Research on Industry and Carbon Emission Gradient Under the Background of Carbon Emission Peak in the Beijing-Tianjin-Hebei Region

Through the Index Decomposition Analysis method of spatial perspective, this paper analyzes the characteristics of the industrial and Carbon Emission Gradient of subdivided industries and studies the interaction between the Beijing-Tianjin-Hebei region Industrial Development and carbon emission by using the correlation coefficient matrix of Industrial Gradient and Carbon Emission Gradient. The results show that the relative carbon emission intensity in some high-end manufacturing regions in Beijing is prominent, and the Carbon Emission Gradient still has room to decline; Tianjin's overall carbon emission efficiency is relatively low, offsetting the decline in carbon emission intensity caused by the increase of capital productivity; Hebei is affected by the siphoning effect of Beijing, and the negative impact of labor productivity on carbon emission efficiency is more significant, but it shows the characteristics of low-carbon transfer when undertaking high pollution and high carbon emission industries. Finally, based on the above conclusions, the paper proposes to put forward targeted carbon emission reduction countermeasures and suggestions for the “Carbon Emission Peak” with coordination of the region from three perspectives: the transformation of high-end manufacturing industry, scientific and technological innovation, and promoting the flow of production factors.
