摘　　要：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 of exergy, combined with input-output based inventory calculation model, the cumulative exergy demand （CExD） of energy production in China was calculated. The CExD of different energy carriers was compared and the proportion of exergy consumed in high tier of production layers in CExD was analyzed. The results show that for 1 MJ of different energy, electricity has the largest CExD with 3.4 M J, followed by other secondary energy with 1.55 - 1.63 M J, and the CExD of primary fossil energy is the least with 1. 18 - 1.23 MJ. The results also show that input-output based inventory calculation model is more appropriate for the analysis of energy system than process based model.
