An industry is the manufacturing of a good or service within a category. 1 Although industry is a broad term for any kind of economic production in economics and urban planning industry is a synonym for the secondary sector which is a type of economic activity involved in the manufacturing of raw materials into goods and products. 1
There are four key industrial economic sectors: the primary sector largely raw material extraction industries such as mining and farming; the secondary sector involving refining construction and manufacturing; the tertiary sector which deals with services and distribution of manufactured goods; and the quaternary sector a relatively new type of knowledge industry focusing on technological research design and development such as computer programming and biochemistry. A fifth quinary sector has been proposed encompassing nonprofit activities. The economy is also broadly separated into public sector and private sector with industry generally categorized as private.
Industry in the sense of manufacturing became a key sector of production in European and North American countries during the Industrial Revolution which upset previous mercantile and feudal economies through many successive rapid advances in technology such as the steel and coal production. It is aided by technological advances and has continued to develop into new types and sectors to this day. Industrial countries then assumed a capitalist economic policy. Railroads and steam-powered ships began speedily establishing links with previously unreachable world markets enabling private companies to develop to then-unheard of size and wealth. Following the Industrial Revolution perhaps a third of the worlds economic output is derived from manufacturing industriesmore than agricultures share.
Many developed countries and many developing/semi-developed countries depend significantly on industry. Industries the countries they reside in and the economies of those countries are interlinked in a complex web of interdependence.
