基于主成分分析的十省(区)煤炭工业竞争力分析

Analysis of Coal Industrial Competitiveness of Ten Provinces(Areas) Based on Principal Component Analysis

基于产业规模、产业经营、产业效益、产业能耗及安全4个维度,建立了省(区)煤炭工业竞争力评价指标体系,运用主成分分析法,对内蒙古等10个省(区)煤炭工业竞争力水平进行了评价,得出内蒙古、山西、陕西三省位于煤炭工业竞争力前三,山东、河南和河北位于第4至第6位,安徽、云南、新疆和黑龙江位于第7至第10位。总体上看,煤炭工业竞争力与各省煤炭资源优势和煤炭产量的关系较大。

The coal industrial competitiveness evaluation index system of provinces（areas） is established based on four dimensions, which are the industrial scale, the industrial management, the industrial benefits, the industrial energy consumption and safety. And the coal industrial competitiveness of ten provinces（areas） including Inner Mongolia etc. is analyzed by principal component analysis. Displaying that Inner Mongolia, Shanxi and Shaanxi Province are situated in the top of three. Shandong, Henan and Hebei Province are situated in the forth to sixth. Anhui, Yunnan, Xinjiang and Heilongjiang Province are situated in the seventh to tenth. Overall, the coal industry competitiveness has a more important relationship with the advantages of provinces’ coal resources and the output of coal.
