Research on the Motivation Analysis and Enhancement Strategies of University Student Volunteers' Sustainable Participation in Volunteer Service Activities

University students’ sustainable participation in volunteer service is greatly correlated with personal motivation to participate. Based on the concept of self-interested and altruistic motivation for volunteering, this paper analyzes the problems affecting university students' motivation to participate in volunteering on a sustainable basis. Accordingly, the paper proposes to establish a professional volunteer team brand, strengthen the systematic training of university student volunteers, evaluate the volunteers' participation in volunteer service, and add psychological and practical incentives for university student volunteers, to enhance the motivation of university student volunteers to participate in volunteer service sustainably and strengthen the active participation in volunteer service, thus ensuring the smooth implementation of all volunteer service.
