Abstract: The global public security system is generally faced with the common challenges of frequent emergency in dangerous state, the outofjurisdiction in normal state and recurring insecurity in future state. Under the systematic, stable and forwardlooking problem analysis perspective, the six elements of mission, tool, structure, function, attribute and path are extracted.Aiming at the triple goalsof dangerous state security, normal state security and future state security, static system construction must be carried out closely with these six elements: The first is the “foundation framework”, which compacts the “foundation” through missions and tools; the second is the “supporting framework”, which establishes the “pillar” through the structures and functions; the third is “extended architecture”, which “extends” the system through attributes and paths. On this basis, contingency orientation should be adopted and sustainable dynamic sound ways of implementing the public security system should be selected flexibly by stages, levels and focuses so as to accelerate the realization of these three goals.Firstly, to improve dangerous state security in “reinforcing plate” way, it's needed to integrate the highrisk response mechanism,to combine the prevention and control mechanism and to joint the risk correction mechanism. Secondly, to improve normal state security in “optimizing system” way, it's needed to establish the preventive and warning mechanism, to build the responsibility implementation mechanism and to innovate the intelligent riskcontrol mechanism. Finally, to improve future state security “developmental” way, it's needed to strengthen the emergency learning mechanism, to optimize the performanceoriented mechanism, and to incubate the social consciousness mechanism.

摘要： 全球的公共安全体系普遍面临着危态频突发、常态易脱管、未态屡无感的共性挑战，问题导向的系统性、稳健性、前瞻性剖析，可提炼出使命、工具、结构、功能、属性、路径六项要素。为实现危态安全、常态安全、未态安全的三重目标，必须紧扣六要素开展静态的系统建构：一是“基础型构架”，通过使命和工具夯实“地基”；二是“支撑型构架”，通过结构和功能搭建“支柱”；三是“拓展型构架”，通过属性和路径辅助“延展”。在此基础上还应遵循权变导向，分阶段、分层次、有侧重地实施动态健全：一是危态安全的“补短板式”健全，融合高危应对机制、结合联防联控机制、联合风险整改机制；二是常态安全的“优系统式”健全，创立预防预警机制、创建主体尽责机制、创新智慧风控机制；三是未态安全的“重发展式”健全，强化应急学习机制、优化绩效导向机制、孵化社会自觉机制。
