Decomposition Analysis of Changes in Energy Intensity of the Thai Manufacturing Sector during 1991-2013

P. Boonkham and N. Leeprechanon
Abstract—This paper analyzes changes in energy intensity in the manufacturing sector in Thailand during 1991-2013, using the logarithmic mean Divisia index in multiplicative form. Results show that energy intensity in the manufacturing sector improved during this 22-year period, especially in the food & beverage, chemical, and unclassified sub-sectors; sub-sectors that did not show improvements were the fabricated metal, wood & furniture, textile, paper, non-metallic metal, and basic metal sub-sectors. Computational results show that energy consumption in the manufacturing sector increased significantly during 1991-2013 mainly on account of production effects, but that structural effects and intensity effects contributed only marginally to changes in energy consumption. The findings imply the need to balance restructuring policies within the manufacturing sector with efforts to reduce energy intensity, so as to attain sustainable economic development and improvements in energy efficiency, in accordance with Thailand’s long-term energy efficiency goals.

Index Terms—Energy intensity, decomposition analysis, logarithmic mean Divisia index.
