MULTILEVEL DECOMPOSITION OF INDUSTRIAL ENERGY-CONSUMPTION

This study deals with the decomposition of industrial energy consumpti on at two levels of sector disaggregation or more. Past studies are re viewed and the need for multilevel decomposition is examined. Simple p rocedures for multilevel decomposition are presented. The proposed pro cedures, which are extensions of often used single-level decomposition procedures, allow estimates of various effects at different disaggreg ation levels to be made and interpreted in a consistent manner. Applic ation studies using the data of Singapore industry are presented. Seve ral application issues pertinent to multilevel decomposition are also discussed.
