Abstract: This paper is based on two theoretical:one is industrial structure evolves endogenously and the other is that the evolution of consumption structure has regular relationship with families incomes.By empirically studying the pathway of some developed countries and analyzing the Input-output tables of China's economy,we analysis the impacts of consumption on industrial structure and forecast the evolution of industrial structure and the trend of CO₂ intensity.The results show:(1) The consumption scale and its structure is one of the main driving forces for China's industrial structure upgrading.(2) In order for CO₂ int ensity abatement,it is necessary to implement energy demand-side management and guide the people change to "low energy consumption,low carbon emission" life-style.

Key words: industrial structure optimization, carbon intensity, input-output analysis
