Additionally, competition helps prevent the concentration of economic power in the hands of a few dominant firms, which can lead to market distortions and reduced consumer welfare. Therefore, the state plays a crucial role in enforcing antitrust laws and regulations to ensure fair competition and prevent the abuse of market power. **
