With the burgeoning global concern over climate change, nations around the world are vigorously embracing the low-carbon economy. As the primary exporter of automobiles, China faces significant carbon emissions, a factor that substantially diminishes its product competitiveness in the international market and hampers efforts towards sustainable environmental development. This research paper focuses on discussing the impact of a low-carbon economy on the international competitiveness of Chinas automobile export. Through qualitative analysis, the study primarily reviews existing literature, highlighting the crucial roles played by technology factors, demand structure, and capital in shaping the industrys international competitiveness. This paper finds an inverse correlation between the average fuel consumption and Chinas automobile industrys revealed comparative advantage. This suggests that fostering a low-carbon economy could potentially enhance international competitiveness in global trade. The findings of this research hold significant implications for policy makers that they can utilize this knowledge to formulate strategies aimed at reducing carbon emissions. Hence, it propels the progression of a low-carbon economy and elevates the worldwide prestige of China's automobile industry.
