ABSTRACT This study examines the effect of witness-offender and witness–victim relationship on the willingness to report crime to authorities. The first objective of this study is to examine the difference between witnesses who know the offender and witnesses who do not know the offender in terms of their willingness to report crime to authorities, and to identify what factors affect such reporting behavior. The second objective is to examine whether or not there is a significant difference between witnesses who know the victim and the witnesses who do not know the victim, in terms of their willingness to report crime to authorities. This study uses a quantitative research method, and the data are analyzed using hierarchical regression. The findings of this research study are based on the analyses of the data that have been collected through a self-administered survey questionnaire distributed to 531 subjects. The results that emerged from this study show that if a witness of a crime does not know the offender or the victim, he/she is less likely to get involved in terms of reporting crimes to authorities compared to situations in which the witness knows the offender or the victim, or both.

研究证人-犯罪者和证人-受害者关系对举报行为的影响

摘要这项研究考察了证人-犯罪者和证人-受害者关系对向当局举报犯罪意愿的影响。这项研究的第一个目的是研究认识犯罪者的证人与不知道犯罪者的证人在向当局举报犯罪的意愿方面的区别，并找出影响这种举报行为的因素。第二个目标是检查认识受害者的证人和不认识受害者的证人在向当局举报犯罪的意愿方面是否有显着差异。本研究采用定量研究方法，并使用层次回归分析数据。这项研究的发现基于对通过分发给531个受试者的自我管理调查问卷收集的数据的分析。这项研究得出的结果表明，如果犯罪证人不了解犯罪者或受害者，那么与证人了解犯罪者的情况相比，他/她不太可能卷入向当局举报犯罪方面的活动。或受害者，或两者兼而有之。
