| الملخص: | Against the backdrop of the global imperative to combat climate change, China, as one of the world's largest carbon emitters, plays a pivotal role in achieving the ''dual carbon'' goals through the low-carbon transformation of its industrial structure. This study employs input-output tables and energy consumption data from 2010 to 2020, applying input-output analysis and social network analysis to identify key industry sectors with high levels of embodied carbon emissions in China. It further examines the dynamic trends in the evolution of these sectors' carbon emissions. The study reveals that between 2010 and 2020, the sectors with the highest carbon emission intensity among China's 30 industries were electricity and heat production, petroleum, coal, and other fuel processing, as well as coal mining and washing. The flow of carbon emissions across sectors indicates that emissions from one sector to another traverse an average of 1.197 intermediary sectors, suggesting strong connections and robust network connectivity among neighboring sectors. Within the carbon emission network, sectors such as metal smelting and rolling processing, non-metallic mineral products, and coal mining and washing occupy significant positions and exert considerable influence on other sectors. The carbon emission patterns of these key sectors have undergone notable changes in recent years, primarily driven by technological advancements, policy adjustments, and shifts in market demand. The insights from this study not only enrich the existing body of literature but also highlight the significant technological progress and the ongoing low-carbon transformation of China's industrial structure, offering a new perspective for understanding the key nodes and evolution of China's industrial embodied carbon emission network.
