The Impact Of Infrastructure Investment On Economic Growth: Case Of Cameroon

This study examines the impactof infrastructure capitalon economic growth in Cameroon. The study model is based on Solowaugmented growth theory where infrastructure capital is the sole determinant of economic growth. All regressions were run onEviews employing a simple time series econometric model. Our test for unit roots and cointegration show that there is a long-run equilibrium relationship at which the series become stationary.The study includes labour, human capital index, gross fixed capital formation, electricity generation, improved water source as percentage of total population with access and the ICTs(information and communication technologies)to be the regressors and real gross domestic product to be the regressand using a time series data from 1977 – 2011. The findings show thatgross capital formation, electricity generation and improved water source are significant and positively associated to economic growth in Cameroon in the long run. On the other hand, the ICTs were found to have a significant but negative impact on economic growth. Policies aimed at stimulating electricity supply should be implemented and we advised massive investment in transformers and electricity poles to avert the negative effect of electricity transmission and distribution losses. We also advocate for better water sources infrastructure especially in rural areas. We encourage investment towards ICTs management and expertise trainings to reap the full benefits of such products and services on Cameroon?s economic growth.
