Abstract:

The changes of global climate abnormality induced by greenhouse gases are the focuses of the world’s attention, CO2 emissions induced by energy consumptions has been the major greenhouse gas during recent years. In order to show mechanism of industrial structure of Chinese energy consumption, we bring forward the concept of average energy consumption and construct an AECPC(Average Energy Consumptions of Production Chains) model based on input-output technique in this paper, which not only reflects direct energy consumption and indirect energy consumption of each sector, but also reflects the effect on energy consumption by different production links from the point of view of energy saving. By applying the model, the paper calculates twenty-nine sectors in Chinese national economy in 2005. The results show maximal average consumptions of production chains of nine kinds of energy production respectively. These production chains not only include known sectors which are high energy consumption, but also other sector, such as the production and supply of tap water sector. The AECPC model can help make industrial policy of Chinese industrial transformation impact on carbon emissions.

Key words: average energy consumption, average energy consumptions of production chains model, direct energy consumption, industrial transformation； China, production chain, production link, total energy consumption
