jensen指標。在實證主題一的驗證中,利用模擬(simulation)的方法來研究第一階段三個經風險調整的重要模型Sharpe指標、Treynor指標、Jensen指標與基金累積報酬率(未經風險調整)在大多頭、大空頭市場下對基金績效的正確區別能力,發現四者對於異常績效的區別能力上其實非常類似,且整體而言區別能力都隨著異常報酬率預設值提高而上升。另外改變隨機抽樣的方式而以市值比大小來作為抽樣基礎,只會使各項指標的正確區別能力降低,四者結果仍然很接近。(二)衡量基金擇時選股能力的各種方法﹕可觀察基金經理人的內涵,當市場走「個股行情」或是市場走勢明確時,投資於選股能力佳的基金會有較佳的獲利情形。相反地,當市場多空看法分歧,個股走勢已脫離基本面而為市場大勢所左右時,投資於擇時能力佳的基金會有較佳的獲利情形。在實證主題二的前半部,利用Henriksson & Merton(1981)的模型針對台灣資料作實證研究,發現台灣的基金部分有選股能力卻完全沒有擇時能力。接著檢定模型殘差項,發現「有效性(efficiency)和一致性(consistency)」並未達成。此外參考了Jagannathan & Korajczyk(1986)對HM的批評而加入了非線性因素於HM模型中,重新對基金作擇時能力估計。在實證主題二的後半部,考慮了「二次方項」的市場因素之後,在同樣的資料下,基金擇時能力提昇了不少,只是在殘差項檢定上仍然存在異質變異數的情形。(三)評估持股比率變動的各種方法﹕本階段評估方法的起始概念都在計算持股比率與個股報酬率之間的相關性來判斷基金績效。愈晚近的模型不斷地改善早期模型的偏誤,像是「向下偏誤」(downward bias)與「存活性偏誤」(survivorship bias)、甚至異常報酬率的發生因素。然而本文並未對「評估持股比率變動的各種方法」作實證主題研究,因為直接代入數據作複雜運算、而不去考慮基金操作上的種種交易成本,將有可能發生倒置的結果,尤其在這個投信高度競爭的時代,手續費、管理費用不斷地有變化,不去考慮這個因素會非常冒險。 章節目錄 第壹章 緒論……………………………………………………… 1 第一節 研究動機、研究目的………………………………. 1 第二節 研究範圍……………………………………………. 4 第三節 研究架構……………………………………………. 4 第貳章 國內共同基金市場分析………………………………… 6 第一節 國內證券投資信託事業(SITE)…………………….. 6 第二節 投信事業的產品---共同基金………………………. 9 第三節 基金市場現狀說明…………………………………. 14 第參章 評估整體績效的各種方法……………………………… 17 第一節 單因素評估法………………………………………. 17 第二節 兩因素評估法………………………………………. 17 第三節 對整體績效評估法的看法…………………………. 26 第肆章 評估基金擇時選股能力的各種方法…………………… 35 第一節 分析投資組合的績效來源…………………………. 36 第二節 UD(Up-Down)模式…………………………………. 43 第三節 隨機變數(stochastic variable)模式………………….52 第伍章 評估持股比率變動的各種方法………………………… 65 第一節 早期觀察持股明細的模型…………………………. 65 第二節 近期觀察持股比率變動的模型……………………. 71 第陸章 實證主題設計…………………………………………… 80 第一節 實證主題內容………………………………………. 81 第二節 資料蒐集、樣本與相關變數的定義………………. 82 第三節 實證主題一的驗證…………………………………. 86 第四節 實證主題二的探討…………………………………. 98 第柒章 結論與建議……………………………………………… 116 第一節 結論…………………………………………………. 116 第二節 建議…………………………………………………. 119 參考文獻………………………………………………………….. 122

悅讀是指讀者自己挑選有趣的書籍,自發性地廣泛閱讀。本研究是要探討悅讀對國中生的閱讀動機,閱讀能力,和寫作能力的影響。本實驗邀請台北市某所國中61位的八年級生參加,分為實驗組(悅讀組)和對照組(傳統閱讀組)。本實驗共為期23週,在學生的英文閱讀課進行,每週一次,每次45分鐘。實驗期間, 實驗組在上閱讀課時只專心於閱讀自己所選的圖畫故事書,而對照組則繼續原來由老師所主導的傳統閱讀課程。實驗進行前後二組學生都接受全民英檢的閱讀和寫作能力測驗及閱讀動機評量。這些測驗資料由電腦進行量化處理與分析,個別訪談結果則用來輔助說明結果與討論。 結果顯示,經過悅讀的實驗,學生的整體閱讀動機提升了。此外,多面向的動機顯示,參與者的閱讀自信和閱讀成就與目地深受悅讀課程所影響,尤其是參與者從悅讀中產生很強的愉悅感,也增強了自信心。此結果證明了悅讀的最大功能—增進愉悅感。但是此研究並未發現悅讀能有效地改進參與者的閱讀和寫作能力。 因為小樣本及有限的資料,本實驗結果只能提供建議性而非決地性的結果,不過本實驗還是能提供一些教育性的建議。如悅讀能納入學校課程當作正規英文課的輔助。學校每天的早自習是讓學生悅讀的最佳時間。另外,賦予不同程度的學生不同的閱讀目標與配合適當的閱讀活動能增進他們的英語能力。爲了更深刻了解悅讀對國中生的效益,最好從校內全體的七年級生開始進行為期三年的悅讀課程,最後以高中入學的基本學力測驗英文科成績來檢驗其成效。期待面對繁重課業壓力的國中生能透過悅讀快樂地並有效地學習英文。 / Pleasure reading refers to any reading in which self-motivated readers pick up books they are interested in and engage themselves in those books. Pleasure reading has long been recognized as a powerful tool for fostering reading interest and enhancing literacy development. This study aimed to investigate the impacts of pleasure reading on EFL junior high school students’ reading motivation, reading comprehension, and writing ability. Sixty-one eighth graders in a junior high school in Taipei were divided into