包容审慎监管是当前我国面对新经济业态发展提出的规制创新策略,具有极为深远的行政法治意义。面对科技发展与新经济业态的不确定性,包容审慎监管理念标志着现代行政法治的动态反思与演化趋势。从传统的规制理论角度观察,包容审慎监管的运行背后映射出回应性规制的执法策略、合作规制的运行范式以及规制试验主义的演进逻辑。包容审慎带有实质法治色彩的规制设计理念,有效运行不仅需要较为成熟的行政法治框架予以支撑,更需要现代行政国家的基础设施与行政能力予以辅助。在中国特色“发展型国家”的逻辑支配下,包容审慎监管的地方实践运行,往往较难实现包容与审慎之间的价值平衡,引发了一系列的监管困境与本土难题。包容审慎监管的中国图景也为理解规制与发展之间的二元关系提供了鲜活的制度样本。

“秒批”“无人审批”等自动化行政许可,成为当前我国优化营商环境改革实践的重要创新范式。自动化行政许可除了彰显出效能优势之外,还具有提升许可决策精准度与一致性、减少寻租空间等诸多治理价值。与此同时,自动化行政适用领域的渐次扩张带来更多的不确定性与风险,其对于数据汇聚共享的极高需求增加数据安全的风险系数,其采取的政企合作模式也增加了法律责任的认定难度。从制度完善角度,中央政府需要在自动化行政许可的政策试验过程中扮演更重要的枢纽角色,应坚持类型化思维,对自动化行政许可予以分类治理与扩展评估,努力实现自动化行政许可的数据汇聚共享与安全保障之间的平衡,进一步强化对智能审批系统政企合作模式的风险防控,修订《行政许可法》时应考虑增设专门的智能规范条款。
