ENThe article provides a theoretical and empirical analysis of the impact of competition policy on the national economy of a country with a developing culture of competition, through the effects of competition policy and the impact of deterrence of sanctions for breaches of competition. The theoretical analysis has revealed a positive relationship between a successful implementation of competition policy and the country's economic development. The article reviews the situation related to the implementation of competition policy in countries with developing/emerging culture of competition - Lithuania and Latvia. Quantitative research has shown that competition policy in countries with a developing/emerging culture of competition is mostly manifested through the same areas as in countries with a developed competition culture: the areas of innovation, investment, international trade and human resources. Qualitative research has shown that there is a positive tendency within countries with a developing/emerging culture of competition that more and more economic entities are ready to compete fairly, and the competition itself is considered as a value. In addition, while the deterrence from violations of competition law in countries with a developing/emerging competition culture is lower than in countries with a developed competition culture, the impact of an effective competition policy on the reduction of and deterrence from the intentions to violate competition is apparent.