the experimental group (pleasure reading group) and the control group (traditional reading group). This program was carried out during the English Reading class, once a week with 45 minutes for each period. During the 23-week reading program, the experimental group only focused on reading self-selected picture books without any instructions while the control group still received the skill-based reading approach. Before and after the program, their reading and writing ability were examined by the reading and writing tests of General English Proficiency Test (GEPT) and their reading motivation was measured by the Motivation for Reading Questionnaire (MRQ). The data collected were analyzed quantitatively and the interview data were utilized to interpret and support the findings. The results revealed that the experimental group participants’ overall reading motivation was enhanced significantly after the program. As for the multifaceted motivation, the results showed that the participants’ “reading self-efficacy” and “reading achievement values and goals” were influenced strongly by pleasure reading. Among the 12 reading dimensions, “enjoyment” was the most significant factor. All the findings confirmed the main value of pleasure reading-- reading for enjoyment, and such enjoyment promoted students’ reading motivation very positively. With respect to the participants’ reading and writing ability, the results did not show significant improvement. Pleasure reading did not influence the participants’ language proficiency positively. However, both groups made some progress in the posttest in the gain score. Therefore, pleasure reading appeared to be at least as effective as the traditional reading approach. Pleasure reading was more interesting and enjoyable for junior high students. Although the results may not be taken as conclusive because of limited data and small samples, this study still provides some pedagogical implications and suggestions. Pleasure reading can be implemented into school curriculum as a counterpart of regular English class, a kind of skill-based English class. The school’s morning session is a good time for students to read self-chosen materials. Moderate tasks should be set for students with different language levels to conquer. Appropriate reading activities can be integrated to help stimulate students’ reading. To get a clear picture of its effect on junior high level students, it is necessary to conduct the program for a longer duration and with larger samples. Therefore, it is suggested that further study can start with all the seventh graders in junior high schools and the study should last for three years. The entrance exam of senior high school, the Basic Competence Test can be adopted as the measurement of language proficiency. It is expected that junior high students under academic pressure can learn English happily and effectively.

