Green low-carbon development is the only way to achieve carbon peaking and carbon neutrality. The green total factor productivity and carbon productivity of Beijing，Tianjin and Hebei are measured separately，and compared with those of Beijing，Tianjin and Hebei，the Yangtze River Delta and the Pearl River Delta，and the results show that the green low-carbon development of Beijing，Tianjin and Hebei is higher，Tianjin is second and Hebei is lower；the green low-carbon development of the Pearl River Delta is higher，the Yangtze River Delta is second and Beijing，Tianjin and Hebei is lower. The economic growth mode is determined by the contribution rate of carbon productivity growth to economic growth，and the growth mode of Beijing-Tianjin-Hebei region gradually improved during the period from the Tenth Five-Year Plan to the Twelfth Five-Year Plan. The economic growth mode is high-carbon type II in the 13th Five-Year Plan period. The motives of green and low-carbon development in Beijing，Tianjin and Hebei are analyzed from the perspectives of industrial structure，energy structure and technological innovation respectively.
