The study examines the impact of official development assistance (ODA) in constructing road transport infrastructure on Vietnam’s economic growth. The authors select gross domestic product (GDP) to represent economic growth and test the influence of ODA in constructing road traffic infrastructure on Vietnam's GDP. Based on the references and analysis of previous studies, the authors propose an impact assessment model of ODA in constructing road transport infrastructure, Foreign direct investment (FDI), Domestic Investment (VDT) and Labor Force (Labor) to economic growth through GDP as a dependent variable. The regression results show that the ODA had a positive impact on GDP. Moreover, ODA plays an important role in constructing road transport infrastructure on Vietnam’s economic growth.
