Abstract: Beijing has experienced rapid development in autonomous driving industry, yet lacks supporting local legislation. Examining Beijing's policy framework in autonomous driving since 2015 reveals its pioneering role in policy implementation, promoting cross-regional collaboration, developing multi-scenario deployments, and emphasizing data security. While national legislation remains premature, local legislative pilots can accumulate valuable experience to inform national lawmaking. Additionally, local legislation can mediate the tension between technological advancement and legal stability, fostering autonomous vehicle industry development through regulatory competition. Analysis of existing local legislative models nationwide reveals three patterns: special economic zone legislation, promotional legislation, and local traffic law amendments, all addressing access requirements, entity responsibilities, data governance, and application scenarios. Beijing is better suited to adopt specialized autonomous vehicle legislation, focusing on challenging issues including vehicle access, insurance, and traffic accident liability. The distinctive features of Beijing's autonomous vehicle legislation include clear administrative authority, promotion of Beijing-Tianjin-Hebei coordination, effective utilization of technological advantages, development of supporting infrastructure, and strong emphasis on data security.
