The purpose of this study is to examine how the decreased taxation effect and the increased taxation effect have influenced the investment by changing the corporation Tax rate. The analysis based upon the investment theory model is made by the expense control of Abel, Lucus, Gould, Tread, Way. It was to survey how the required and temporary change have influenced to the investment followed by the funds raising ways. As a result of bilateral analysis for the effects of the required rate change and the temporary rate change, it is found that the both part`s difference is that the equity capital has influenced a lot to the cost of depreciation. Also, in some extreme case, the investment effect by the rate change turned out differently when the full amount of investmeat capital was raised by the equity Capital and the deficit. In the end, our problem on tax law is that the dividend on the capital is not regarded as a expense, therefore, the deficit raise which can be allowed with the expense as the debt interest will be surely beneficial this is the systemic problem.
