- 摘要
- 國際研究中不乏探討產能利用率與能源消費、能源效率間的關係，但過往國內文獻以因素分 解法研析國家或工業部門能源消費量與密集度時，並未考慮產能利用率帶來的影響。本文應用對數 平均數迪式指數分解法，將2014-2019年我國工業部門能源消費量的變動，除拆解成能源密集度、 產業結構與經濟活動效果外，進一步增列產能利用率變動效果，探究我國工業部門近年能源消費成 長因素。結果顯示，2014-2019年我國工業部門能源消費量減少498千公秉油當量。其中，能源密集 度與經濟活動效果對我國工業部門能源消費量的影響較大，2014-2019年間能源密集度變動累計降 低能源消費量6,469千公秉油當量，但經濟活動亦促使能源消費量增加6,881千公秉油當量。而2014- 2019年我國工業部門產業結構變動則降低能源消費量700千公秉油當量。此外，本研究以兩種產能 利用率數值評估對能源消費量的影響，結果均指出產能利用率造成的影響最小。鑑於經濟成長對工 業部門能源消費量的影響效果甚高，惟有透過持續提升能源效率，方能減緩經濟發展伴隨的用能成 長。而現行節能或提升能源效率的政策，有助於減少工業部門能源消費量，因而除宜持續維持既有 措施外，尚須減少化石燃料補貼、促使能源價格合理化以反映成本、考慮課徵碳稅、能源稅或碳 費、採行節能證書交易機制等，以多元工具促進工業部門能源效率，進而降低耗能量。

- There are many international studies to discuss the relationship among capacity utilization, energy consumption, and energy efficiency. However, when analyzing the energy consumption and intensity of the country or industrial sector by factor decomposition in the past domestic literature, few studies consider the possible impact of capacity utilization. This paper applies the logarithmic mean divisia index to disassemble the changes in energy consumption in Taiwan's industrial sector from 2014 to 2019. Apart from the effects of energy intensity, industrial structure and economic activities, we further add the effects of capacity utilization for exploring the impact factors of energy consumption in Taiwan's industrial sector during recent years. The research results show that the energy consumption of Taiwan's industrial sector decreased by 498 thousand KLOE from 2014 to 2019. Among them, energy intensity and economic activities have a lion share on the energy consumption of Taiwan's industrial sector. The improvement of energy intensity from 2014 and 2019 has reduced energy consumption by 6,469 thousand KLOE, but economic activities have increased by 6,881 KLOE as well. Then, the changes in the industrial structure have reduced energy consumption by 700 thousand KLOE in Taiwan's industrial sector during the same period. In additional, we uses two methods to calculate capacity utilization and their impacts on energy consumption. It Indicates that the capacity utilization of Taiwan's industrial sector has the smallest impact on energy consumption. Because the energy consumption of Taiwan's industrial sector will increase with economic growth, it is important to offset the effect through improving energy efficiency. The result has showed that current energy-saving policies were helpful to achieve energy conservation in the industrial sector. However, in addition to keep exercising existing measures, it is also necessary to reduce fossil fuel subsidies, rationalize energy prices to reflect costs, consider carbon tax, energy tax or carbon levy, introduce tradable white certificates, and so on in order to promote energy efficiency and reduce energy consumption in the industrial sector.
