What are the similarities and differences between government corporations and private corporations?

Government corporations and private corporations both operate in a business-like manner, aiming to provide services and generate revenue. However, government corporations are established by the government to serve public interests, often providing services that may not be profitable for private entities, while private corporations are driven primarily by profit motives and shareholder interests. Additionally, government corporations may receive funding and support from the government, whereas private corporations rely on private investment and market performance.
