Abstract
This paper proposes an analytical tool, based on a hybrid rectangular input-output framework expressed in both monetary terms and physical terms, to estimate the energy requirements contributed by energy-supply industries. The hybrid framework is introduced to relax the effects of different prices among industrial sectors on the input structure in physical terms. By applying hierarchy system to the hybrid model, we conducted a method to estimate the total energy requirements resulting from the production processes among non-energy sectors and analyzed in practical. The application of generalized inverse matrix theory to the extended input-output analysis also is discussed.
