Abstract:
This research investigated the role of Public-Private Partnerships (PPPs) in enhancing transport
infrastructure, focusing on the Nile River Port Project in South Sudan. The study sought to assess
how logistical constraints, funding mechanisms, and political instability impact the development
of transport infrastructure through PPP initiatives. Theoretical guidance was drawn from
Transaction Cost Economics (TCE), which emphasizes the importance of managing risks and
transactional costs in collaborative ventures like PPPs.
A case study design was adopted, incorporating both quantitative and qualitative data. The study
population included 100 participants, of which a sample of 80 was selected using purposive and
simple random sampling techniques. Data was collected through self-administered questionnaires
and interviews, targeting key stakeholders such as employees working on the Nile River Port
Project, local community members, PPP experts, and government officials. Data analysis was
conducted using the Statistical Package for Social Sciences (SPSS), where both descriptive and
inferential statistics were employed. Pearson’s correlation and regression analyses were performed
to assess relationships between variables.
The study found a strong positive correlation between logistical constraints and transport
infrastructure development (r = 0.662, p < 0.05). This indicated that logistical challenges, such as
delays in the delivery of materials and coordination inefficiencies, significantly hindered the
project’s progress. Funding mechanisms, however, showed a weak correlation with project success
(r = 0.198, p > 0.05), indicating that while funding is important, other factors such as logistical
management and political stability played a more significant role in determining project outcomes.
Political instability had a strong negative impact on the project, with a Pearson correlation of 0.702
(p < 0.05), confirming that instability disrupts timelines, investor confidence, and regulatory
environments.
In conclusion, logistical constraints and political instability were identified as major impediments
to the success of the Nile River Port Project, while funding mechanisms, though important, did not
emerge as a critical determinant of success. The study recommended enhancing logistical
coordination and stability in governance to improve the efficacy of PPP initiatives in South Sudan.
