For firms' adoption behavior, this thesis firstly explains why firms' adoption is in order from the static state by analyzing the regular pattern of firms' adoption behavior; builds control model of firms' adoption decision behavior, and describes the relationship between the stable values of response probability of firms' adoption decision; secondly raises the conception of firms' states from the dynamic state and defines two state variables to explain why and how a firm changes from nonadoption to adoption through the dynamic analysis of the factors influencing the two state variables. Thirdly, constructs the functions of adopting and choosing behavior with mathematical method, which is verified in following.
