以理论为基础,结合基于投入产出方法的清单计算模型,计算了我国能源生产的累计需求,对不同能源产品的累计需求进行了对比,并分析了高次生产的消耗在累计需求中的比例.结果表明:供应1 MJ的各能源产品,电力的累计需求最高,为3.4 MJ;其次为炼油产品、焦炭等其他二次能源,为1.55～1.63 MJ;初级化石能源最低,为1.18～1.23 MJ.与基于流程的清单计算模型相比,基于投入产出方法的清单计算模型更适用于分析能源系统.
Based on the theory and the inventory calculation model based on the input-output method, the accumulative demand of energy production in China is calculated, the accumulative demand of different energy products is compared, and the consumption of high-level production is accumulated The results show that the total demand of each energy product supplying 1 MJ is 3.4 MJ, followed by other secondary energy sources such as refined products and coke, which is 1.55-1.63 MJ, and the primary fossil energy is the lowest , 1.18 ~ 1.23 M. Compared with the process-based inventory calculation model, the inventory calculation model based on the input-output method is more suitable for the analysis of energy systems.
