计划生育新政策对深圳市人口数量的影响

THE INFLUENCE OF NEW ONE-CHILD' S POLICY ON SHENZHEN'S POPULATION

本文利用主成分分析法(PCA)挖掘影响人口内部规律的4个主要因素并以此作为约束条件,利用支持向量机(SVM)算法建立PCA-SVM模型对深圳市未来人口数量进行预测,并讨论了计划生育新政策对其未来人口数量的影响。

In this paper,we take the four main factors affected by internal principles of population as model constraints,within Principle Components Analysis( PCA) algorithm. Establish a PCA-SVM model by Support Vector Machine( SVM) algorithm,and predicting the population size of Shenzhen city,discussing the influence of new one-child' s policy on that in the near future.
