摘要
为了更好地反映煤矿安全综合发展状况,采用因子分析的方法,通过对山西省2008-2017年煤矿安全发展影响因素进行分析,通过研究得到两个主要公共因子:煤炭产量效益因子(f_1)、煤炭市场经济因子(f_2),其权重分别占比:61.65%、25.71%。通过对两个公共因子的线性组合,得出山西省煤矿安全发展综合得分,对煤矿安全发展状况定量化,清晰地反映了山西省实际煤矿安全发展状况,可以进一步为山西省煤矿安全发展的有关决策做出参考依据。
In order to better reflect the comprehensive development of coal mine safety,factor analysis method was used to analyze the influencing factors of coal mine safety development in Shanxi Province from 2008 to 2017. Two main public factors were obtained through the study: coal output benefit factor (f1),coal market economy factor (f2 ),and their weights accounted for 61. 65% and 25. 71% respectively. Through the linear combination of the two public factors,the comprehensive score of coal mine safety development in Shanxi Province is obtained. The quantification of and the coal mine safety development status clearly reflects the actual coal mine safety development status in Shanxi Province,and further provides reference for the relevant decisionmaking of coal mine safety development in Shanxi Province.
