- With the intensification of global warming and continued growth in energy consumption, China is facing increasing pressure to cut its CO₂ (carbon dioxide) emissions down. This paper discusses the driving forces influencing China's CO₂ emissions based on Path–STIRPAT model—a method combining Path analysis with STIRPAT (stochastic impacts by regression on population, affluence and technology) model. The analysis shows that GDP per capita (A), industrial structure (IS), population (P), urbanization level (R) and technology level (T) are the main factors influencing China's CO₂ emissions, which exert an influence interactively and collaboratively. The sequence of the size of factors' direct influence on China's CO₂ emission is A>T>P>R>IS, while that of factors' total influence is A>R>P>T>IS. One percent increase in A, IS, P, R and T leads to 0.44, 1.58, 1.31, 1.12 and −1.09 percentage change in CO₂ emission totally, where their direct contribution is 0.45, 0.07, 0.63, 0.08, 0.92, respectively. Improving T is the most important way for CO₂ reduction in China.
