当今世界,社会实体都有宣泄社会压力的需求,这一社会现实为安全阀机制的存在提供了合理性,而少数民族地区对社会安全阀机制的需求显得更为迫切。因此,本文通过从理论根源、制度要求、现实表现三个方面,论证集合行为的预防思路应该实现由“堵”到“疏”转变的合理性。进而在“疏”即安全阀机制思想的指导下,提出非政府组织(NGO)的发展对于少数民族集合行为预防的实用性。 In today’s world, all social entities have the need to release social pressure. This social reality has provided the rationale for the existence of a safety valve mechanism, and the demand of the social safety valve system in ethnic minority areas has become even more urgent. Therefore, in this paper, from the theoretical roots, the system requirements, the actual performance of the demonstration of collective behavior of prevention ideas should be achieved by the “blocking ” to “sparse ” the rationality of change. Furthermore, under the guidance of the idea of ​​safety valve mechanism, this paper puts forward the practicality of the development of non-governmental organizations (NGOs) for the prevention of the collective behavior of ethnic minorities.
