This paper analyses the characteristics of interregional competition and complementarity in Colombia during the period 1960-2000. The analysis is based on an application of the Dendrinos-Sonis model which is calculated using the SUR estimator. The evidence shows a country with a low level of integration among the different regions and a high level of competition. These findings are consistent with the observed income polarization process. Policymakers must take into account the competitive regional relationships to propose adequate policies such as the adoption of regional redistribution strategies, or other interventions that might enhance regional interaction and integration.
