Abstract: Yangtze River Economic Belt(YEB) has a major mission to take the lead in achieving the “Dural Carbon” target, and it is urgent to accurately identify the pressure of reducing emissions and increasing sinks in YEB and its disequilibrium characteristics. Based on the calculation of carbon emission and carbon sink data of 336 prefecture-level and above cities in China from 2000 to 2019, this paper constructs an index of “city carbon footprint pressure” to identify the pressure of reducing emissions and increasing sinks of cities in YEB in a national perspective, and study its characteristics of regional differences, distribution dynamics and spatial agglomeration using Dagum Gini coefficient, kernel density estimation and local Moran index, respectively, to explore its disequilibrium from multiple dimensions. The results show that: (1) the carbon footprint pressure of cities in YEB is lower than that of both regions outside YEB and the national average. There are obvious differences between the upper, middle and lower reaches, showing a spatial pattern with gradient increasing. (2) From the perspective of regional differences, the overall difference is large and tends to expand. The difference decomposition shows that the net difference between regions is the main source of the overall difference, and it is mainly caused by the difference between upper and lower reaches. (3) From the perspective of distribution dynamics, the absolute differences is large, while there are obvious multi-polar differentiation characteristics. (4) From the perspective of spatial agglomeration, there are four types of spatial agglomeration. The upper and middle reaches of YEB are dominated by low-low spatial agglomeration, and the lower reaches of YEB is dominated by high-high spatial agglomeration.
