Özet:

Although there are many variables of national income, one of the critical variables is fixed capital investments. This study aims to examine the relationship between fixed capital investment and national revenue for the 1963-2018 period by categorizing the investments into two groups: public capital investments and private capital investments. In this study, Johansen cointegration and Granger Causality Test was applied to 56 years of the data set made of 3 variables by using the time series analysis technique. The results of the analysis show that there was no long-term cointegrated relationship between the variables. Moreover, there was a one-way causality relationship between national revenue and the private sector, as well as the private and public sector. Many policies have been implemented to increase national income, relieve the burden on the public, and encourage private sector fixed capital investments in the Turkey.This study recommends that the public should be more active in the economy through social politics, and private sector fixed capital investments should be used more effectively.
