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.

台灣為海島型國家，因自有能源貧乏，99%以上的能源仰賴國外進口。為確保能源供給之穩定與安全，除發展再生能源之外，提高能源終端使用效率為重要之解決手段。熱泵系統因其獨特之節能減碳效果，在歐美先進國家備受重視，極力推廣。基此，考量台灣氣候類型及居住型態，評估熱泵熱水系統的適用性及成本效益分析，爰為本研究之動機與目的。 為了彰顯應用熱泵系統在不同地區氣候條件與能源價格之差異，本研究將台灣劃分為12個地區，並且以電能、LPG桶裝瓦斯、NG管線瓦斯三種現有之住宅用熱水系統作為可供替代之選項，利用迴避成本(Avoided Cost)推估台灣各地區住宅部門改採熱泵熱水系統之成本效益。此外，參考歐美先進國家熱泵系統補助政策，以及台灣現有「太陽能熱水系統推廣獎勵措施」之政府政策補助方案，設定各相關參數，俾模擬政府補貼方案情境下之成本效益分析。 分析結果以淨現值(Net Present Value)、益本比(Benefit-Cost Ratio)及折現回收期(Discounted Payback Period )呈現，結論可從兩個觀點之檢定加以評估。其一、以「參與者檢定」評估是否有足夠的經濟誘因，促使住宅用戶裝設熱泵熱水系統。其二、以「總資源成本檢定」，評估推廣熱泵系統對於整體社會是否具有淨效益。 本研究中全台12個地區，若以熱泵系統取代電能熱水系統、LPG瓦斯熱水系統、NG瓦斯熱水系統三種既有設備，交叉比對之33個替代方案，由「參與者檢定」之結果顯示，所有替代方案之益本比均大於1.1；折現回收期最長達11.3年，最短僅3.2年。若模擬政府補助18,000名用戶採用熱泵系統，則「總資源成本檢定」之結果中，所有替代方案之益本比介乎1至1.73之間；折現回收期最長達14.9年，最短僅5.4年；住宅部門以熱泵替代現有電能、LPG瓦斯、NG瓦斯熱水系統至少可降低碳排放量每年2,707公噸。三種替代類別中以電能熱水系統替代方案益本比最高(介乎1.55至1.73)；LPG瓦斯替代方案之益本比居次(介乎1.19至1.28)；NG瓦斯替代方案益本比最低(介乎1.0至1.06)。全台12個地區考量環境溫度差異之影響以南投分區改採熱泵系統的益本比最高(電能替代1.73、LPG瓦斯替代1.28、NG瓦斯替代1.06)，屏東分區的益本比為最低(電能替代1.55、LPG瓦斯替代1.19、NG瓦斯替代1.0)。 若考量熱泵系統市場滲透率，以熱泵取代NG瓦斯熱水系統之市佔率達5%、20%、50%時，台灣整體社會的淨現值分別為251百萬元、1,006百萬元與2,514百萬元，且每年可減少碳排放量27,169公噸、108,675公噸以及271,687公噸。 / As an island country, 99% energy supply in Taiwan depends on importation due to the very limited endogenous energy. In order to maintain both energy security and stability, improving energy efficiency of consumer end-use is an important government policy. Heat pump systems have been widely applied and strongly promoted in Europe and United State for its uniquely energy saving and CO2 reducing capability. Therefore, the motivation of this study is to access the regional applicability of heat pump water heating system for Taiwan’s climate and residential building types by cost-benefit analysis method. To demonstrate the regional difference of climatic conditions and energy prices heat pump application, Taiwan is divided in twelve regions with three kinds of alternative residential water heating systems (i.e. electric heating, LPG tank heating, and NG pipe heating). Under these conditions, we utilize the avoided cost method to access itemized costs and benefits of heat pump water heating systems in various regional families in Taiwan. In addition, referring to heat pump incentive scheme in advanced European countries and North America while considering solar water heating systems incentive policy in Taiwan, we also simulate variation of parameters (such as cash rebate subside, total residential heat pump user numbers )of heat pump system subsidy program. The outcome of cost-benefit analysis is presented in a form as net present value (NPV), benefit-cost ratio (BCR), and discounted payback period (DP). The results could be analyzed by test from two different perspectives including Participant Test (PCT) from participant perspective and Total Resource Cost Test (TRC) from overall sociality perspective. All of the 33 alternative programs constituted by 12 regions with