Abstract:

Under the background of value chain division of labor, value-added trade accounting system can more accurately measure trade gains and embodied carbon emissions. Referring to this accounting system, this study used a multiregional input-output analysis method and a structural decomposition analysis model to calculate the economic benefits and implied carbon emissions of intraregional trade in Beijing Municipality, Tianjin Municipality, and Hebei Province, and compared their differences. The results show that: (1) The economic benefits obtained from intraregional trade are highest in Beijing, followed by Tianjin, and then Hebei, while the order of implied carbon emissions is the opposite; (2) Economic benefits of Beijing are highly concentrated in the services sector, while that of Tianjin and Hebei are in different sectors. Embodied CO2 emissions are concentrated in the middle trade sector, with the highest proportion in the energy sector; (3) The differences in economic benefits and carbon emissions obtained from trade between Beijing, Tianjin, and Hebei are mainly due to the intensity of complete CO2 emissions, trade scale, and trade structure. Therefore, in the process of integrated development, the Beijing-Tianjin-Hebei region should strengthen coordination and cooperation, jointly formulate carbon emission reduction targets, and assume responsibility for carbon emission reduction, and all regions should seek the best cooperation mode according to the development stage and characteristics.
