【摘要】 预审是法律规定我国公安机关行使的基本职权之一。在诉讼制度改革深入推进和犯罪形势变化的背景下，如何把握我国公安预审的职能范围以及预审职能通过何种方式实现成为公安机关相关部门亟须解决的现实问题。公安预审职能实现方式经历“侦审分设”、“侦审合一”、“大法制、两统一”三个阶段，其发展演变存在制度、法律、环境、效益、思维五个方面复杂的影响因素。我国公安预审应在确定其承担证据审核、引导侦查、监督制约职能的基础上，选择由公安法制部门承担预审职能的“法制预审”模式。更多还原

【Abstract】 Pretrial is one of the fundamental statutory powers exercised by China’s public security organs. Under the dual pressures of deepening judicial system reform and evolving crime patterns, defining the functional scope and identifying optimal implementation approaches for pretrial procedures have emerged as pressing operational challenges for public security agencies. The evolution of China’s pretrial system has progressed through three distinct phases: the “investigation-examination separation” phase, the “investigation-examination integration” phase, and the current “comprehensive legal system with dual unification” phase. This developmental trajectory has been shaped by five interrelated factors: institutional frameworks, legal provisions, operational environments, organizational efficiency and professional paradigms. China’s pretrial system should adopt the “legal department-led pretrial” model, wherein the legal affairs department assumes responsibility for three core functions of evidence verification, investigative guidance, and procedural oversight This model demonstrates strong operational feasibility and presents a viable framework for optimizing China’s pretrial procedures.更多还原