electric , LPG and NG systems, for PCT, BCR, all 33 alternative programs are greater than 1.1; DP are between 3.2 to 11.3 years. For TRC, BCR, all 33 alternative programs are greater than 1 but less than 1.73; DP are between 5.4 to 14.9 years. Residential building adopting heat pump could reduce 2,707 tons carbon emissions annually. For the three types of alternative system, BCR of electric heating alternative program is the largest and NG alternative program being the least. For all of the 12 regions, BCR of Nantou region is the largest for adopting heat pump while BCR of Pingtung region is the smallest. NPV of overall Taiwan with market penetration reaching 5%, 20% and 50% substitution rate from heat pump system to NG water heating system are 251 million NT$, 1,006 million NT$, and 2,514 million NT$ respectively. Carbon emissions reduce 27,169 tons, 108,675 tons and 271,687 tons annually.

台灣工業區因應工業發展之需要已經歷經近三十年之發展，隨著大環境及產業結構的改變，加上工業區因為年代久遠，區內設備老舊失修且區內管理服務中心無法滿足廠商需求，使區內廠商外移嚴重，產生工業區土地閒置問題，於是工業區再造議題應聲而起。觀察台灣島內對於工業區再造之措施，都僅於區內環境及設備之改善，土地閒置問題仍然嚴重。 另一方面，因為地球氣候暖化問題嚴重，國際間對於二氧化碳排放量的管制隨著京都議定書的訂定產生標準及制裁行動；而油價持續上漲，如何節省能源也成為各國熱烈討論的 話題。台灣本島人口僅占全球0.4%，但二氧化碳排放量比例確高達0.96%；能源資源有限，然台灣能源皆需仰賴進口，身為地球之一份子，如何節能減碳亦成為台灣責無旁貸的目標。 在討論二氧化碳減量的方式中，增加植樹造林面積是被認為成本最低且對國家整體經濟之衝擊面影響最小，同時京都議定書對於造林減碳的方式亦予以肯定。 是否可以全面植樹來再造工業區成為本文之重點，藉由工業區以全面植樹再造之利弊分析來提供另一思維，既可解決工業區再造問題又能達到節能減碳的目標。 本文選定林口工二工業區作為個案，以其全面植樹之淨現值等資本預算方析及SWOT分析來說明其可行性，希望作為台灣工業區再造之參考。 / The industrial districts in Taiwan are facing the problem of land unused due to the movement of factories inside the district and the reason is that the old environmental facilities and the service of district center being unable to meet the request of factories with the change of external environment and industrial structure. How to regenerate these industrial districts becomes a critical issue. Using the measures which only focus on the improvement of environment and facilities can not solve the problem. On the other hand, to control and punish the heavy CO2 emission has been taken globally with the implement of Kyoto Protocol in order to ease the problem of climate warming on the earth. With the rapid rise of oil price, how to save the energy also becomes the hot issue. Taiwan island is with 0.4% of global population, compared with the high percent of 0.96% on the CO2 emission and the energy is imported mostly, as the member of the earth village, to save the energy and decrease the CO2 emission becomes the inevitable responsibility and important objective. Analyzing the possibility to plant the tree comprehensively to regenerate the old industrial district is the key point of this study, hoping to provide another kind of thinking on this issue, Moreover, to meet the goal of saving energy and decreasing CO2 emission. Based on the case study of Linko industrial district，the measure of NPV the kind of capital budget analysis and SWOT analysis are used as the reference to regenerate the old industrial district in Taiwan.