中國對開發中國家之能源策略與外交:蘇丹與委內瑞拉案例比較 / China’s Energy Strategies and Diplomacy toward Developing Country-Cases Comparison between Sudan and Venezuela

易孔道, Yin, Kung Daw Unknown Date (has links)
能源是經濟和社會發展的重要基礎和戰略資源。近百年中,能源安全不斷的被各國列為首要問題。隨著中國改革開放,國家經濟不斷成長,成為世界經濟大國,其能源的需求量日趨增加,從自給自足到至今依賴進口,使中國將能源外交列為外交戰略的主要目標,藉由走出去得戰略,積極到海外尋找能源。在這種情況下,能源外交顯然將成為繼大國外交與周邊外交後,中國外交政策的第三個重要環節。 開發中國家具有豐富的能源,再加上中國以開發中國家自居,因此開發中國家在中國的外交政策上,佔有重要地位,且可配合中國國家經濟發展。中國藉由其與開發中國家建立並維持良好的外交關係,以為中國尋找迫切需要的能源。 中國積極透過多邊組織或是雙邊接觸,向非洲、拉丁美洲尋找油源。中國能源問題不僅關係著中國的經濟發展,在擴展能源佈局全球的同時,也引起國際的注意,意涵著這是國際能源戰略問題,更是國際外交爭議性議題。 中國為化解能源進口來源過於集中的風險,於是拉美及非洲成為中國石油進口的戰略來源地。中國將觸角伸向拉美及非洲地區,其中對委內瑞拉及蘇丹這兩個國家最為積極,近期拉美的左傾化浪潮,委內瑞拉查韋斯政權與美國對抗,以及蘇丹有關達富爾的人權問題,使得中國的能源外交被國際社會說成與美國分庭抗禮及罔顧人權,造成中國受國際社會的譴責。 本文研究發現,中國與開發中國家能源外交有助於提升中國國際影響力,「能源競爭」與「權力競爭」是中國對非洲及拉丁美洲的能源外交目的。中國的能源外交對各地區之目的有所不同,不一定都是以獲取能源為主要目的,有時權力競爭反而佔據相當的份量,即中國能源外交之目的有時為了能源競爭,此時著重於取得能源;但有時卻不是為了能源競爭,能源本身不是目的,而只是工具,其真正目的是權力競爭。 / Energy is an important strategic resource and the critical basis of economic and social development. During the last hundred years, energy security has been identified as primary problem. With its successful open-door reform, China became the world economic giant of the constantly growing up of the national economy. With the increasing needs of oil energy day by day, China was transferred from an oil self-sufficient country to an oil import one. Now, one goal of the diplomatic strategy is the energy diplomacy. With the strategy of “going out” looking for the energy abroad, China is searching for oil resource actively. In this situation, the diplomacy of energy will obviously become the third important aspect of the China’s foreign policy, in addition to major power diplomacy and diplomacy with neighboring countries. Developing countries with the abundant energy, plus China itself poses as a developing country, developing countries occupies an important position in Chinese foreign policy in general, China's national economic development in particular. For the purpose of acquisition of oil energy, China has to maintain actively good diplomatic relations for developing countries. So China looks for the oil source to Africa, Latin America through both multilateral organizations and bilateral relations. The question of the Chinese energy is not merely only concerning the economic development of China, but also its global strategy of energy acquisition. So that it has attracted international concerns and became a controversial issue of international diplomacy. China has made every effort to reduce the risk that the import of energy resources overly concentrates, and, consequently, Latin America and Africa become the strategic source of China's petroleum imports. China stretches the feeler to Latin America and Africa, among them the most positive to these are two countries, i.e., Venezuela and Sudan. The left-leaning political tide in Latin America recently, the regime of Chavez in Venezuela confronting with U.S.A., and the human rights issue of Sudan, China’s energy diplomacy is to be condemned by the international community, because of deliberately confrontation with the United States and ignorance of human rights. This study discovers that the energy diplomacy will be helpful for China’s influences in the international arena and its major purpose is for either energy or power in Africa and Latin America. The Chinese diplomacy of energy varies in terms of geographic factor. Sometimes, Chinese energy diplomacy is for energy acquisition so as to resolve its development needs, sometimes for power and energy is only an instrument.

