| Primary sector of industry: |
|
Primary industry is found in larger amounts in developing
countries; for instance, animal husbandry is more common in
Africa than in Japan. The primary sector of industry generally
involves the changing process of natural resources into primary
products. Most products from this sector are considered raw
materials for other industries. Major businesses in this sector
include agriculture, agribusiness, fishing, forestry and all
mining and quarrying industries.The manufacturing industries
that aggregate, pack, package, purify or process the raw materials
close to the primary producers are normally considered part
of this sector, especially if the raw material is unsuitable
for sale or difficult to transport long distances. However
in developed countries primary industry becomes more developed
and more high-tech, for instance the mechanization of arable
farming opposed to hand picking and planting. In America in
the corn belt combine harvesters pick the corn, spray systems
distribute large amounts of pesticides, herbicides and fungicides
thus proving that the more developed an economy is, the higher
the capital that is invested into expansion is. These technological
advances and investment allow the primary sector to require
less workforce and, this way, developed countries tend to
have a smaller percentage of their workforce involved in primary
activities.

| Secondary
sector of industry : |
The secondary sector of industry includes
those economic sectors that create a finished,
usable product: manufacturing and construction.
This sector of industry generally takes the
output of the primary sector and manufactures
finished goods or products to a point where
they are suitable for use by other businesses,
for export, or sale to domestic consumers.
This sector is often divided into light industry
and heavy industry. Many of these industries
consume large quantities of energy and require
factories and machinery to convert the raw
materials into goods and products. They also
produce waste materials and waste heat that
may pose environmental problems or cause pollution.
Some economists contrast wealth producing
sectors in an economy such as manufacturing
with the service sector which tends to be
wealth consuming. Examples of service may
include retail, insurance, and government.
These economists contend that an economy
begins to decline as its wealth producing
sector shrinks. Manufacturing is an important
activity to promote economic growth and
development. Nations which export manufactured
products tend to generate higher marginal
GDP growth which supports higher incomes
and marginal tax revenue needed to fund
the quality of life initiatives such as
health care and infrastructure in the economy.
The field is an important source for engineering
job opportunities. Among developed countries,

| Tertiary sector of industry: |
Historically certain manufacturing industries have
gone into a decline due to various economic factors,
including the development of replacement technology
or the loss of competitive advantage. An example of
the former is the decline in carriage manufacturing
when the automobile was mass-produced.
A recent trend has been
the migration of prosperous, industrialized nations
toward a post-industrial society. This is manifested
by an increase in the service sector at the expense
of manufacturing, and the development of an information-based
economy, the so-called informational revolution. In
a post-industrial society, manufacturing is relocated
to more economically-favorable locations through a
process of offshoring |

| Quaternary sector
of industry: |
Quaternary sector of industry is the sector of industry
including the intellectual services - research, development,
and information. It was once considered part of the
tertiary sector of industry. This includes the high
technology industry, with information and communication
technology and some forms of scientific research,
as well as education and consulting, and information
industry.
The quaternary sector can be seen
as the sector in which companies invest in order
to ensure further expansion. Research will be directed
into cutting costs, tapping into markets, producing
innovative ideas, new production methods and methods
of manufacture, amongst others. To many industries,
such as pharmaceutical giants such as Pfizer, the
sector is the most valuable because it creates future
branded products which the company will profit from.
According to some definitions, the quaternary sector
also includes all other pure services, such as the
entertainment industry. There is also the notion
of a "quinary sector" which would encompass
health, education, culture and research.
