Routine Activity Theory (RAT) and the general theory of crime have been widely employed to understand cybercrime victimization. However, there is a need to integrate these theoretical frameworks to better understand victimization from a cross-national perspective. A web-based survey was conducted among participants aged 15 to 25 years from the U.S., Finland, Spain, and South Korea. Factors related to RAT were associated with increased victimization in all four countries although results varied between the countries. Low self-control was associated with victimization in the U.S., Finland, and Spain but not in South Korea. Using decomposition analysis, we discovered that the association between low self-control and victimization occurred both directly and indirectly through measures of RAT. Our study demonstrates the need to integrate theories to better understand the dynamics of victimization. Despite the usefulness of RAT, other theories should be taken into consideration when investigating cybercrime victimization.

例行活动理论（RAT）和一般犯罪理论已被广泛用于理解网络犯罪的受害者。但是，有必要整合这些理论框架，以便从跨国角度更好地了解受害现象。对来自美国，芬兰，西班牙和韩国的15至25岁的参与者进行了基于网络的调查。尽管四个国家之间的结果各不相同，但与RAT相关的因素与受害的增加在所有四个国家中有关。在美国，芬兰和西班牙，自我控制能力低下与受害有关，而在韩国却没有。通过分解分析，我们发现低自我控制和受害之间的关联是通过RAT的措施直接或间接发生的。我们的研究表明需要整合理论以更好地了解受害动态。尽管RAT很有用，但在调查网络犯罪受害时也应考虑其他理论。
