Logistic方程模型常用于描述一般发展系统的演化过程。用NLS方法估计模型参数,以建筑业总产值作为状态变量对我国建筑业产业系统演化过程进行了实证分析。结果显示,建筑产业系统演化过程遵循Logistic方程曲线。
Logistic equation models are often used to describe the evolution of a general development system. NLS method is used to estimate the model parameters, and the total output value of construction industry is used as a state variable to empirically analyze the system evolution of China's construction industry. The results show that the evolution of the building industry system follows the curve of Logistic equation.
