Abstract
Pieces of evidence were shown to supports that most of Japanese manufacturing corporation almost satisfy the condition where the profit before tax reaches its maximum, though the change in market size was found to shift the condition. The optimized state of management was defined as a final stationary state for both inside and outside of manufacturing corporations operating successfully in a free market. Some of the managerial indices and their ratios appeared to converge on respective final values or functions in the optimized state of management and those included the profit before tax, the ratio of R&D expenditure to marginal revenue, the amount of sales per capita, the ratio of R&D expenditure to the amount of sales, the ratio of marginal revenue to the amount of sales and others. Finally, it was concluded that JSR-RDM Model developed herein before constructed upon the basis that most of Japanese manufacturing corporations reach the optimized state of management.
