Post-Investment Cost in Roads and Economic Development in a Peruvian Region

The objective of this research was to determine the relationship between the cost of post-investment in roads and economic development in the La Libertad region from 2015 to 2022. It was basic research with a quantitative approach, non-experimental design, and correlational scope. A documentary analysis was carried out by applying a record card, whose information collected was analyzed with descriptive, multiple correspondence and correlational techniques, finding that from 2015 to 2022, the post-investment costs reach PEN 85,562,363.47, resulting in the benefit of 1310.10 km. Likewise, it was found that economic development, through the indicator of monetary poverty, ranged between 20.83% and 31.90%, and that household access to the four basic services reached 77.9% in 2021 and 78.7% in 2022. It is concluded that in the La Libertad region, the costs of post-investment in roads are significantly related to economic development through the monetary poverty dimension in its two indicators: total and extreme poverty (r: −0.788, p-value: 0.02; r: −0.729, p-value: 0.04, respectively). The other dimensions did not show a relationship; however, these findings do not contradict the theoretical contributions and studies that do determine this.
