公益研究

自从进入21世纪以来，大学生公益实践逐渐成为我国高校思政体系的重要构成和实践育人的关键载体。运用CiteSpace进行文献计量分析，结合基于机器学习的BERTopic主题模型的语义主题挖掘，对我国大学生公益研究的热点议题与演化趋势进行分析，发现大学生公益研究涵盖志愿服务管理、育人价值实现、参与动因、模式创新发展、国家战略对接及理论体系建构等六大主题，呈现出“理论—本质—实践”三维的知识特征。研究演进具有明显的阶段性特征，从早期的概念初步认知与实践探索，逐步深化至价值重构与模式创新，最终形成服务于国家战略需求的学术探讨。未来，学界应从研究内容、研究对象、研究学科和研究方法等方面持续深化大学生公益研究。

Since the advent of the 21st century, university students' public welfare practice has gradually become an integral part of the ideological and political education system and a key carrier for practical education in Chinese universities. Utilizing CiteSpace for bibliometric analysis, combined with semantic topic mining based on the machine learning BERTopic model, the study analyzes the hot topics and evolutionary trends of the research on university students' public welfare in China. It is found that the research encompasses six major themes, namely volunteer service management,realization of educational value, participation motivations, innovation and development of models,alignment with national strategies, and construction of theoretical systems, presenting a threedimensional knowledge characteristic of “theory-essence-practice”. The evolution of the research exhibits distinct phased features, evolving from the initial conceptual understanding and practical exploration in the early stages, to the gradual deepening of value reconstruction and model innovation, and ultimately forming academic discussions that serve national strategic needs. In the future, academia should continue to deepen the research on univerisity students' public welfare from aspects such as research content, research subjects, research disciplines, and research methods.
