Effects of Public Investments on Gross Domestic Product: Case of Artvin Province

Öz

This paper investigates that the effects of total real public investments made to Artvin upon the real per capita income in Artvin. The relationship between public investments and income is analyzed using Granger causality and cointegration tests. Also, the analysis has covered the period of 1988-2017, based on annual observations. According to the results of Granger test, there is a causality relationship at 5% level of statistically significance from public investments to the income of Artvin citizens, whereas there isn't any significant causal relationship from income to public investments. A long-term relationship hasn’t been determined between public investments and per capita income in Artvin in Johansen cointegration test.

Öz

Çalışmada kamu yatırımları ile kişi başına düşen gelir arasındaki ilişki Granger nedensellik ve eş-bütünleşme testleri kullanılarak analiz edilmektedir. Ayrıca, analiz 1988 – 2017 dönemini kapsamakta ve yıllık gözlemlere dayanmaktadır. Granger nedensellik testinden elde edilen sonuçlara göre, Artvin’e yapılan kamu yatırımlarından Artvin halkının kişi başına düşen gelirine doğru % 5 önem seviyesinde istatistiki olarak anlamlı bir nedensellik varken, Artvin’de kişi başına düşen gelirden kamu yatırımlarına doğru anlamlı bir nedensellik bulunmamaktadır. Yapılan Johansen eş-bütünleşme testinde Artvin’de kamu yatırımlarıyla kişi başına düşen gelir arasında anlamlı düzeyde uzun dönemli bir ilişkinin olmadığı tespit edilmiştir.
