“煤炭为主体,电力为中心”是中国能源工业发展的基本方针。近年来由于受资源限制和国民经济快速发展的影响,煤炭价格不断上涨,大部分煤炭企业利润大增,而依靠煤发电的火电企业收入和利润却逐渐减少。从而引发了煤、电之争和煤、电价格联动方案的出台。为了真实反映我国煤、电企业经营业绩的现实情况,本文将从数理统计学的角度,利用主成份分析方法对现有煤炭上市公司财务指标进行经营业绩综合评价研究。针对实证分析结果,本文将提出努力提高电力企业经营绩效进而缓解煤电紧张关系的政策建议。
“Coal as the mainstay, power as the center ” is the basic principle of China’s energy industry development. In recent years, due to resource constraints and the rapid development of the national economy, the price of coal has been on the rise. The profits of most coal enterprises have risen sharply. However, the revenue and profits of coal-fired power plants have been decreasing. Which led to the coal, electricity and coal, electricity price linkage program introduced. In order to truly reflect the actual situation of the business performance of coal and electricity enterprises in our country, this paper will use the principal component analysis method to make a comprehensive evaluation of the financial performance of the existing coal listed companies from the perspective of mathematical statistics. In view of the result of empirical analysis, this article will put forward the policy suggestion of making efforts to improve the operation performance of power enterprises and then to relieve the tension of coal power.
