Research On The Nudge Mechanism Of The Representation Of Risk Information On The Public NIMBY Attitude

With the rapid development of economy and urbanization,the society’s demand for NIMBY facilities is also increasing.Due to the negative externality of NIMBY facilities,a series of NIMBY movements have been triggered,which makes local governments generally fall into the dilemma of NIMBY governance.The practical experience of countries with early-onset NIMBY movement in Europe and America shows that strengthening risk communication is the key to effectively resolve NIMBY conflict.In risk communication,the core element is the transmission of risk information.However,the biggest obstacle to risk communication at present is that the risk information released by the government differs from the public’s understanding,which leads to unreasonable risks perceived by the public and ultimately leads to NIMBY conflicts.Indeed,in risk communication,the public’s NIMBY decisions and behaviors largely depend on the representation of risk information released by the government.Generally speaking,any social governance measures also need to change the behavior of the target group to develop in the expected direction to achieve the relevant policy goals.This generates the nudge,which means to help individuals overcome thinking bias or use bias guide them to make expected decisions.Therefore,it is an important topic to explore how the government represents the risk information in an appropriate way to help the public understand NIMBY risk accurately and reduce the negative impact of NIMBY complex.On the basis of literature review,this study establishes a model of the impact of risk information representation on the public NIMBY attitude based on the frame effect theory.This research mainly adopts research methods of investigation and experiment to explore the boosting difference of the public NIMBY attitude,such as the literal representation of risk information and graphical representation of risk information,different representation form of graphical representation of risk information（histogram,coordinate axis chart）and color information（cold color,warm color,neutral color）.In addition,risk perception variables are introduced to explore the mechanism of risk information representation on the NIMBY attitude.The results show that the graphitization of risk information promotes the public’s stronger NIMBY attitude,and the textualization of risk information helps to reduce the NIMBY attitude;Among graphical risk information,compared to the short charts,long charts can stimulate a stronger NIMBY attitude;Different versions of the axis chart have different nudge influences.When a certain axis dimension is emphasized,the information of this dimension can promote the public NIMBY attitude better than other dimensions,and vice versa;In the color information,the warm color（red）promotes the strongest NIMBY attitude,the cool color（blue）is the most helpful to dissolve the public’s NIMBY attitude,and the neutral color（black）is between them.At the same time,the above experiments also verify the mediating role of risk perception in the representation of risk information and the NIMBY attitude.Finally,on the basis of the experimental results,some suggestions are put forward to represent the risk information reasonably and eliminate the NIMBY conflict crisis.
