摘要
本文在全面分析了煤炭消费与国民经济发展关系的基础上,采用定量分析的方法,对近期我国经济对煤炭的依赖程度和煤炭对国民经济的贡献率、吨煤经济效益进行了计算分析。研究结果表明:从过去20多年来看,我国经济发展对煤炭的依赖度并没有发生根本性的变化;"十一五"期间,我国煤炭生产和主要用煤行业对GDP总量和增量的总贡献率分别为15%和18%左右。
Based on a comprehensive analysis of the relationship between coal consumption and the development of national economy, by using the methods of quantitative analysis, this paper has specially focused on calculating of dependent index, contribution rate and tons of coal economic benefits between China＇s economic and coal development. The results show that the national economic dependent index of coal has not changed fundamentally in last two decades, and the contribution rates of coal to both annual GDP amount and annual GDP increase are about 15% and 18% respectively during the ＂Eleventh Five--Year＂ period （2005-2010）.
