【摘要】 煤炭是不可再生资源,是我国的基础能源和重要原料。但随着目前国际能源价格的大幅度波动,世界金融危机的严重影响,能源成为各国争抢的焦点。煤炭工业的发展状况直接影响到我国的世界地位,影响到我国社会主义现代化建设任务的顺利完成。随着中央规划建设13个国家级煤炭基地,提高煤炭产业集中度,提高煤炭生产和利用效率的重要战略部局调整,煤炭产业内的资源整合工作全面铺开。那么在相对分散的煤炭产业,特别是煤炭采选业是否存在内部联系较为紧密的、采用相同或相似战略的战略集团,以及各个企业如何识别自己所在的战略集团,如何确定自己的竞争地位,从而更好的制定企业的发展战略,解决这些问题将是我国煤炭资源整合以及煤炭企业发展面临的最重要的任务。本文以战略集团理论为基础,首先,选取中国神华等21个煤炭采选业上市公司做为研究样本,同时选取净资产收益率等13个财务指标做为战略变量,并搜集各上市公司2006年-2008年第三季度财务数据研究样本数据;其次,运用SPSS分析软件,通过因子分析确定公共因子数目,并运用主成分分析得到每个因子的主成分得分;第三,基于聚类算法,对主成分得分进行聚类运算,应用粗集知识将聚类结果引入粗集决策表做为决策属性集,对我国煤炭大型企业所处的战略集团进行识别研究,构建出相应的识别规则;最后,基于战略集团划分及识别规则提出我国煤炭产业各战略集团发展战略选择,并简要提出十条国家产业政策支持建议。更多还原

【Abstract】 Coal is the non-renewable resources and which is the basic energy and an important material. But with the fluctuations of the international energy price and the affected severely of the world financial crisis, the energy becomes the focus of international competition. As a big country of the energy production and consumption and a developing country put the main consumption target as coal, the development of coal industry affects directly our country’s status in the world and complete successfully the mission of our country’s socialist modernization. Resources integration of the coal industry in full swing with 13 national energy bases are constructed by central government and important indicator is put for improving the concentration of coal industry and improving the efficiency of coal production and use. In the relative dispersed coal industry, especially coal mining industry, is there strategy groups for more closely the internal contact and using the same or similar strategy, as well as how to identify various business strategies of their group and how to determine their competitive position in order to formulate business development strategies better, to solve these problems will be the most important task for China’s coal resources integration, as well as the development of coal enterprises.This article based on the theory of strategic groups, First, select 21 listed companies of coal industry such as China Shenhua as a sample, while select 13 financial indicators such as net assets income rate as strategic variable, and collect the third quarter financial data of the year of 2006-2008 for the listed companids.Second, use analysis software of SPSS, apply factor analysis to determine the number of public factors, and operation the principal component analysis get each factor score. Third, based on the clustering algorithm, get the clustering use principal component scores, application the knowledge of rough set to identify the strategy groups of the China’s coal office and build the identification rules. Finally, this article based on the divided and identification of strategy groups studies the coal enterprise development strategies of China’s listed company, and give ten recommendations of the national industrial policy.更多还原
