Abstract
Efficient transport maintenance depots are crucial for reducing logistics costs in Nigeria's post-harvest sector. Panel data from 10 major transport maintenance depots over five years were analysed using a stochastic frontier model to estimate technical efficiency. The estimated average efficiency gain across all depots was 25%, with significant variability between depots. This study provides empirical evidence on the performance of Nigerian transport maintenance depots, contributing to their optimization and cost reduction. Implementing targeted interventions based on identified inefficiencies could further enhance depot operations and logistics performance. transport maintenance depots, efficiency gains, panel data analysis, Nigeria, stochastic frontier model The maintenance outcome was modelled as $Y<em>{it}=\beta</em>0+\beta<em>1X</em>{it}+u<em>i+\varepsilon</em>{it}$, with robustness checked using heteroskedasticity-consistent errors.
