Digital transformation has a positive impact on corporate sustainability performance. Based on the data of listed enterprises from 2013 to 2023, this paper uses Python technology to build enterprise digital transformation indicators, and uses the combination of financial performance and environmental and social responsibility performance to measure enterprise sustainable development performance in a more comprehensive and scientific way. From the theoretical level to the empirical level, this paper deeply discusses how digital transformation can improve the sustainable development performance of manufacturing enterprises. The following conclusions are drawn: (1) Digital transformation significantly improves the financial performance and environmental and social responsibility performance of enterprises, thus improving the sustainable development performance of enterprises.
