Ineconomics, thesecondary sector is theeconomic sector which comprisesmanufacturing, encompassingindustries thatproduce a finished, usableproduct or are involved inconstruction.
This sector generally takes the output of theprimary sector (i.e.raw materials like metals, wood) and createsfinished goods suitable for sale to domesticbusinesses orconsumers and forexport (via distribution through thetertiary sector). Many of these industries consume large quantities of energy, requirefactories and use machinery; they are often classified aslight orheavy based on such quantities. This also produceswaste materials andwaste heat that may cause environmental problems orpollution (seenegative externalities). Examples includetextile production,car manufacturing, andhandicraft.[1]
Manufacturing is an important activity in promotingeconomic growth anddevelopment. Nations that export manufactured products tend to generate higher marginalGDP growth, which supports higherincomes and therefore marginaltax revenue needed to fund such government expenditures ashealth care andinfrastructure. Amongdeveloped countries, it is an important source of well-paying jobs for themiddle class (e.g., engineering) to facilitate greatersocial mobility for successive generations on the economy. Currently,[when?] an estimated 20% of thelabor force in the United States is involved in the secondary industry.[2]
The secondary sector depends on the primary sector for the raw materials necessary for production. Countries that primarily produceagricultural and other raw materials. The value added through the transformation of raw materials into finished goods reliably generates greaterprofitability, which underlies the faster growth ofdeveloped economies.
