Abstract: In this paper, through founding a theoretical mathematics model we derive the sufficient-necessary condition of raising interest promoting economic growth in a general theoretical framework and forecast the important effect of consumer’s habitude, macroeconomics stability and capital market perfect on financial deepening reform. At the same time, this paper also predicts the possibility of exist of economic multiple equilibrium from a new perspective.
