查询词典 conception control

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.

对于企业采用行为，首先从静态角度剖析了企业采用行为的一般机理用以说明为什么各企业在采用技术创新上有先有后，并建立了企业采用决策行为模型，定量刻画企业采用决策响应概率与动力结构的关系；其次从动态角度提出了企业状态演变概念并定义了两个状态变量，通过对两个状态变量的影响因素分析和动态分析，用以说明某一企业为什么和如何实现由未采用者到采用者的转变；第三对企业采用行为进行定量形式化构造了采用效果函数及选择概率函数等，并得到了调查结果的支持。
