Abstract: This study examines the impact of public data openness on environmental welfare performance using a quasi-natural experimental approach based on the establishment of prefecture-level city public data openness platforms. Our findings reveal that public data openness significantly improves urban environmental welfare performance. Furthermore, heterogeneity analysis highlights that public data openness can play a more positive role in cities in eastern China, cities with greater fiscal autonomy, and cities where local governments place greater emphasis on environmental protection. Mechanism analysis demonstrates that public data openness enhances environmental welfare performance through stricter environmental regulatory constraints, industrial structure upgrading, increased public participation and supervision, and advancements in innovation and entrepreneurship. Extensive analysis shows that public data openness within a spatial framework can significantly enhance environmental welfare performance in the region. However, this process will generate a triple “siphon effect” that inhibits improvements in urban environmental welfare performance in surrounding areas. Additionally, this effect exhibits a certain degree of geographical attenuation influenced by economic interdependence, with an attenuation boundary of 1000 km. This study injects internet and big data thinking into ecological civilization construction, endowing it with new models, new scenarios, and new momentum, and providing a brand-new approach to sustainable development practices.
