This paper has established one new pattern to study economic growth from industrial organization with industrial organization theory, investment theory and economic growth theory. From the view of firm, the study finds that investment expenditure changes with firm number. The investment expenditure of single firm fall with increase of firm number and the investment expenditure increase with fall of firm number. From the view of industry, the relation depends on the demand elasticity of price. When elasticity is greater, the industrial investment expenditure also increases with the firm number increase. When elasticity is less, along with the increase of firm number, the industrial investment expenditure goes up first promptly, and then slows to drop.
