【摘要】 人口问题一直是制约和影响我国可持续发展的关键因素之一。影响人口系统变化的因素众多,这些因素之间的结构关系难以准确描述,它们对人口变化的作用更是无法精确计算。可见,人口系统是一个信息不完全的典型灰色系统。运用灰色系统GM(1,1)模型建立我国人口发展的灰色动态模型,通过检验和残差分析,本文对我国建国以来人口发展的态势与周期变化作了科学划分,为预测我国人口未来发展的趋势,制定合理的人口政策和人口规划提供科学的依据。更多还原

【Abstract】 The population problem is one of the key factors that has been restricted and influenced the sustainable development of China. There are many factors affecting the change of population system. The structural relationships between these factors are difficult to be described exactly and their functions in population changes are not calculated accurately. Therefore the population system is a typical grey system with incomplete information. We establish grey dynamic model of population development according to the GM(1,1) model and make division of the developments in trend and cycle since 1949 by the test and the analysis of residual error. A scientific basis is provided for forecasting the trend of population development and making rational population policy and plan更多还原
