Public enterprises are businesses owned and operated by the government. They aim to provide essential services and goods to the public, often in sectors like transportation, energy, and healthcare. These enterprises are funded by taxpayer money and are expected to operate in the public interest rather than for profit. Examples of public enterprises include public transportation systems, state-owned oil companies, and public hospitals. They play a crucial role in ensuring access to basic services, especially in areas where private companies may not invest due to lower profitability.
