摘要
针对山东省未来20年内人口老龄化的变化趋势以及人口老龄化的影响因素等,分别构建灰色GM(1,1)、灰色关联度和主成分分析模型,使用SPSS、MATLAB软件编程求解,研究得到山东省未来20年内人口老龄化的趋势加快,人口密度和性别比是人口老龄化的主要影响因素等结论,并针对山东省人口老龄化问题提出一些建议。
Aiming at the changing trend of population aging and its influence factors in Shandong province over the next 20 years, grey GM ( 1,1 ), principal component analysis and grey correlation model are built, u- sing SPSS and MATLAB software to program, the research shows that the trend of population aging will accelerate in Shandong province over the next 20 years, the population density and ratio are the main factors influencing the aging of the population. Some reasonable suggestions are put forward for the population aging in Shandong prov- ince.
