The government plays four key roles in the business environment: regulatory, promotional, entrepreneurial, and planning. For the regulatory role, the government regulates business entry, operations, and results through policies like licensing and profit/dividend ceilings. Promotionally, the government establishes infrastructure and training institutions to encourage entrepreneurship. As an entrepreneur, the government operates businesses in sectors like steel and petroleum. Finally, in its planning role, the government aims to optimally allocate resources through plans guiding industry growth and prioritizing sectors.
