Research of Level of Social Security based on PCA

摘要

Social security system, as a social stabilizer, plays a very important role in adjusting the social income distribution, narrowing the gap between the rich and the poor, and maintaining social fairness and justice. Based on connotations of social security and regional comparisons, an index system is constructed for evaluating development and level of social security, which is mainly evaluated and measured by principal components analysis. At last, main factors that impact development and level of social security are analyzed.
