The revision of The Administrative Reconsideration Law has been officially launched in 2020. The theoretical and practical circles of administrative law have conducted extensive and in-depth discussions on many issues affecting the development of administrative reconsideration，including the nature，function，the “double accused” system and reform of the reconsideration system，which laid the foundation for the revision and improvement of The Administrative Reconsideration Law. The big data in the twenty years since the implementation of The Administrative Reconsideration Law also shows that administrative reconsideration is increasingly playing an important role in resolving administrative disputes. The reform of the administrative reconsideration system and mechanism has achieved remarkable results，and relevant content should also be reflected in the amendment of the law. This report aims to record the annual progress of administrative reconsideration，focusing on the three dimensions of theoretical research，system development and practical exploration，and hopes to provide theoretical explanations for the ideal picture of administrative reconsideration through the annual inventory of administrative reconsideration.
