Abstract: Based on the input-output model and structural decomposition analysis (SDA), a cross-sectoral decomposition framework was constructed, which included carbon emission coefficients, energy structure, energy efficiency, internal production linkage, external production linkage, internal final demand, and external final demand, to reveal the driving effects of carbon emission disparities among China's industrial sectors from 2012 to 2020. The results indicated that the growth rate of carbon emissions in China's industrial sectors slowed down, while structural contradictions became prominent. The four sectors with the highest carbon emissions were the gas and water supply industry, metal and non-metal products industry, transportation, storage and postal industry, and chemical industry, suggesting that promoting green transformation in these sectors was crucial for achieving overall carbon emission reduction goals.Internal production linkage and external production linkage effects exhibited significant heterogeneity. The carbon emissions driven by the internal production linkage effect in the mining industry were lower than those in the equipment manufacturing industry, while the carbon emissions driven by the external production linkage effect in the chemical industry were higher than those in the equipment manufacturing industry, creating a “low-carbon island-high-carbon network” dilemma. Although the internal final demand effect in the mining industry demonstrated potential for carbon emission reduction, the external final demand effect significantly undermined this advantage, revealing shortcomings in cross-sectoral synergistic governance and difficulties in breaking the “high-carbon lock-in”.Based on these findings, the Chinese government should fully incorporate high-emission sectors into the carbon trading market and establish an effective cross-sectoral synergistic governance mechanism. Win-win outcomes for economic development and carbon emission reduction could be achieved through responsibility linkage and technology sharing within industrial chains.
