Road Infrastructure Investment and Socio-Economic Growth in North-West Nigeria: A Panel Data Analysis

Abstract

This paper examines the relationship between road infrastructure investment and socio-economic growth in North-West Nigeria. Using panel data from six states over a ten-year period (2012–2022), the study employs econometric analysis to assess the effects of federal road investments on agricultural productivity, market access, and income levels in rural communities. Results demonstrate a statistically significant positive correlation between road quality improvements and per capita income growth (r=0.73, p<0.01). Regions with rehabilitated federal highways recorded a 22% increase in agricultural trade volumes over the study period. The findings highlight the critical role of road infrastructure as a catalyst for economic development and support sustained federal investment in road maintenance and expansion.
