我國能源生產力分析

Analysis of Taiwan’s Energy Productivity

近年來我國的能源生產力呈現下降趨勢，本文就此一現象加以探討。結果發現，產業附加價值結構的變化並未反應在能源消費量的比例上，尤其是一些高耗能製造業的附加價值比重逐漸降低，但其能源消費比重卻未明顯下降。然而，此一結果僅可找出能源生產力下降的產業，卻不足以作為經濟政策的唯一依據，因為某些高耗能產業具有很高的產業關聯效果。國內能源部門加速自由化，並進一步放寬價格管制，使國內能源價格適度反映國際價格變化，將可使能源作更有經濟效率之配置。

This article examines the downward trend of Taiwan’s energy productivity in recent years. It finds that the change in the value-added share of GDP has not been proportionally reflected in the share of energy consumption, especially in some high energy-consuming industries. Although their share of GDP has dropped significantly, their share of energy consumption has remained almost the same during the past twelve years. The findings can not be considered as the only criteria in economic policy making, for some high energy-consuming industries do have relatively high backward and forward industrial linkage effects. To make our energy use more economically efficient, we should accelerate domestic energy market liberalization and further relax domestic energy price controls.
