Concept:The origin of commerce is linked to the fundamental need to move goods from producers to consumers.
Explanation:Commerce includes all activities that help in the exchange of goods and services.
These activities began when people realised that goods produced in one place had to be made available in other places.
This requirement to transfer and supply goods is called distribution.
Without distribution, buying and selling cannot take place on a large scale.
Therefore, commerce arose mainly because of the need for distribution.
Other factors like competition, privatization, and specialization came later with economic development.
Thus, distribution is the root cause behind the start of commerce.
