This paper intends to show that the fiscal equalization effect of a local grant tax among prefectural governments became gradually small after the year in 1991, and change of operating way of a local grant tax system bring about such a change.
This paper, first, reviews a function of a local grant tax. Then, we confirmed about the importance of a fiscal equalization function.
Secondly, we examine regression analysis about the fiscal equalization effect of a local grant tax among prefectural governments by using 47 prefecture's data during 1976-93 years.
Finally, we summarize the arguments by examining its implication as follows: (i) Fiscal equalization effect of a local grant tax among prefectural governments enlarged year after year during 1976-90 years, while that effect is gradually small after the year in 1991. (ii) Change of operating way of a local grant tax system promoting local independent public works, brings about such a change.
