“接诉即办”机制作为中国社会治理现代化的重要创新，通过构建全时响应、高效办理的诉求回应体系，为"共建共治共享"社会治理格局的落地提供了关键支撑。本文聚焦于近年来的创新实践，分析该机制如何通过数字化与智能化升级、治理流程再造以及多元协同平台构建，推动治理模式从被动响应转向主动治理。研究表明，接诉即办不仅是解决民生问题的渠道，更是撬动治理结构变革、培育社会治理共同体的战略支点，其创新实践为超大城市和基层治理现代化提供了可复制的中国方案。

As an important innovation in the modernization of China’s social governance, the “immediate response to public complaints” mechanism provides key support for the realization of a social governance pattern of joint contribution, joint governance, and shared benefits by constructing a responsive system featuring round-the-clock response and efficient handling of public appeals. Focusing on innovative practices in recent years, this paper analyzes how this mechanism, through digital and intelligent upgrading, governance process reengineering, and the construction of a multi-stakeholder collaborative platform, promotes the shift of governance model from passive response to proactive governance. The study shows that “immediate response to public complaints” is not only a channel for addressing people’s livelihood issues, but also a strategic pivot for leveraging structural changes in governance and fostering a social governance community. Its innovative practices provide a replicable Chinese solution for the modernization of governance in megacities and at the grassroots level.
