当今世界复杂多变，风险挑战加剧，当前这一特别重大突发公共卫生事件——新冠肺炎疫情，极大地考验了我国当前应急管理和社会治理的能力。本文认为突发公共卫生事件的特征包括：高度不确定性、高度的危险性、高度的紧迫性、影响的广泛性等特征，要想赢得疫情防控的全面胜利，必须依靠公众力量，必须重视社会治理，特别是公众参与。因此，本文希望探索在这一特殊情境下，提高公众参与水平的可行之策。本文首先从公众参与和突发公共卫生事件两个角度梳理国内外研究现状，梳理相关理论研究脉络，在此基础上积极吸收应急管理公众参与的实证研究经验，探索从个体层面研究突发公共卫生事件应急管理公众参与研究的可行性。基于已有的研究，本文从个体主观认知的角度探索突发公共卫生事件公众参与的影响因素，关注风险感知和参与认知这两大因素对参与意愿和参与行为的影响，以及参与能力与参与意愿、参与行为的关系，从动机认知、权责认知、内容认知、条件认知、效能认知五个维度描绘参与认知变量，从熟悉性、可控性、恐惧程度三个维度描绘风险感知变量，围绕变量间相关关系提出研究假设，并建立结构方程模型，设计和发放问卷量表，以数据分析软件SPSS和Amos为研究工具，进行模型拟合进而验证假设。本文研究认为，在这一特殊情境下，公众的参与认知水平越高，公众参与行为越多；相反，公众的风险感知越敏感，公众参与行为越少，参与意愿在参与认知与参与行为间起部分中介作用，参与能力在参与意愿向参与行动转化的过程中发挥正向调节作用。基于实证研究结果，本文认为提高公众参与认知，控制公众风险感知，增强公众参与意愿是提高突发公共卫生事件应急管理中公众参与的可行方向，为相关研究提供数据支持，为更多实证研究提供经验参考。

Nowadays, in a world that is complex and constantly changing, the non-traditional security threats represented by major public health emergencies are increasingly challenging. At present, this particularly serious public health emergency----novel coronavirus epidemic has greatly tested the ability of emergency management and social governance in China. This paper holds that public health emergencies are characterized by high uncertainty, high danger, high urgency and extensive influence. To win the overall victory of epidemic prevention and control, we must rely on public power and attach importance to social governance, especially public participation. Therefore, this paper explores the feasible measures to improve the level of public participation in this special situation.In this paper, firstly, the research status in China and abroad is reviewed from the perspectives of public participation and public health emergencies, and the related theoretical research context is reviewed. On this basis, the empirical research experience of public participation in emergency management is actively absorbed, and the feasibility of public participation in emergency management of public health emergencies is explored at the individual level.Based on the existing research, this paper explores the influencing factors of public participation in public health emergencies from the perspective of individual subjective cognition, pays attention to the influence of risk perception and participation cognition on participation willingness and behavior, and the relationship between participation ability, participation willingness and behavior, and describes participation cognition variables from five dimensions: motivation cognition, responsibility cognition, content cognition, condition cognition and efficiency cognition. Risk perception variables are described from three dimensions: familiarity, controllability, and fear. Research hypotheses are put forward around the correlation between variables. Structural equation models are established, questionnaires are designed and distributed. Data analysis softwares SPSS and Amos are used to fit the models and verify the hypotheses.This paper holds that in this special situation, the higher the level of public participation cognition, the more public participation behaviors; On the contrary, the more sensitive the public's risk perception is, the less the public's participation behavior is. Participation intention plays a partial mediating role between participation cognition and participation behavior, and participation ability plays a positive regulating role in the process of transformation from participation intention to participation action. Based on the empirical research results, this paper argues that improving public participation awareness, controlling public risk perception, and enhancing public participation willingness are feasible directions to improve public participation in emergency management of public health emergencies, providing data support for related research and empirical reference for future research.
