| Abstract: | In this paper, a basic input\|output model of price is established for the stability of price proper system, and a necessary and sufficient condition of the pricing stability is given. Also the expression formula of critical average gross profit rate is given. Meanwhile the quantitative influence of reducing direct consumption coefficients in the basic input\|output model of price on the critical average gross profit rate is studied. It is drawn out that critical average gross profit rate may be raised by reducing the direct consumption coefficients. Also the increase range of critical average gross profit rate is given. |
