摘要

本文分析了1991年以来中国煤炭消费的变化,以及煤炭消费占总能源消费比重的变化。认为电力、钢铁、建材、化工是四大煤炭消费行业,占2005年煤炭消费总量的85%。考虑到这四个行业的能源消费构成特征、煤炭需求的主要决定因素、未来能效提升的潜力、结构变化等因素,本文对这四个行业2010年和2020年的国内煤炭需求进行了预测。此外,考虑到我国未来经济增长率和节能目标等相关因素,运用单位GDP能耗法和能源弹性系数法对未来能源需求进行预测。然后,参考其他机构对未来一次能源需求(不包括一次煤炭需求)的预测结果,对2010年和2020年的煤炭需求进行了间接预测。经过两种方法的结果对比,认为2010年煤炭需求可能在2620-2850万吨,2020年可能在3090-3490万吨,其中发电用煤仍然是煤炭需求增长的驱动力。

China's Present Situation of Coal Consumption and Future Coal Demand Forecast

This article analyzes China's coal consumption changes since 1991 and proportion change of coal consumption to total energy consumption. It is argued that power, iron and steel, construction material, and chemical industries are the four major coal consumption industries, which account for 85% of total coal consumption in 2005. Considering energy consumption composition characteristics of these four industries, major coal demand determinants, potentials of future energy efficiency improvement, and structural changes, etc., this article makes a forecast of 2010s and 2020s domestic coal demand in these four industries. In addition, considering such relevant factors as our country's future economic growth rate and energy saving target, it forecasts future energy demands, using per unit GDP energy consumption method and energy elasticity coefficient method as well. Then it uses other institution's results about future primary energy demand, excluding primary coal demand, for reference, and forecasts coal demands in 2010 and 2020 indirectly. After results comparison between these two methods, it is believed that coal demands in 2010 might be 2620–2850 million tons and in 2020 might be 3090–3490 million tons, in which, coal used in power generation is still the driven force of coal demand growth.
