Road Infrastructure, Mining Production, and Economic Growth in Muara Enim Regency: Evidence from 2010–2025

Abstract

The research focuses on examining the associations of road infrastructure, population growth, mining production, and economic growth in Muara Enim Regency, Indonesia from 2010 to 2025. With the use of secondary data in years, OLS regression analysis was used with 15 observations in total after considering the one-year lag of road length. The dependent variable includes road length lagged, population growth rate, mining production, and a dummy variable for the year 2020. Mining production was found to be positively and significantly associated with economic growth. The road length lagged has a negative relationship that is significant at 10% but not at 5%. No significant associations were found in population growth with economic growth. The dummy variable in 2020 had a negative and significant effect on economic growth. Approximately 80.70% of the variation in economic growth can be explained by the model. This finding emphasizes the strong link between mining output and economic performance in the region; however, the link between road networks and economic growth is statistically inconclusive. The study offers regionally relevant evidence to inform development strategies in the mining-dependent region. It must be noted that due to the limited sample size, the results can only be seen as statistical associations.
