The digital economy, as the most active area in China’s economic development, is an important engine for fuelling the high-quality development of China’s economy. What impact will the digital economy have on low carbon development while promoting economic innovation and development. This paper takes the data of 90 prefecture-level cities in the Yangtze River Economic Belt as a research sample to explore the effect of digital economy on carbon emissions in the Yangtze River Economic Belt. The empirical results show that there is an inverted U-shaped non-linear relationship between the impact of the digital economy on carbon emissions in the Yangtze River Economic Belt, and that the digital economy will have an indirect effect on carbon emissions through the industrial structure upgrading, and there is also heterogeneity in the upstream, midstream and downstream regions. Based on the above conclusions, the Yangtze River Economic Belt should strengthen the cooperation and coordination between the digital economy and green low-carbon development when developing the digital economy, and jointly promote the regional green low-carbon transformation, and also focus on the implementation of differentiated policy guidance to promote the achievement of carbon emission reduction goals. %K 数字经济， %K 绿色低碳， %K 倒U型曲线
