The relationship between private- public partnership investment strategies and infrastructure financing in Nigeria has been a topic of significant interest in recent years. Existing research suggests that Nigeria's rapidly growing private- public partnership can provide an important source of investment capital for infrastructure development. The main objective of this study is to examine how private-public partnerships influence infrastructure financing in Nigeria. The study covers a twenty-year period from 2004 to 2023. The study employed an ex-post research design, secondary data were employed in view of the fact that the information needed is historical in nature and available, this study employed Ordinary Least Square Regression Analysis with the aid of STATA software version 16.0. This technique is employed because of its detailed description of the relationship between one or more independent variables and a dependent variable. This study relied on the Modern Portfolio Theory and reveal that PPP investment strategy has a positive and significant relationship with infrastructure financing in Nigeria. In agreement with the research prediction, the result shown in Table 2 revealed that infrastructural funds have a positive significant relationship with infrastructural financing (β= .171; t= 9.60; p=0.000). Hence, Hypotheses H1 was supported. The hypothesis results are in line with the results of the previous studies (Eke et al., 2018; Vanguard, 2018; Okechukwu et al., 2016; Fapohunda, 2013), as well as the Nigerian regulations on PPP investment strategy. We therefore, recommend That PPP funds should be allocated on assets towards infrastructure investment, either through direct investment in infrastructure projects or through specialized investment vehicles.
