摘要
依据中国城镇化水平曲线变化的特点,在经典的Logistic模型基础上,设计相对增长率函数,建立改进的Logistic模型应用于中国城镇化水平的预测.研究结果表明,预测结果同经典Logistic模型和双S曲线模型相比,拟合程度更高,其预测值可为相应决策部门制定政策提供参考.
According to the characteristics of China's urbanization rate curve,based on the classical Logistic model,the relative growth rate function is designed,and an improved Logistic model is established to predict the level of urbanization in China.The results show that the fitting degree of the prediction results is higher than that of the classical Logistic model and the known double S curve model,and its prediction value can provide a reference for the corresponding decision-making departments to formulate policies.
