Q.Explain the interdependence of Industry, Commerce, and Trade with a suitable example.

Industry, Commerce, and Trade form one continuous chain — each stage depends on the one before it and the one after it, so removing any single link breaks the whole chain.

How Industry depends on Commerce: a factory earns nothing merely by manufacturing goods — it earns revenue only once those goods are actually sold. Commerce (through Trade) finds the buyers and completes the sale, and Commerce's Auxiliaries (transport, warehousing, banking, insurance) make that sale physically and financially possible. Without Commerce, a factory's output would simply pile up unsold.

How Commerce depends on Industry: Trade has nothing to buy or sell unless Industry has produced it first. A wholesaler's or retailer's entire business exists only because Industry continuously supplies fresh goods to trade in.

How Trade depends on the Aids to Trade: even Trade cannot function as pure buying-and-selling in isolation — a wholesaler cannot buy in bulk without banking finance, goods cannot reach a distant retailer without transportation, seasonal produce cannot be sold year-round without warehousing, a shipment cannot be safely risked without insurance, and a buyer will never order a product they never heard of without advertising. …
