The study was carried out with the goal of analyzing and studying the factors affecting the intention to donate money on social networking platforms of young people living and working in Hanoi. In the study, the authors used a combination of qualitative and quantitative research to provide a complete scale before entering into the official research. With 383 questionnaires with valid answers, all of these people have participated in online support through different social networking platforms. The results received from the survey were processed and analyzed using the supporting software SPSS 26.0 and AMOS 25. Finally, the results obtained show the importance of social networks for the effectiveness of charity fundraising in the context of the Covid-19 pandemic. In addition, the research team found that only the reputation of the organization and the knowledge, as well as subjective standards of the participants in favor, indirectly influenced their intention to donate to charity through belief and attitude.
