The concept of net multipliers, as introduced by Oosterhaven and Stelder(2002), accepts outputs as entries instead of final demand by multiplying ordinary multipliers by the final demand ratio over the sector's output in order to avoid overestimation and double-counting impacts. The idea of accepting outputs as entries is novel and remarkable but it appears that the concept of net multipliers had been developed based on the assumption that the Leontief inverse can be multiplied by the total output. In this note, we illustrate that the Leontief inverse may only be multiplied by the final demand and the multiplication of by does not make sense. It is because there is noconsecutive connectionsbetween and that the inverse may not be multiplied by. Gim and Kim(1998) proposed the general relation between the total direct and indirect input requirements matrix for a unit of final demand and the total direct and indirect input requirements matrix for a unit of gross output. And then we alternatively derived new multipliers based on the matrix that can solve consecutive connections problem in interindustry interdependence very naturally.
