碩士 === 國立成功大學 === 資源工程學系 === 102 === The phenomenon of rebound effect has sparkd considerable academic debate in recent years over the effectiveness of energy conversation policy. With advances in technology, energy-saving equipment could enhance the efficiency of energy use and reduce the energy consumption. However, the expectation, in general, for efficiency improvement involves the energy saving comes from technology, ignoring the change in energy efficiency may change the processes in production or consumer behaviors. The potential energy saving may be overestimated if the rebound effect is neglected, then cause the energy policies fail to achieve the target. Most of the academic literatures on rebound effect focus on the assement of a single industry or the economy system as a whole. Since the industries in economy are interdependent and have their own characterstics. A single industry to improve efficiency not only changes its use of energy, also spills over to other industries. This study applies the Input-Output (I-O) analysis to identify the characteristics and use of energy consumptions in different industries, and to analyze the rebound by supply-driven I-O model. Actual energy saving were scrutinized by incorporating rebound effect. According to the results of this study, the rebound effects are less than 10% in most industries in 2006, and the average is about 3.75%. The industry with higher forward linkage generally has a higher rebound effect. The industries with higher rebound effect include Basic Chemical Industry, Other Metals, Mining, Railways and Highways, and Chemicals. The industries with lower rebound effects are Fishery, Food Processing, Alcohol and Tabacco, Rayon Manufacturing, Textile and Leather, and Means of Transport. Considering the rebound effect, the energy intensity and rebound effect will affect the energy saving. Basically, the higher energy-intensity industry still has a higher potential for energy saving. Although the potential energy savings were offset partially by rebound effects, Transportation and Manufacturing of Intermediate Product still have higher potential energy savings. Through the linkage of industries, improve energy efficiency in these industries can get better results.
