The public sector of an economy includes

The public sector of an economy includes nationalized industries. These are businesses or organizations that are owned and operated by the government or state, and are responsible for providing essential goods and services to the public, such as healthcare, education, transportation, and utilities. Nationalized industries are different from joint stock companies, which are owned by private individuals or organizations, and cooperative societies, which are owned and operated by their members. Pressure groups, on the other hand, are organizations that seek to influence government policy or public opinion on a particular issue, but are not part of the public sector of the economy.
