摘要
In an open economy,embodied carbon dioxide emissions in international trade should be taken into consideration to scientifically define each country's emissions responsibility.In this study,a multiregional input-output model is constructed to calculate the embodied carbon dioxide emissions of 25 World Trade Organization members,including China,according to the producer-consumer shared responsibility principle.The study indicates that:it is fairer and more efficient to identify each country's carbon dioxide emissions responsibility according to the shared responsibility principle;China's producer responsibility is 1.4 times that of the USA,while China's consumer responsibility is only one-tenth that of the USA;according to the producer responsibility principle,China shoulders the greatest responsibility.According to the producerconsumer shared responsibility principle,China's responsibility shows a large decrease.Resource endowment,economic development stage,and trade structure account for the abovementioned changes in China's emissions responsibility.
