State corporations are government-owned entities created to provide specific services or manage resources. They operate in various sectors, such as transportation, energy, and telecommunications, and aim to promote public welfare while generating revenue. These corporations are funded by taxpayer money and are accountable to the government. The primary goal of state corporations is to ensure that essential services are accessible to the public, often at lower costs than private companies. Examples include public transportation systems and state-owned energy companies. They play a crucial role in economic development and can help stabilize markets during times of crisis.
