ABSTRACT=Objective: This paper mainly studies the mediating and interactive effects of social capital on psychological capital and the feeling of happiness under the impact of COVID-19.  The COVID-19 pandemic, which began in 2020, has taken a toll on people's mental health and dented their hopes for the future.
