This paper uses the interregional input-output model of 30 provinces to calculate China's provincial export implied carbon, and to decompose the historical change of China's export implied carbon from the provincial level. Influenced by the global financial crisis, China's export growth slowed in 2007-2010, and its scale effect on the implied carbon of China's exports was also relatively small, far below the pre-crisis level. Even during the worst of the global financial crisis, China's exports are still growing. Now, although the global economy is still not fully recovered from the financial crisis, it has improved markedly, and China's export implied carbon will continue to grow and even accelerate, so it is important to continue to focus on the impact of exports on China's carbon footprint. <<
