With the continuous growth of the economy, the contradiction between finance and the environment has become increasingly prominent, and green finance has attracted much attention due to its sustainable development function. This study integrates green financial efficiency into green total factor productivity based on the two-stage super efficiency unexpected SBM model, and constructs the financial green total factor productivity of the Yangtze River Economic Belt from 2013 to 2021. The convergence model is used to verify the convergence of productivity development. The research results indicate that, in terms of time dimension, the efficiency of green finance in the Yangtze River Economic Belt is relatively stable, the level of financial ecological performance first decreases and then increases, and the financial feedback ecological performance remains at a high level for a long time. The overall trend of financial green total factors is increasing, and financial green technology innovation is an important driving factor for the increase; In terms of convergence testing, no significant alpha convergence was found in the upper, middle, and lower reaches of the Yangtze River Economic Belt, and the regional differences did not significantly decrease. However, there was overall beta convergence, indicating a "catch-up effect" from low productivity provinces to high productivity provinces.
