The infrastructure investment could strongly influence the economic growth in the Western Balkans countries and contribute to improved regional cooperation and reconciliation and to faster integration into the EU. However, it is essential that public investments in infrastructure are properly financed and managed. To measure the impact of infrastructure indicators on economic growth, panel regression analysis was used for the period 2000-2021, in six Western Balkan countries. The paper addresses the important question of how to intensify investments in infrastructure to achieve sustainable growth in the Western Balkans. The obtained results confirm the earlier findings about the significant impact of energy, ITC, and road infrastructure on economic growth in the Western Balkans.
