More specifically, this study uses the parts of IO analysis, namely simple output multiplier, simple household income multiplier, index of the power of dispersion, and index of the sensitivity of dispersion as analysis devices. The analysis period of this study is 2011-2015. The results show that the consistency of several industries in influencing the Japanese national economy on the analysis period could be seen from both multipliers. Besides, the characteristics of almost all Japanese industrial sectors on the period of analysis did not change.
