Shahnam said:my logic is based on the definition of commerce. for what I've studied Commerce provides "aids to trade" while trading itself is part of production together with commerce. So, definitely trade increases specialization but commerce would be providing the ancillary activities which may include promotion and marketing. Therefore, commerce would help to find the market for the products.
And I'm not sure about this road and pipeline wala question so no comments on that.
Well i dont think it will help find market. If you improve your tranportation system by building roads, airports etc
it will help you REACH market not FIND market. By market he means consumers. what do you suggest
