The Evolution Mechanism Of Public Crisis Deduction Based On Time Window

In the modern government management, public crisis management is always a difficult point, the influence of public crisis is wide, its formation and development increasingly complicated, government prevent and control the crisis should hold the evolution mechanism of events, makes the corresponding prevention and control measures at the key time node of the event, at present the study of evolution mechanism is still in its infancy, therefore, the research of all kinds of public crisis events time window has the vital significance, based on the relevant issues of on-the-spot investigation and study, take this kind of public health events like huangpu river "floating pig" as an example, there are feasibility and practical value.The article is divided into nine parts, the first part of introduction is research background, literature review, research methods and research ideas; The second part introduces the related concepts and theories of public crisis evolution mechanism., including defining the concept of public crisis, evolution mechanism, time window, the huangpu river "floating pig"events, the main theoretical basis such as the crisis management theory, the crisis stage analysis theory, time window theory, then theoretical analysis the evolution of "floating pig" incident of huangpu river; From the third to seventh part, as huangpu river "floating pig"for example, analyzed respectively from the law of the pig death evolution of the public crisis, and the response of mass media, government, society (consumers), the producers (farmers) in the public crisis events of the huangpu river "floating pig", analysis the influence factors, and draw the curve evolution; Chapter 8 will comprehensive the third to seventh chapter, describe the degree of response curve, it is concluded that the composite curve case of the huangpu river "floating pig" public crisis evolution, the curve can describe the basic evolution and development time path of this kind of public crisis; Chapter 9 summarized the study conclusion and prospect for future research.Inference based on time window, this paper analyzes the evolution mechanism of public crisis, as the case of huangpu river "floating pig" for example, the researches on the evolution mechanism of other types public crisis can follow this research ideas concluded the time window of crisis evolution, provide certain reference significance for the government crisis management,it is also the meaning of this paper.
