In the mean time, the SPSS software is used to analyses the statistical data. Finally, focused on above analysis, the relevant suggestions to prevent the social risk are proposed. Appraising conclusion shows that most sensitive people, within the scope of demolition, agree on the quasi decision-making matters on the construction project, and at least, they are not opposed to it.
