Abstract: Young scientific researchers are the main body of scientific research innovation activities and an important force for the output of scientific research results. To explore the influencing factors of the emotional load of young scientific researchers is helpful to provide a reference for the emotional service of scientific researchers. This article mainly obtains the original data through the scientific research social platform, and supplements the data with semi-structured interviews. We use NVivo tools to encode the original data, and then analyze the influencing factors of the emotional load of young researchers from the four dimensions of user, process, environment and service. Research shows that the emotional load of young scientific researchers is the result of the interaction between external environmental, service-level influencing factors and internal user-level influencing factors, from the perspective of the scientific research cycle. Scientific research users themselves are the most direct internal driving factors for emotional load; scientific research cycle is the intermediary factor of circular action; subject environment, working environment, family environment and information institutions are indirect external driving factors.
