영문 초록

The total energy requirement, often called the energy intensity, is the measure of the direct and indirect energy, measured in physical units, required to produce a unit of each sector`s output. However, until now in computing the energy intensity of output, the Leontief inverse matrix of the traditional input-output model has been used. Each element of the Leontief inverse, c_(ij) represents the direct and indirect output requirements to support a unit of final demand. At this point, we can find a significant error in computing the energy intensity. The identical meaning cannot exist between the notion of direct and indirect input requirements to support a unit of final demand and that to produce a unit of gross output in the open input-output model. The study objectives of this paper are as follows. (1) We introduce "the general relation" verified by the authors, between two different notions of direct and indirect input requirements, or between two different total requirements matrices. (2) We recalculate each sector`s energy intensity for the Korean manufacturing industry for the years 1975 and 1990 by using "the general relation."
