Abstract:

Coal is a major energy resource in China. Coal industry is a leading industry in those provinces abundant in coal, but is imbalanced in development. This paper, from Xinjiang, Inner Mongolia, Shanxi and Shaanxi, applies PCA to establish an index system composing of 4 factors and 11 indexes at actual competitiveness level and at potential competitiveness level, uses SPSS 16.0 software to process relevant data and works out their competitiveness index and rank that in actual competitiveness level, Shanxi ranks top, then Inner Mongolia, Xinjiang and Shaanxi. Xinjiang ranks first at potential competitiveness level. This paper presents suggestions in clustering development and collaborative construction in coal industry.

Key words: coal industry, PCA, competitiveness, case study

摘要：

煤炭资源是我国经济发展中的主体能源，煤炭产业是煤炭资源丰富省区的主导产业，但煤炭产业的发展存在着不平衡性，以全国煤炭资源储量前四位的新疆、内蒙古、山西、陕西四省为研究对象，运用主成分分析法，从现实竞争力和潜在竞争力2个层面构建了由4因素11个指标组成的指标体系，在此基础上运用SPSS16.0软件对相关数据进行整理分析，最终得出了四省区煤炭产业的竞争力指数和竞争力排名，即山西最具现实竞争力，其次是内蒙古、新疆和陕西。同时新疆是最具潜在竞争力的省份，基于此，提出了煤炭产业集群化发展及四省区协同共建的产业发展建议。
