Answer:
Basic industry.
Explanation:
In economics, a basic industry is a type of industry which is oriented towards exporting most of its production. Basic industries for the most part sell their products primarily to consumers outside a settlement, as generally speaking they're not meant for direct use by most consumers, but form part of a larger value chain where their production is then transformed into other products. Basic industries are considered highly important: because of their export orientation, the money coming from outside or abroad strengthens the local economy and creates jobs; and also, they tend to be very large firms with huge resources and capital. Examples of basic industries include mining and steel.
