Abstract: Green finance has the function of resource allocation and risk management, and should therefore play an important role in the low-carbon transformation of high-energy-consumption industries. Based on the traditional principles of fairness and efficiency, this paper incorporates the principle of green finance to construct a carbon emission reduction responsibility allocation index system for China's high-energy-consumption industries. Using the entropy weight TOPSIS method and carbon emission reduction volume calculation model, it quantifies China's high-energy-consumption industries' carbon emission reduction responsibility targets based on the goal of a 65% reduction in carbon intensity compared to 2005 by 2030. And, based on an analysis of the degree of linkage between green finance and carbon emission reduction core tasks, it proposes differentiated carbon emission reduction strategies for high-energy-consumption industries. The results show that high-energy-consumption industries bear 50.03% of China's carbon emission reduction responsibility, and there are significant differences in carbon emission reduction responsibility within the industry. Green finance has a significant impact on carbon emission reduction responsibility allocation, with the weight of influence exceeding 40%. Green credit has a high degree of linkage with the core task of carbon emission reduction, and can effectively guide resource allocation and alleviate the risks of low-carbon transformation under a differentiated carbon emission reduction strategy.
