"The general relation" between the two different notions of direct and indirect input requirements was proposed by Gim and Kim(1998). Moreover, the element of the Leontief inverse(or output requirement coefficients for final demand) C<SUB>ij</SUB> can be decomposed into four different parts as the final demand, the direct, the technical indirect, and the interrelated indirect effects(Gim, 2002; Gim and Kim, 2005). From the decomposition by factors in the Leontief inverse, we can get two different input requirement coefficients and two different output requirement coefficients.
The study objectives of this paper, based on the cumulative research outcomes mentioned above, can be summarized as follows. (1) We intend to introduce the characteristics and economic implications of the Leontief inverse expressed as the solution of the total output x, shown as Equation (5), in the interindustry equilibrium system. (2) We illustrate in detail the misunderstandings and confusion on the exact concept of the Leontief inverse from the various existing literature.
The major misunderstandings on the Leontief inverse can be classified into three categories: net multipliers, infinite sums, and power series. Oosterhaven and Stelder(2002) introduced the new concept of net multipliers. The problem with their
work is that they implicitly assumed that the Leontief inverse C<SUP>f</SUP> can be multiplied by the total output x. The multiplication of (I-A)?¹ by x does not make sense because there is no consecutive connections between elements in the Leontief inverse C<SUP>f</SUP> and the total output x. And also, we can only consider an infinite sum as shown in Equation (17). In this case, it is sure that (I-A)?¹ 1 is the Leontief inverse. In spite of that, it is a still misunderstanding assuming that the Leontief inverse (I-A)?¹ can be multiplied by the total output x. For power series, shown as Equation (12), the meaning of the technical coefficients matrix A, generally defined as the ratio of input to output, is changed from the concept for output, shown as Equation (18), to the concept for final demand.