從創新擴散模型分析台灣能源技術服務業(ESCO)的發展 / Using "Diffusion of Innovation" theory to analyze the development of ESCO business in Taiwan

林恭平, Lin, Kung Ping Unknown Date (has links)
在當前全球受到全球暖化所帶來許許多多氣候異常現象,造成人類生命財產安全的嚴重影響,世界各國莫不致力於節能減碳,開發再生能源來取代目前的石化燃料。 美國在1970年代能源危機期間所提出的ESCO(Energy Service Company) 的概念,如今又獲得各國的青睞。 台灣於引進此一新的概念也有十年之久,在業界也一直不斷有專家,技術人員不斷的投入努力,經濟部能源局近年來也不斷的倡導節能服務的好處,甚至還推動一些補貼措施。 本研究主要是以Everett M. Rogers的創新擴散模型為理論基礎,研究台灣ESCO產業為何無法如高科技消費性電子產品般很快速的擴散到社會每一個角落,有哪些因素阻礙了台灣ESCO產業的發展。 本研究主要得到的結論如下,阻礙台灣ESCO產業擴散的因素可從三個構面來分析,第一個構面為創新擴散構面,Rogers所提出的五種創新認知屬性對於台灣ESCO產業的擴散都有一定程度的影響。另外在溝通管道上所採用的B2B行銷方式對於客戶決策也會影響擴散的速度。至於時間因素,本研究認為五年是比較恰當的觀察台灣ESCO產業發展的觀察期間。第二個構面可以從台灣獨特的經濟特質來說明,台灣以中小企業為主的經濟環境無法如歐美般有Super-ESCO規模的公司,這也導致了客戶信賴度以及未能產生以服務為導向的ESCO能源服務,台灣若還是以設備買賣為主要ESCO產業的商業模式,是會阻礙此產業的發展。第三個構面為政府的角色,台灣政府在投入ESCO產業的資源及推動此產業發展的企圖心不若美國政府。 本研究經研究結論後,提出具體的建議: 一、 要加速此產業的創新擴散就必須加強 Rogers創新擴散模型中的可觀察性屬性。 二、 跨越產業鴻溝的重點在於讓早期採用者滿意ESCO的方案。運用保齡球道理論,讓早期採用者所形成的利基市場對於ESCO節能服務能夠滿意,產生具示範效果的成功案例,才能伺機擴張至其他的利基市場,最後形成龍捲風暴,順利跨越此產業的鴻溝。。 三、 本研究對於台灣ESCO產業的發展的看法是審慎保守的。台灣ESCO產業的發展絕不是短短幾年就可以看到成效,本研究建議以五年為一個觀察期。目前以中小企業為主的ESCO業者必須要儘快的建立自己的優勢,儘早建立口碑,未來才有機會生存。 / Global warming is the most seriously problem we are facing in 21th century. All the countries devoted to reduce the carbon emission in order to minimize the impact of climate change. The business model of ESCO (Energy Service Company), which has been created in US during 1970 energy crisis, now has been advocated worldwide. The ESCO business model has been introduced into Taiwan for more than 10 years. There are many talent people, specialist engaged in this business. Taiwan government has also promoted ESCO some subsidies. However, even the society put a lot of efforts to develop ESCO business, why this business cannot spread out as consumer electronics? This thesis adopts the theory of “Diffusion of innovation” from Everett M. Rogers, 1962. The main purpose of this study is to find out why ESCO service business model cannot diffuse like other high-tech products. Are there any obstacles slow down the development of this industry? This thesis comes to the conclusion of three faces, which can significantly influence the development of ESCO business in Taiwan. The first face based on the diffusion of innovation theory, the five attributes of innovation defined by Rogers will affect the development of ESCO industry in Taiwan. Of course, the B2B marketing approach will delay the propagation of the ESCO industry. Moreover, this study suggest that 5 years watching window should be appropriate to monitor the development of the ESCO industry in Taiwan. The second face is the Taiwan unique economics environment. The ESCO industry in Taiwan is formed mostly by Middle-small size enterprises. In comparison with US, there is no Super-ESCO company exists in Taiwan. This study found out the truth that the client is not confident on middle-small size company to provide ESCO service. The common business model of ESCO industry in Taiwan is still focusing on selling the energy efficient product instead of providing energy service to the client. The study believes that this kind of business model will severely impact the development of this industry. The third face of the conclusion is the government role in Taiwan. The study found out that Taiwan government didn’t allocate enough resources to assist developing ESCO business. This thesis not only indicated the obstacles to slow down the ESCO business in Taiwan but also provide some constructive initiatives. 1. We have to concentrate on the visible attributes in diffusion of innovation theory for ESCO industry. 2. In order to cross the chasm, ESCO has to satisfy the early adapters in the beginning. They can also build up the bowling pin model to keep the existing niche market and explore the adjacent niche market when the opportunity comes. Thus, ESCO can create tornado period and cross the chasm in the industry. 3. The study is conservative about the development of Taiwan ESCO industry. We suggest that 5 years watching window should be proper to monitor the development of Taiwan ESCO industry. The ESCO companies in Taiwan should establish their strengths the sooner the better in order to survive for the future severe market competition.
