The importance of trade and commerce are mentioned in following points :-
1. Commerce tries to satisfy increasing human wants
Human wants are never ending. They can be classified as 'Basic wants' and 'Secondary wants'. Commerce has made distribution and movement of goods possible from one part of the world to the other. Today we can buy anything produced anywhere in the world. This has in turn enabled man to satisfy his innumerable wants and thereby promoting social welfare.
2. Commerce helps to increase our standard of living
Standard of living refers to quality of life enjoyed by the members of a society. When man consumes more products his standard of living improves. To consume a variety of goods he must be able to secure them first. Commerce helps us to get what we want at right time, right place and at right price and thus helps in improving our standard of living.
3. Commerce links producers and consumers
Production is meant for ultimate consumption. Commerce makes possible to link producers and consumers through retailers and wholesalers and also through the aids to trade. Consumers get information about different goods through advertisements and salesmanship. The manufacturers are regularly informed about the likes and dislikes of the consumers through marketing research. Thus commerce creates contact between the centers of production and consumption and links them.
4. Commerce generates employment opportunities
The growth of commerce, industry and trade bring about the growth of agencies of trade such as banking, transport, warehousing, advertising, etc. These agencies need people to look after their functioning. Increase in production results in increasing demand, which further results in boosting employment opportunities. Thus development of commerce generates more and more employment opportunities for millions of people in a country.
