Abstract
The dependences of principal managerial indices on the unit price of selling products proposed previously in this series are modified to fit in with all industrial corporations operating within the manufacturing industry. The general tendency known in manufacturing industry that a corporation operating at the upstream side carries a variety of products buy does not adopt the independent profit system is proved to be economically reasonable. A set of three major managerial indices is recommended for each side of output and input of an industrial corporation. Each of the three major indices for the output is then shown to be directly proportional to the respective one of three major indices for the input with a proportionality constant of a universal value as given by Eqs. (30)〜(32)) in the text, and the last one is reexamined with the data obtained in 1994.
