This study investigated the effect of investment via public private partnership on economic growth and development in Nigeria using data set spanning 1971 – 2020. Using the Ordinary Least Squares (OLS) method, the analysis was carried out on a set of data gotten from the World Bank’s Private Participation in Infrastructure (PPI) database and World Bank’s WDI. The study analysed the effects of total PPP investment on economic growth. The findings of the study surprisingly suggest that PPP investment negatively contributes to economic growth in Nigeria given the data set and period under study. This result is unexpected and could be attributed to limitations of data as well as poor reporting. This finding points to the importance of data that is adequate and consistently available over a long period. PPPs are becoming a necessary solution for strengthening infrastructure and generating economic growth in developing countries. Thus, understanding the empirical links, through research that exists between infrastructure investment using PPPs and economic growth is essential.
