The equilibrium price and the price plasticity of stock are introduced according to the price - volume laws of stock and the plasticity theory in mechanics. A stock price plasticity model based on price and volume is established by econometrical methods to analyze the theory of plasticity of stock price, and the parameter in the model is estimated and tested. The results reveal that the coefficient of stock price plasticity is in positive proportion to the amount of locked current stock. By this result the locked current stock can be recoginized through comparing the coefficient of stock price plasticity in different period.
