Abstract: Public infrastructure investment is a crucial factor in the economic growth of regions and an essential process of local growth in the economically disadvantaged regions of the United States. This paper provides a thorough analysis of both theories and empirical research on the short and long-term effects of infrastructure, specifically, transportation, broadband, energy, and investment in public facilities, and analyzes their productivity, employment, and equity consequences in the region. Empirical studies reveal that infrastructure projects have significant short-run multipliers because they stimulate demand and create jobs, and at the same time, provide long-run benefits by increasing efficiency, increasing trade opportunities, and improving the quality of life. The review recognizes that the results vary across regions, which is highly influenced by the local socio-economic factors, such as the urban density, underused assets, and institutional capacity. The place-based policy frameworks, including the Promise Zones and the Infrastructure Investment and Jobs Act (IIJA, 2021), highlight the need to tailor investments to the needs of the communities. However, ongoing challenges stem from structural disadvantages and politicized fund distribution. The analysis underscores the importance of complementary measures, such as risk management, regulatory compliance, and transparency, to ensure investments are sustainable and equitable. Finally, infrastructure investment may be a decisive factor in making the economy more resilient. However, its ability to reduce spatial inequality hinges on careful planning and context-sensitive design.
