Abstract: By using the Box-Cox alternate form and the method of regression analysis,this paper engages in the quantitative analysis of the correlation between the future perstock profit and the quantitative indexes,such as the company growth flow,the rate of industrial growth and the variable coefficient of market share of the high technical listed companies.It also proposes an evaluation index number-the rate of marginal growth flow,which can evaluate the profitability of the high technical listed companies.The empirical studies show that given the present market price of the stock,the rate of marginal growth flow reflects the investment worth of the high technical listed companies scientifically,therefore is a very good evaluation index.

Key words: growth flow, regression analysis, Cox-Box alternate form, rate of industrial growth, rate of marginal growth flow
