According to the theory of macroeconomics, the economy is divided into three main and large sectors:
The first sector focuses on gathering raw materials and includes companies involved in mining, timber, oil exploration, as well as agricultural industries and fishing.
The second sector is focused on goods and their sale, which includes manufacturing industries and industries that produce tangible products for sale.
Like this: (The automobile industry, furniture, clothing trade, etc.). The third sector, known as the “services” sector, is responsible for providing and producing services that are fundamentally intangible. This sector includes various industries such as transportation, healthcare, education, finance, tourism, hospitality, and more, focusing on delivering services rather than physical goods.
Like this: Entertainment, healthcare, transportation, hospitality, restaurants, and more are part of the services sector. This theory suggests that as countries advance, their economies are increasingly based on the third sector, in contrast to developing or less advanced countries that largely depend on the first sector (for example, in the United States, the services sector makes up 85% of the economy). The shift towards a service-based economy reflects the increasing demand for intangible services as societies modernize and diversify.
